My left hangs lower than my right as well....always has since I started paying attention to it more in high school. :rollin:

 

 

I'm impressed with your dedication to towing your trailer correctly. "Most" people just hook up and go, and we usually find them in the ditch or with blown out tires. I'll make sure to give you a thumbs up if I see you trucking down the road!

Thanks. Im quite amazed at how many people don't care about these things.

 

I want to make sure things are done right. No way Im putting my family in danger over something I can fix or change.

right, but would it put weight back onto the front wheels is the question?

 

Correct, airbags don't move weight around. What they do is make your suspension much, much better under load. A WD hitch can only do so much--you'll still have around 100% of your tongue weight on your rear axle. Making your suspension better will be beneficial even with a WDH. Your measurements show you're restoring about 100% to the front, you really don't want to exceed that.

I ordered a set of Sumosprings. I looked at Timbrens but decided Sumosprings would be a better option to just firm things up when hitched up.

I don't even add air to my bags when towing. The bags really shine when I need to haul a 2,400 lb. pallet of coal in the back - will make the truck sit dead level ... unlike this truck here:

Obviously he needs a front hitch a cargo carrier. Equalize some of that weight.

I think you've got it about perfect... Just practice safe towing driving techniques and you'll be fine

That was the only time that truck ever had a nice ride quality ... :lol:

 

Actually in that pic, there's about 3k in the back. :uhoh:

Hit the scales. Much better this time around. Although i was only able to do what i did last time, as there were people there using it, so was limited at the time i had.

 

So I added to the front, took some off the rear. reduced overall weight. I had no water, no mother in law, but went from an empty tank of fuel to a 3/4 full tank. I've got about 50lbs in my E-rated tires. May go up to 60 or so. See if that firms things up more or not.

Well, I kinda made a boo boo. Changed two things, and towing is horrible. Its so squirmy, is the best way I can describe it. You'll be going along, then the rear feels loose to the right, you correct and it quickly comes back, so you correct back again. It just seems like its a constant battle squirming around.

 

SO first added the sumo springs in the rear to replace the factory bump stop. You can see in the pic here they are just touching when everything is hitched up. I also switched tires. Went with Cooper discoverer atw LT tires. I had them at 55psi. On the way home i bumped the from to 65 and the rear to 70 to see if it would get rid of the squirm. I guess the easiest thing to try and remove the SumoSprings and see if it gets better. I cant really swap tires again.

 

I hate trying to throw money at this. You think it be worth replacing the shocks and struts? They're probably the original ones. 135km on the truck. Besides that, Im not sure where to go next. Larger front/rear sway bar??

Usually you will get a squirm like that if the trailer is loaded too tail-heavy. Thing will want to constantly whip above a certain speed. If you can move more of the cargo forward of the trailers leading axle, it may help some, rather than having to spend money on parts.

hmm, that makes sense then. So with the sumosprings, its not allowed the rear to come down as much, and with the hitch adjustment I did before, its putting to much on the front of the truck/rear of the trailer. So I guess the simplest solution would be to adjust the hitch back to the previous spot if Im keeping the sumo springs on.

Anything added to the suspension of the truck shouldn't make a big difference in handling - the most noticeable factor in handling is weight distribution. If you don't have a minimum of 10% of the trailer's weight as tongue weight, things will get hairy. 15% is better. If you don't know how much weight is where, when in doubt, move the cargo towards the hitch.

 

With my flatbed, whenever it gets squirrelly like that, I'll unstrap the car and pull it forward 6" - makes all the difference in the world. Will transform the behavior from a whipping, swerving death trap over 50 mph, to smooth as glass up to 75. Over time I've learned the best place for the front wheels to be on many different vehicles so that doesn't happen. The weight distribution setup I got also made an enormous difference in how it all handles too. I haven't had a white-knuckled ride in a long time. :lol:

well, it seemed much worse this past time and I know we packed no more, maybe less then usual for this trip. The only difference was the tires and the sumosprings. I'll adjust the WD hitch back to the previous spot and see if it makes a difference. Go figure this was the one time I didnt take it over the scales. doh

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      2020 Trailboss 6.2 replacement

      By 2017Z · Posted

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
