Lean to the left

[Georgew48]

Before committing to the hard stuff try this, crawl under the rear end. Loosen the left side spring u-bolt clamp. Tighten the right side then the left side and check the frame to floor measurements. This worked for me.

Do I need to install the spring spreader before I try your method of loosening ther left side u-bolt clamp or is it safe to loosen them a little bit and tighten the right side then the left?

You don't need to install the spreader to do this.

Milton has it right. It worked for me when mine was leaning a touch to the drivers side.

Had the same problem on my coupe. Turned out number three spring was broken. I highly recommend you use Slip Plate as a coating on the springs versus some type of grease. You can purchase it from Napa and use a 2 or 3 inch roller to paint it on. You should have 3 coats top and bottom on all leafs. You can see a few pictures of how we replaced mine here.

I also had a lean to left. The rear spring center bolt was broken causing the leafs to shift. Replaced the bolt and no more lean.

Thanks, I haven't had time to really take a close look at the center bolts.
