Hello,
Thanks for letting me join. I have a 53 Bel Air that the pass side wheel leans to far inward. I can move the front control arm eccentric bolt but it doesn't move the wheel far enough to straighten it out. I don't see any other adjustments or places for shims. Help!

I’m not familiar with the setup on these cars. But what you are describing is a camber problem, not caster. Caster is the angle of the steering knuckle front to back. I know ‘55-‘57 Chevys sometimes suffer from crossmember sag. That is when the crossmember between the front suspension bends down in the middle and let’s the frame rails get closer to one another, which pulls the upper control arm mounts inward and tips the tires in at the top.

Here is the link to the shop manual that describes the front suspension and how to align it.

I had a shim under the lower control arm, when i dis-assembled mine. I probably need to put it back in...

Thanx, got my words wrong. I'm new to this site so I'm still trying to send a pic for reference. Anyhow, I don't think this beefy axle/cross member is gonna sag!

Thanx, I tried moving the pivot pin but it doesn't move far enough to fix my problem. Soooo...a shim(s) installed under the bottom of the control arm will bring the top of the tire out? Makes sense.

The shim under the lower control arm is for caster adjustment.When there isn't enough adjustment in the upper shaft.Wont move the top of your wheel out as that is a camber adjustment. You must have worn out upper bushings or a damaged upper control arm, It could also be that the crossmember has been bent.

I'll have to check again. All bushings are new and I checked the control arm and cross member.

I have consisted slitting my front arms and moving the ends of them forward 3/32 or so. That would add caster. Likely after adding power steering

You can add castor by shimming the lower control arm.

I am installing a Calivier rack this winter. I have all the brackets made just waiting for some other parts. I am also installing left side Corvette adjustable tie rod sleeve. Hopefully this will tighten up the steering as a 1954 steering box helped but it still has some play it the steering.

Isn’t that kind of “the wrong direction“ like an up and down instead of for and aft? Must take a lot of shims?

Caster is adjusting the tilt front and back from vertical. If more caster is required that the adjustment will allow, one side of the lower control arm can be shimmed.

Yes, but I am just wondering how that all plays out. Sliding the control arm mounting points forward with dramatically increase adjustability with only a small amount of sliding. Shimming would require quite a bit to amount To the same degree of adjustability, right?

What are you using to check camber. What does the other side read?


Car sits level left to right? Not too low in the front?

Shepherd,

I'm just using a bubble level for now. I have the fenders and hood off and pretty sure the alignment will change after the weight of the parts are back on. The driver side is straight up and down. The pass side leans in at the top. The camber adjusting bolt won't move the top of the wheel out far enough. The ride height isn't too low and she sits pretty level (barely off a little)

Ok, look for looseness in the kingpins, wheelbearings, any thing worn in the control arm bushings.

Make sure king pins are tight.....check
Make sure new bearings are tight...check
Make sure new control arm bushings are tight...check
Look for bent or damaged parts....check
Make sure spring is in the right position...check
Make sure new shock is installed correctly...check
Make sure new sway arm bushings are tight...check

What did I miss?? haha

My '54 has about 1/4" of shims on the passenger side lower control arm, and it just barely has enough range to meet specs. I did't add these; possible may be part of the original assembly process.

I can assume you are referring to shimming the control arm shaft?
