Bad lean

mrskiff · August 21, 2018

I have a 2018 Silverado double cab. It has a 2.25 inch level but not sure that matters. I have a bad lean in the rear. My passenger side sits 1 inch higher then the driver side. The front is even. Anyone else have the issue and if so how do i fix it. New leaf pack? Its very noticeable

My 02 Duramax had the same problem. A local alignment shop adjusted the front end to even up the left rear so it was level with the right rear.

Thanks for the info. What in the front end was out of spec to affect the rear?

They make adjustments in the front that just affect the rear. Take it to an alignment shop or a good dealer

'02 was torsion bar, new ones aren't.

2018 rcsb z71 also has bad lean . Passenger side rear way high and also very noticeable. Anyone had rear leafs changed out under warranty’ to FIX this?

Ill prob take mine to dealer. I notice it only does it sometimes though. After driving a while it levels out. I just scratch my head. Leafs and everything look good. I notice a big difference in the gap between the bump stop and the axle..

This is known as a chevy lean.

I have read about it somewhere on here.

Thank you. Read through the link. A lot of the replies talked about fixing truck yourself with homemade spacers to mask what is really causing the truck to lean. My truck is outside the GM specs and just trying to find someone with the same problem and what was the cause and how did GM fix the leaning problem. Possible leaf springs out of spec, possible body mount? Very curious to find answers before taking truck back to dealer as this problem was not listed in current service or technical bulletins.

From what im gathering its fairly normal. I will most likely be lifting my truck so im hoping having new blocks and/or rear leafs fixes it

Mine had a 1" lean.

Found it to be bad factory Rancho shocks.

They were shot and driver rear was binding and sagging.

Was the binding and sagging the leafs and shackle and could they be loosened,then bounce or cycle the suspension and then tighten back up with the weight back on the springs to get truck leveled(or close) ? Or did the sagging require new leafs?
