Hey guys

 

I've checked through the search engine but haven't been able to find anything.  It seems to me that the Left rear corner of the truck is sagging or squatting down more than the rest of the truck.

 

Anybody else have this expereince?  What'd you do to fix it?

 

Thanks

Sean

Well, I can tell you that if it's the left rear the cause of the sag is the hundreds of pounds of gas in that side.  The only fix for that is to never fill your tank more than 1/4 full.  Sorry, but there's nothing you can for that one.

Well, I'd almost buy that train of thought except it is a shortbox with only 26 gallons of gas and it does it even when empty.

 

But maybe that's just the way it is...

 

Any other thoughts/ideas/suggestions????

Sorry, I don't have an answer for you, but I can tell you my '91 2WD reg. cab short bed did the same with either a full or empty tank.  :D   It wasn't real noticable, but it did it.

Do a search on something like this.  I seem to remember another user having this sort of problem and how it was fixed.  I think it may have involved a slight torsion bar tweaking or maybe even shims under the body mounts.  Going from memory this is something that the dealer should help you correct.

 

Good luck.

There was a guy here a long time ago with this problem.  He had to have the rear springs replaced on one side.  The dealer claimed he had been overloaded but did the warranty work anyhow (if I remember right?!?!)

 

Appearantly one of the rear springs had lost some of it's arch...

I'd start from the ground up;

 

1) Check tire pressure

2) Check all suspension componentry

3) Check torsion bars.

4) Check frame

5) Check bed mounts

Saw one on the lot like that recently.  When I looked closer, the airbag had colapsed on that side.  Don't know how you fix one of those -  ???

We had the same problem with out 2500HD work truck, called the dealer, he was aware of the problem. He said they usually take the trucks to a spring shop and have the springs re-arched. He ended up not re-arching our springs though, the work order said they adjusted the ride height. I assume they adjusted the torsion bars. I just bought a 2002 2500HD myself and it appears to squat a little

I've mentioned this before and I'll say my two cents again.  I noticed after I fully cycled the suspension a few times.  I mean like over 3,000lbs of payload.  This corrected the sag and the back of the truck sits very level now.  Try it and see. :D

      The Peckish Synapse

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      By Brendan C · Posted

      New to diesel trucks. I happened to find my oil cooler leaking oil externally with only 4,000 miles on the truck. I didn’t realize this was an issue until I started researching it. Dealer is going to replace it under warranty but I’m wondering if there’s anything GM is working on to fix this issue. I’ve heard the oil filter used is the same as they use on their V6 motors and that’s what is causing the problems. Should I switch to a bigger filter or keep using the OEM recommended?
