The Chevelle “Lean”

I’ve read a lot of posts about how Chevelles lean to one side. It seemed to me that most of those posts referenced sitting low on the drivers side.
So I went and looked at my 66 and it looked like it was WAY low on the passenger side. Probably because the suspensiongets a little twisted when I pull into my driveway at home.
So I drove it back to my shop today which is real level and measured it. I measured from the ground to the wheel opening at the centerline of each wheel and got:
Right front - 23”
Left front - 23.375”
Right rear - 23.75”
Left rear - 23.75”
So I’m off by just 3/8” in the front with the drivers side high. Probably not bad given the tolerances used when these cars were built, 53 years of driving around and a frame off restoration.
What do you guys think?

Re: The Chevelle “Lean”

Needs springs...and perhaps some suspension bushings..

Re: The Chevelle “Lean”

I'd be happy with 3/8ths of an inch.

Re: The Chevelle “Lean”

Add your weight to the drivers seat and watch that variance disappear. Now, if your passengers weighs more than you, it's a moot point.

Re: The Chevelle “Lean”

My right rear is lowest, never measured, but from the back it is obvious. So I figure once my fatass gets in, all good.

Yeah, I’m happy. I think I’m probably better than most at this point

Yeah, it’s low. Dropped spindles and short springs.

Re: The Chevelle “Lean”

Dennis, did you check for equal tire pressure on the fronts? 3/8" isn't much.

Yes, tire pressures are equal.

I’m not going to mess with it. It’s almost perfect to me.
I only brought this up because I’d seen in older posts that a LOT of people had issues with lean AND the fact that they all seemed to be complaining about being low on the left side.

Re: The Chevelle “Lean”

Had same issue on my 66. At one point someone placed a spacer on one rear spring and clamps on the other rear spring to level the car.
When I ordered new 1-1/2" drop springs, the lean was very obvious!
I ended up returning the new springs and went with QA1 adjustable coil overs instead. Now the car sits nice and level plus I can adjust height if I wish.

Yeah, 3/4” is a lot. Was it a 3/4” spacer and do rear spacers go on the top or bottom of the spring?

Re: The Chevelle “Lean”

From my experience, start with the springs, make sure static height and wire thickness is the same, but even with that out of the way, there can be a variance. Check the body bushings and frame (at least eyeball the frame). 3/8" is one things, 3/4" is quite another. Personally, if you're going to deal with one corner sitting lower, it would be the passenger rear, which will put the driver side front higher. Air bags with individual lines are a coil spring suspension's best friend, simple to install and do a great job flattening out the suspension. Often only takes a few pounds difference to level out a suspension.

This is correct, if you want to test this theory do the following:

Get a friend or someone else to help you. Example: So, If your low on the driver's side front, stand in front of the car with your friend at the passenger side rear bumper. Have him/her push down slightly on the passenger side corner of the bumper. Note, it does not take much as GRN69CHV states. You will see just how little it takes as your friend can probably produce the level you want with two fingers pushing down.

Re: The Chevelle “Lean”

Even though I hate to mess with it being so close, I could take the battery, which is tiny but in its stock location and remove it. If that gets rid of the 3/8 difference in the front I could relocate it to the trunk, probably in the middle so as not to affect the rear.p

Anything you do to one end will effect the other.
