Hey I will try to keep this short and to the point. For some time, I have been considering whether or not to sell my 2007 Silverado. It is coming up on needing a lot of work and I figure if I can scrape up the cash to make the payment on a newer Silverado/Sierra it might be worth it. Before I forgot it is 4x4 and has about 95,000 miles on it. It is a long bed and has the 4.8 V8 engine. 

 

Anyway, the truck has been suffering from what I would call 'considerable' rust underneath to the frame and now it has began to get around the bottom of my paint job and chip it off. I was thinking about sanding it down (or having someone do it for me) and painting the lower six inches or so black. I have seen it done on a lot of trucks. It is also coming up on new brake pads, possibly calibers and rotors as well. Also it has never had the transmission oil changed so I am planning on changing the filter in the pan and doing that as well. So basically I am sort of beginning to wonder if I should consider selling it and purchasing a newer one. However, the truck has never left me on the side of the road and runs great.

Also the repairs you mention are one and done for a while.  With new vehicle prices the way they are you may be a much happier man fixing up your ride and living payment free.

Thanks for the reply Buckshot I appreciate it. I just published another post about changing the transmission fluid. Hopefully I will get some good feedback from this cool community. Anyway the rust on the underneath it is pretty bad I would say. However, it has just gotten to the very bottom part of the actual body so it really is not even visible yet. 

 

I am not sure if I mentioned this before but I sort of got tricked into putting truck tires on my Silverado. I got "talked up to it" if you prefer. The truck definitely has more traction but the Cadillac ride is lone gone now. I really miss how smooth my truck used to ride, it is the main reason I bought a Silverado. I am thinking about selling the light truck tires and buying passenger tires again. My buddy told me he wished he would have talked to me first as he could have told me the ride was going to get rougher. He said that they are better on the bigger trucks (2500-3500) as they weigh them down better.

If you tow a trailer the LT tires are fine.  But if you don’t, get the passenger tires when they wear out.

 

take some pictures of the rust and post them.  The repairs you mentioned are no big deal at all honestly.  I was on the fence with mine and assumed rust was real bad, but after looking at darn near everything I realized it wasn’t that bad.

 

There will always be something to fix but it’s usually cheaper then a $500/month truck payment every month.

Yeah I am leaning towards keeping the truck. It (like everywhere) has been raining every single day. I am going to change the transmission fluid as soon as possible and will try to snap some pictures then. There is just a lot of expenses coming up with the truck and thought maybe it would just be better to take that money and put it towards a new one. Plus changing the transmission fluid is always an uncertain thing but I think it will be okay.

Sorry it took so long guys. I am focusing on getting my transmission oil changed out right now. Which can only be described as a pain in the @$$. I have a detailed thread of how that project is going on here as well. Anyway these are the only pictures I have taken thus far as the body goes. That entire area that I marked with a red box is now completely hollow. I just applied a little pressure to it and it easily collapsed. I will take another photo showing what I am dealing with now. 

 

I realize I will now be fighting an uphill battle as it rusts from the inside out. However, I might try to purchase some of that mesh netting from Bondo and fill it in with the other filler material they sell, paint it Victory Red, and hope it holds up for awhile. What do you guys think?

That’s not bad.   I knocked out rust, power washed the inside and sanded or cut away most the rust i could.  I then unloaded rust inhibitor inside the rocker when it all dried.  The power washing sort of cleaned out the weep holes in the rocker and it was amazing how much flakey rust blocked those up.

 

I now just deal with it and ignore it.  Everything else on the truck is decent  

 

You put bondo and mesh on that without addressing some of the rust, it will just spread and bubble next to your bondo job and it will be a waste of time and money.  Worst scenario, the rust festers while sealed from the outside and rots your inner rocker panel.

Hey greatmizzou and Buckshot556,

 

Thanks for your responses guys. I just took a picture of what it looks like now that I cleaned some of the rust out of that location. It was literally just flaking off, I am surprised that it did not give way while driving it. It does not look good, but not particularly bad either. Anyway it will give a better idea. I just took this other picture of my truck too. You probably cannot believe that it is the same truck.

 

Also I just began another thread regarding my tires and ride I mentioned earlier. It is located at the following link.

Not a body man, but here's what I'd do if you have access to a small MIG welder. Cut back the rusty parts to good metal. That's going to open up some body cavities. Use a good rust converter (as opposed to a rust inhibitor) on everything you can reach inside. CRC makes a good one. Then use the rust inhibitor on top of that. Weld in new metal, using the converter/inhibitor on the inside before welding. Sand the welds down, do the converter/inhibitor outside, then paint. It isn't a guarantee of stopping the rusties, but it's about as good as you're going to get.

Yeah I understand, I think I feel more like greatmizzou in that I do my best to ignore it. However, I would like to get some of the structure back and possibly paint it. Then be happy with that for several years before looking at a new truck. I have not welded since High School either, but guess it is never too late to learn again. 

 

My father said to put a piece of sheet metal there and rivet that in, and fill it in with some bondo. I would be happy with that even if the rivets were sticking out and it was a little uneven. That side of the truck you see in the picture is where the hole is. So you cannot see it without looking under the truck right now. So restoring some of the structure and holding off on any extra damage for as long as I can is really my only goal.

      2020 Silverado 3.0 LM2 Engine/Trans Failure
      By Jake_Melvin1
      I have a 2020 RST with the 3.0 LM2 Duramax with 79k miles… the flywheel failed when I was driving down the highway and left me dead in the water.. I had it towed to the dealership 4 weeks ago and they called today and said the transmission and the engine needs to be replaced. Has anyone experienced this with their trucks? I never towed anything heavy and was religious with service.. luckily all covered under the 100k powertrain warranty…

      Transmission or tranfer case? Electrical or mechanical?
      By AaronandAlicia Dailey
      OK everyone I want to give thanks ahead for any advice and help.
       
      Truck in question= 2003 Chevy Suburban Z71, 5.3 L         Transmission= 4L60-E
       
      So the story started when I was going down the road at about 50mph in cruise control, when suddenly I heard the engine begin to rev up. I hit the brake to take it out of cruise control and the engine stopped revving up. Apparently I lost transmission of power from the engine to the wheels because no matter what gear I put it into now, I get no movement from the vehicle. No reverse and no D1, 2 or 3. When I put the vehicle in park and attempt to push the vehicle it will not roll. When placed in any other gear I can then roll the vehicle freely.
       
      Before this happened: Since owning the vehicle 4x4 has always been shifty.....hehehe...sorry couldnt help it. I have the model where there are 4 buttons with lights the buttons are located left hand of dash near the turn signal. When I first got the truck sometimes it seemed like it didnt want to switch between gears. for example I would have to hit the button multiple times before it would switch and even then it seemed like it hadnt really switched but the lights would indicate it had. Most of the time the light for the button I selected would flash multiple times and then return to previous selection. Often times after turning the vehicle off and then returning to vehicle to go somewhere I would find that the light has switched back to a gear that it wasnt in when i left the vehicle. It seems to favor 4x4hi. As of lately I havent been able to get the lights to switch at all. It seems to be stuck in 4hi permanently.  
       
      I have tested the 4wd switch and its fine. 
      I tried unhooking battery for half hour with lights on to reset PC. I then reconnected battery cable and turned vehicle on but not start it. Then I pulled a bunch of fuses and plugged them back in. ( seen it in a video and the guy said it was supposed to wake up the TCCM) Well that did nothing. 
      I have the truck off of all wheels right now and was trying to figure out if the transfer case is stuck in neutral. With the truck in drive as I turn the rear draft the front moves also. I am assuming that means it is in 4wd. But should I have someone hold the front drive shaft while i turn the rear drive shaft to confirm its not just from friction or something.
       
      I actually have the front drive shaft partly out right now in an attempt to get at and remove the shift motor and manually put the transfer case into 2hi.
       
      I am also considering changing out solenoids. I have gathered it is unlikely the shift solenoids. Is it possible it could be one of these:
      1 * EPC (Pressure Control) Solenoid
      1 * PWM Solenoid
      1 * Manifold Pressure Switch
      1 * TCC Solenoid w/Harness
       
      Another thing I suspect which would be an easy fix is the transfer case fluid level. I removed the fill plug and nothing came out. I can tell it has been leaking. I would have already topped it off but I have been stuck at home (no running vehicle lol). Could low fluid cause this issue? I hope that's all it is lol. Anyways I got a ride to the store tomorrow and to look at a back-up vehicle. Anything you guys recommend to grab from the parts store while I'm in town tomorrow?
       
      What would be your guys recommendation on how to solve this problem and fix it?
       
      All help is appreciated.
      thanks in advance,
      Aaron

      RIGHT TO REPAIR
      By customboss
      "Opinion ‘Car Talk’ host:
      Independent auto shops deserve the right to repair your car
      September 28, 2022 at 7:00 a.m. EDT
      (Washington Post staff illustration; images by iStock) Ray Magliozzi is one half of NPR’s show “Car Talk,” a longtime independent repair-shop owner, a Dear Car Talk columnist and a car reviewer on CarTalk.com.
      When your car breaks, what do you do? Okay, after you utter a certain word? You have to decide where to take the car to get it fixed, right?
      You really have two choices. You can go to the dealership or an independent repair shop. However, some car manufacturers don’t want to share key information for diagnosing and fixing cars with independent shops — and that’s something that’s not only bad for repair shops but also bad for you.
      As a radio host who has advised thousands on their car problems and as an independent shop owner myself, I know all too well that car owners benefit when they have more choices. Congress is considering a national “right-to-repair” law, and lawmakers need to pass it to protect your rights as a consumer.
      Story continues below advertisement
       
      Back in the old days, when people were still switching over from traveling by mastodon, you repaired cars with your eyes, ears, nose and hands — and, if you were desperate, a Chilton repair manual. Now, you often repair a car by first plugging a computer into the on-board-diagnostics port and seeing what the computer tells you is broken.
      So, what’s the problem? Carmakers and their dealerships want to maintain control of modern diagnostic tools, which forces customers to come to them for repairs. Even though independents are willing to pay to license these tools, dealers see an advantage in exclusivity.
      Dealerships have always had certain advantages. They have better coffee in their waiting rooms. Heck, they have waiting rooms. They have clean restrooms that don’t double as auxiliary air-filter storage. They also work on your particular make of car all day, every day. So they might be familiar with an oddball problem because they’ve worked on 4,000 Camrys.
      Story continues below advertisement
       
      Independent shops are small businesses, run by individuals — some of whom are terrific people and mechanics and some of whom will blame your car troubles on demonic possession and give you essential oils to fix it.
      But independent shops have their own advantage: price. Their labor and parts costs are usually much lower — hey, who do you think is ultimately paying for the dealerships’ coffee and fancy couches? Some research has found that dealers, on average, charged as much as 20 percent more than independent shops for the same repairs.
      This article was featured in the Opinions A.M. newsletter. Sign up here for a digest of opinions in your inbox six days a week.
      There’s also the matter of distance. Not every town in the United States has a stop light, let alone a dealership for every car brand. There are 16,752 franchised car dealers in the United States, according to the National Automobile Dealers Association, but there are nearly 240,000 repair shops — meaning that for a lot of people, an independent shop is the only nearby option.
      Story continues below advertisement
       
      At Car Talk, there are times we’ll strongly recommend an independent shop for standard work like brakes, shocks, the engine and regular service. And there are times we’ll recommend going to the dealership, like when you have a particularly rare problem that might be unique to your make and model. But at the end of the day, you should take your car to the dealer to be fixed because you want to not because dealers have hoarded all the key information.
      Beyond the information needed to diagnose and fix your car, dealerships also want to maintain control of your car’s telematics. What are telematics? Well, now that everything is connected to the internet, your car can notify your dealer when your car needs an oil change or has a blown sensor. Using the software they’re denying to independent shops, the dealer can then diagnose the trouble code, call you and schedule a repair. Most modern cars already have this ability.
      Car manufacturers point to the importance of keeping your car’s data safe — including your location, say — as a reason to deny independent shops access to these tools and codes. They are right about the need for data security, but part of privacy is that you should be the one to decide who has access to your data.
      Story continues below advertisement
       
      At least 17 states have laws on the books stating that your vehicle’s data belongs to you. Many independent repair shops will need to invest in tools to keep customer data secure, but just because they’ll need to invest doesn’t mean they can’t compete with dealers. Lack of choice — and competition — is never good for the consumer.
      So consumer groups and independent shops are promoting what they call right-to-repair legislation, guaranteeing consumers more choice by requiring automakers to license their data with independent repair shops. The voters in my fair state of Massachusetts approved just such a law in 2020. In 2021, 27 states introduced or passed similar legislation. Beyond those state laws, there’s a national push to protect consumers and independent shops. H.R. 6570, a national right-to-repair bill, has been sitting with the House Energy and Commerce Committee for months.
      My Car Talk colleagues and I know not everyone will support right-to-repair laws. Dealerships won’t like the level playing field. Mechanics might not like how much work they’ll actually have to do. Still, this is an issue everyone else can get behind. If you own something, you should be able to choose where to repair it. "
