My '99 Trans Am's entire rear axle isn't painted, coated, waxed, or otherwise protected at all.

 

Just sayin'

Not sure what your sayin' or how exactly it pertains to the thread? Is it rusting? if so, is it due to no protection? If not, our trucks are and that is our point.

Ok, I am new to this site but as a GM tech who has been pushed too far, its time the truth came out! I know for a fact in the northeast, there is a service bulletin #PI056E: and its titled wax coating

That's not acceptable! Looks like it was done by a blind man. I'd be back there demanding to know why they had the truck for 3 days and that's all they accomplished. I sincerely doubt it's GM's fault,

Well, now you see the GM manufacturing trend for these trucks. The idea is to produce a comfortable vehicle with a car like ride, silent interior, and loaded with gadgets. This is bound to impress t

Heck ya it's rusty. It was covered from hub to hub while sitting on the lot. My point is, GM didn't even care to attempt any corrosion protection on that vehicle. Our trucks are pretty much entirely covered in something. Good or bad. Granted, the TA didn't cost $50k. My axle still works.

My frame was in the same boat. Its currently receiving the TSB fix for the rusty frame problem. My 2004 silverado that I sold before buying the 2014 didn't look like this until 3-4 years.

They are going to be "fixing" applying the TSB resolution steps to it shortly.

I know this is like the 4th thread I've responded to on this issue but it irks me so much I can't let it go. I'm in the same boat as you guys. I'm getting the TSB repair done next week but I don't have faith it will work. Something happened with the frame prepping process before these things were dipped which is why the garbage wax coating is peeling so easily. I've only had my 2014 truck for 2 months and it looks worse than my 2007 silverado did after 7 years. Bottom line is a frame shouldn't be rusting this early. Ford doesn't. Toyota doesn't. Nissan doesn't. And Dodge doesn't. So I dont like being told this is normal and acceptable for a Chevy. It's un acceptable and Chevy needs to improve their design. They tout this as being the most corrosive resistant silverado ever which is true for the body, but they did nothing to improve the frame. Anyway I'll keep everyone posted on how my repair goes as well.

What was your build date, where was your truck built.

Mine was built September 2013 in Mexico.

I was at the dealer yesterday and I looked at 2 new trucks that just came in and now they have a clear like glaze sprayed on the frame and rear axle. Maybe they're addressing it at the factory now?

Wow, that is the worst rust on a 2014 I have seen to date. Unfortunately, all they will do is spray on 3m rubberized undercoating which will last a few months. This is what we did when I worked at a dealership back in the day.

I have to get some pics up..they just fixed the bad areas..they did follow the tsb to a tee for those areas.They didnt use a spray, they used a brush. They used the products listed in the TSB. Took them 72 hours as they had to account for dry time in between coats.

I don't think I got the TSB fix on mine. Apparently my VIN number wasn't one of the ones in the recall. They cleaned the rust and sprayed the spots with a black coating I think by 3M but it was an overnight fix. Not the 72 hour job you guys are describing or the thick painted on product. Anyway they missed some of the rust spots so we agreed they would fix it all when I bring it in for my next oil change to cut down on the number of trips to the dealer. I'll see how the current repairs hold up in the mean time.

 

I personally don't care much about the look of the rust, it's a structural issue for me. I just want to know the frame will last 10 years and not break in half.

The proper stuff to use when touching up the frames on these trucks is in an aerosol can bearing GM part number 12346501. It is a match to the color, texture and overall appearance of the factory applied coating. I touched up a couple of small spots on my 2013 frame and it looks spot on.

Heres the page I posted the TSB on with all the info> http://www.gm-trucks.com/forums/topic/158444-factory-undercoating-is-peeling-off/page-2

 

But in short they are "recommended" to use the following products:

  • Using Lloyd’s Pure Prep™ Metal Surface Preparation P/N 25418 (10 fluid ounce bottle), or equivalent, saturate a towel or Scotch-Brite™ (3M) pad with the pre-diluted solution and scrub the area well, rendering a foaming of the Pure Prep.™
  • Apply a light flash-coat of Lloyds Kryptonite Metal Treatment P/N 36502 Life Long Rust Protection (14 ounce aerosol), or equivalent, to all rusted and bare areas of the frame where the wax coating was removed. This first coat should flash in approximately 3-5 minutes.
  • We suggest top coating the Lloyds Kryptonite with Daubert Nox-Rust® P/N X-121B “One Coat Rust Preventative Coating” (aerosol), or equivalent.

    Note: As shown in the graphic below, besides adding a corrosion resistant layer, it dries to firm, wax-like film which will more closely resemble the appearance of the unrepaired areas of the frame.

With that said, they can use aerosol or equivalent, which they can use a brush type system to prevent it going everywhere and looking on mine, you can see brush strokes, not spray (they may have used spray up until the final thick heavy coat).

At least GM is using a quality product, I'm looking forward to you posting some actual pics of the job these guys did.

      GM discontinuing interior parts on a 5YO vehicle??

      By Atlas · Posted

      If one can't be found, a good automotive upholstery shop should be able to replace/sew in a new panel where the damage is on the old cover. It might not be the cheapest option..

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      Does your dealer charge you for the tire rotation on top of the oil change price ?. I haven't had any service work done at my dealer yet other than when I brought it back soon after owning it to have the front end aligned to correct the steering wheel being off center a bit. Oh they called me at least twice hounding me to bring it in for an oil change and pushing a 300.00 package of oil change and tire rotation and whatever other quick simplistic checks they would do. Only going off of what a friend gets charged for his half ton for the basic oil change and its the same amount of oil as the L8T holds, it was about 150.00. Once one buys a set of tires from most shops these days or so I believe, they will do free tire rotations and some do free tire balancing as well as free tire repairs.    Certainly doing a tire rotation is no five minute job, and definitely not at home but because I run a set of winter tires on their own wheels, I swap them at home and its a one tire at a time deal because of the tire season swap although I jack up the rear and do it and drop it back down and then raise the front and do them and coordinate the tire rotation into that process for both sets of tires. I am using a floor jack though and if I need to raise both ends at once I use a couple sets of jack stands to have all four tires off the ground. I use either an air impact or battery impact and have electric impact as well so no shortage there of easy methods to spin the lug nuts, and then retorquing the lug nuts. None of it goes quick though but my wages are cheap though ... zero. I live an hour out of town, its easier just to do things like that myself than waste a bunch of time in town and having to make an appointment and probably a special trip and sit there at the tire shop waiting for them to get my vehicle in and get it done and not screw something up in the process.

      Clunk when coming to a stop... driveshaft/slip yoke? Mechanic couldn't recreate it

      By mrbflat · Posted

      I do have the 8 speed.  Interestingly enough, after driving my truck for the past 2 days now, I have not had the clunking issue at all!  I am beginning to think it may have been suspension/leaf spring related, and somehow when the shop put my truck on the lift to do their initial inspection, it relieved some built up tension/pressure that was causing my problem.  I swear it felt I was a bull rider on a bucking bull the way the truck would almost rock back and forth slightly before the big thud/clunk when coming to a stop.  I am hoping I got lucky here and it's gone for good.

      Bring it to discount tire. They do free rotations even if you didn’t buy your tires there. I didn’t believe it until I tried and they did. You can tip the employee if you would like

      Best part of this video is how it resets expectations. Wonderfully done piece. It also made clear a few points I've made from day one. Detergent oils DO NOT KEEP A MOTOR CLEAN at the recommended or longer change intervals. They just get dirty slower than a non-detergent oil and there isn't spits difference between them on this point if they carry the DEXOS license. Great thing about the license that gets missed is it assures CONFORMITY even it that means a low bar.    One thing he did not talk about that I paused on an magnified was the condition of the oil ring separator. Besides a stuck ring a plugged separator and land drain back is huge when it comes control. We see in short order improvement in control IF that is the problem.    Another item I took exception to and he did not make plain was the condition of the timing chest and under valve cover having something to do with indicating piston cleanliness. Schaeffer's Oil makes that same omission in their million mile Ford video. I'm guessing he has never torn down a Red Line HP, AMSOIL SS motor that has been on that diet from the get. What he showed in the video was a good deal of varnish. Something totally absent in Peppers 165K cover off look. I smiled because he did his at the same milage.    He also makes the mistake of assuming oil temperatures in the pan are the temperature all over the motor even though he makes note of the piston being the hottest part of the engine. that baffled me a bit.    I can tell you from personal experience and witnessing teardowns of family motors that even oils of the 1960's would keep them squeaky clean when OCI's were 1500 to 2000 miles without exception. At 3K and above you get what he experienced and the longer you leave it the quicker to gets to the junkyard.    I think his is missing a opportunity not tearing it down again when he's done killing it. Time would be his only cost.
