My 1969 Camaro's left rear spring is sagging. Springs are multi-leaf(5) springs. Wheel wells measure 27 inches off the ground, except the left rear, which is 26 1/2 inches. Wheels are 15 X 8 rally's all around and 235/60's up front and 275/60's on the rear. Rear tire(s) scuff the wheel well when I hit a bump. Can I just install a 1/2 inch block between the spring and shock anchor plate to raise the car? Would that give me the proper geometry. Thank you.

no.it would actually lower car more, need to re arc spring or put airshocks on car

Bill,

Friend installed air shocks and said ride was rough, so I think re-arching springs is the way to go. Thanks for your input...

Odd that it's just left rear. I've seen cars with very obese drivers that weakened both left springs. I'd pull the rear end loose on that side and check for broken leaf. if not replace rearch both rear springs.

Check the air in the tires, 1/2" could just be the difference in inflation between 2 tires. A better measurment is from the center of the wheel (or axle flange/hub) to the fender lip as it eliminates the tire from the equation. Make sure the cars is on level ground too, it makes a big difference!

I would un-bolt the shocks and lower the car onto the suspension, bounce it a few times then measure again. This will tell you if you have simple shock problem or if you need to dig further. Also make sure you don't have any extra weight sitting on one side or the other that could mess with your measurments.

If it's not a shock then you have to start looking into several things. You could have a bad bushing (spring eyes, upper shackle bushing or body bushings) all can effect how the car sits. It could be the spring itself as well...

As a temp fix you could use a block as you asked about but on the opposite side to lower it to match but don't plan on this as a fix for the problem because what ever is causing this in the 1st place will likely keep going over time.

1/2" isn't very much and depending on overall condition of the car may just be normal wear. Without knowing the cars history over the past 40years don't be surprised if the answer remains elusive until you do a frame off restoration or have changed out a lot of parts and one day it magically sites level. Start with the shocks and other simple stuff I've suggested, you might get lucky...

Why is it always the left side that seems to sag? Could the driver's weight cause this? Seems unlikely.

For most of I think not, but for the very obese yes it does take it toll n the springs. I used to do wheel alignment for a Firestone store 8-10 a day. I had one car I had to have the service manger hang on the open drivers door while I set the caster and camber to keep it form pulling, the weight of the driver made it change enough that it would not track straight with him in it.

As suggested, a 1/2 inch is pretty good tolerance.

A better measurment is from the center of the wheel (or axle flange/hub) to the fender lip as it eliminates the tire from the equation.

If the tire were low, wouldn't it lower the center of the wheel (or hub)?

Yes it would lower it but the distance from the center of the wheel up to the fender lip won't change...

Ahh,..
