Default Vette has a rear tilt

Greetings

My car is tilted to the left as seen from the rear. Front is OK. Is this adjustable by shimming the rear leaf spring?

It can...but if it was level and now not...then something has happened......collapsed spring, missing rubber bushings, etc.......need to get it in the air, pull the spare tire carrier and inspect.....post some good clear photos here of the whole rear suspension.

Good Advice....and take pics/inspect the FRONT suspension TOO. Something could be wrong that is causing the rear suspension to lean.

POST PICS OF ALL COIL SPRINGS AND LEAF SPRINGS BEFORE THE CAR IS LIFTED OFF THE GROUND/you will have to lay down beside each wheel to get good pics using a flash camera.

Good advice by all. I would add to check the pressure in all 4 tires. Check and record the dimension from the floor to the top of the arch opening at all 4 wheels too.

It is either sagging suspension or crushed body mount.
The frame to ground spec should point to which.

And check your rear spring bolts to make sure they are the same length and tightened the same. As your tighten the nut on the bolt that side rises. But just raising it could be a band aid like the others have stated

Good advice, like the old Chilton's sequential logical troubleshooting, Ha!. Ditto here. After rebuilding the rear end on my 68, the RH rear quarter was sitting about 2" higher than the LH. So, I checked all, checked prior photos, trying to figure out what went wrong with the rear rebuild. Getting ready to remove rear spring, check TA's again, remove body? and then I noticed the LH front tire was low, Oh well, this was an easy fix LOL's!

Looking at your photo and the exhaust, I would agree the body mount may be the problem.

When mine sagged on the driver side it was the original steel leaf spring getting uneven over the years. The driver side has all the passenger weight on it almost all the time. You can adjust at the bolts, loosen the spring and tap it sideways, or re-curve the spring. Might need new bolts to adjust enough. Move the spring too far and you have to grind the end off to not hit the tire. I had the old steel spring re-curved to original specs, but then it sat too high and I needed to get lowering bolts to get a proper ride height.

If you have access to a four post lift, that would be perfect for diagnosing your problem. Drive it on and not disturb suspension levels. Chip.

OK, you have to promise not to laugh at my suggestion, but it's for real. On our '68, I noticed a pretty big drop to the left rear after a 50 mile drive soon after we got it about 3 years ago. Didn't see it at first because I just put it back on the stacker when I got back and lifted it up so I could park one of the dailies under it.

When I dropped down for the next ride, I noticed the left rear looked about 2-3 inches lower than the right. Kept looking and saw that the left rear tire camber looked out of whack. Put it back up in the air, and found the left rear camber adjusting bolt had loosened (whoever did the last alignment must not have torqued it enough). I adjusted the camber the best I could without an alignment rack, torqued the nut/bolt, but it back down and it was perfect ride height. Figured I'd take it to my alignment guy and get it done.

Took it for a short ride, got back, and it was lowered on the left rear again - and I could tell from the rear tire that the camber was out again. Put it up on the lift and found that the camber adjusting bolt 'keeper' (you'll know what I mean if you've ever looked at one) was stripped due to the bolt being loose. Located some NOS camber adjusting bolts, replaced it, got it aligned, and no problem.

So, in addition to the good advice you've received in the thread so far, you might take a look for this issue. Please let us know what you find. Best, Paul
