The Leaning tower of first gens

Hi everyone. I have been looking through old posts and found some small morsels of help. Which I have tried but still no luck.

My 68 vert is leaning down on the drivers side. It is about 1 1/2" lower than the right. I thought I might have had a saggy Mono leaf so I swapped them over for some 1.5" drop multi leafs from hotchkis ( also changed the front springs). I was confident this would solve it but after finishing and driving around it still is exactly the same. So I had read people had put lowering blocks on the high side. So I have installed a 1" block on the passenger side between the leaf and axle and I still have 1" difference. So the block has helped but something is still trying to lean it over. I measured the front and I have about 7/16" difference floor to arch. Has anyone had this problem? Could it be the front subframe mounts maybe?
Thanks for any help in advance.
Ben

Check your subframe bushings. How are the door gaps to the rocker and quarter?

Re: The Leaning tower of first gens

It's your front springs If the sag is on the right rear, it is your left front spring pushing up more than the right. Common issue is the pigtails of the spring are not in the pockets.

But check that everything is straight, subframe bushings, bent subframe, sagging front springs, etc can all be the issue.

Re: The Leaning tower of first gens

can you use a aluminum Leaf Spring Lowering Block on the opposite leaf spring to try and level the car if everything else is new ? The block would raise not lower the car

Re: The Leaning tower of first gens

Unsymmetrical use of blocks etc to level a car this far off is poor practice imho. Identify the root cause and address it properly....

How will the leaf block raise the car ?

If its under the axle it will drop.

Re: The Leaning tower of first gens

Make sure you tighten the rear leaf-spring shackle bolts with the full weight of the car on the suspension.

Re: The Leaning tower of first gens

If one of the front coils was not indexed and set in the cup properly than the opposite of the car will be low. Confirm your front springs are in right

with that said 1 1/2" is a big difference so IDK if a mis aligned spring can throw it off that much

Do you know if the unibody is twisted?

Just like 1st gen mustangs the Camaro unibody was prone to twisting when guys started making HP and clutch dumps & 1/4 mi launches without sub frame connectors

If you have replaced springs F&R and other suspension parts....they all should have been tightened with the suspension fully loaded. If done while suspension was hanging...one side will certainly be off.

Re: The Leaning tower of first gens

A-arm bushings, shocks, leaf spring bushings among other things could contribute to the issue.

Thanks for all your answers. I have already put an aluminium block in the high side drop down. Made a difference but not fixed it. I was careful to index the springs in the pockets but maybe I should double check. I indexed in the top pockets, that's correct isn't it? I will check the sub frame bushings next. I have no idea if the body is twisted. Most lines are ok on the car. Not perfect. Drivers door isn't inline properly but the hinge has worn and I have new pins and bushings for that issue. I will re check the front end first then check all the body bushings. 👍

Re: The Leaning tower of first gens

The other way to check, is to get some angle iron and put it pointy side up on a floor jack (with a rubber cushion) in the center of the subframe crossmember. jack it up so front wheels are off the ground (or remove wheels before hand). If the rear evens out, the issue is in the front, if rear still leans (bounce it), then issue is in the rear.

Re: The Leaning tower of first gens

Are the front sway bar "end links" the exact same length? Also check for worn end link bushings.

Re: The Leaning tower of first gens

Step one is to disconnect the front and rear sway bars unbolting one end link per bar is enough. Jack up the rear on the exact center of the rear axle and check the front for level. Then jack up the front on exact center and measure the rear for level. This will tell you which end is the problem.

I will try the angle iron trick and see if that shows up any problems. The sway bar is brand new, new bushings and end links too.
