My cutlass has a driver side lean in the rear any input on what maybe causing this? Have relplace the rear shocks and springs. Did not fix the problem. Starting to look at the front end for faults should I do this or is it in the rear??? Crazyboutolds has given some input but still looking for more.

 

No Accident, No rust, No bent trailing arms... Crazyboutolds recommended looking at bushings. Which sounds good.

 

You know, I have heard of this problem. I think it is common on Cutlasses. I have heard some people just install air shocks and put more air on one side. I think it might have something to do with the perch points for the rear trailing arms. I am not sure. Do a search here or at realoldspower and you might find something.

 

Could you measure the frame at particular points and compare left to right? Maybe you could identify or eliminate something that way. Sort of what Jesse was getting at about the perch mounts. You could determine if it was the frame or the body that is lopsided then.

 

I have the same problem too, even after replacing all springs and shocks front and rear. Am about ready to go to airshocks in the rear, as Olds64 mentions above. If anyone here has a definitive solution, I'd love to hear it.

 

We need a good frame and body person on this site.......

 

If it's the G-body in the picture that you're talking about, have you inspected the frame for rust? These cars are notorious for rust in the rear frame rails. Second, inspect for cracks in the spring pockets in the frame that could be allowing one side to sag. I had this happen on a 70 Supreme. Third, inspect the rubber body mounts as well as the tabs for them on the frame. Again, deteriorated rubber or rusted mounts can cause a sag. Finally, have you verified the problem is with the frame, or the body? With the tires properly inflated, park on a flat, level surface. Carefully measure from the ground to the underside of the frame rails at a number of reference points. Compare the two sides. If the frame is parallel to the ground, the problem is the body.

Oh, and you DID remove the 455 block from the trunk, didn't you...

 

Definently check all your body mounts, and your shims for your axle. Its hard to tell from here what your problem is, lol reminds me of jeeps, they all lean to the left, no matter what you do, LOL

 

I couldn't agree more.

FWIW, I actually took my car to a body shop that has a frame machine, and had them check the frame. All was fine there, and L/R measurements were the same.

 

Some great advice Joe... definitely things I'll be looking at. Thanks!

And oddly enough, while not a 455 block in the trunk, that was where I had my tools. I removed them and it did seem to help a bit. Next experiment will be to see if it levels it if I put them on the right rear.

 

I have the same problem...but I'm thinking its my "Big Ol' Behind" that is causing the issue.....
