My 1970 Deville is showing signs of wearing the inside side of the tire on the passenger side of the car only. Which I understand is negative camber.
Which way do I need to turn the camber eccentric to give it more positive camber.....counterclockwise or clockwise? and how much of a turn should it be.....1/8 of turn, 1/4 turn or some other measurement?
FSM says + 3/8 degree to - 3/8 degrees adjustment max either way....what does that compute to in terms of turning the eccentric ???
The FSM says the "final position of the joint stud should be in the rear portion of the camber eccentric in order to keep steering arm angle correct" Does that mean that the side of the eccentric in which the stud hole is closest to the edge should be towards the rear of the car?
Just remember, making any adjustment to that eccentric also changes the caster. Best to find an alignment shop in the area that has knowledge of these cars.
Look at your upper control arm bushings too. Mine were badly worn and trashed my tires in a very short time.
With the wealth of Cadillac enthusiasts knowledge on here, and no answer about the questions I posed. I'm saddened
btw, the upper control arm bushings and ball joint are brand new.
I'm sorry I didn't monitor the forum yesterday afternoon.
Clockwise out, Counter in. Is it possible the eccentric got moved without indexing it when the bushings were replaced?
I have independant shop and dealership experience aligning front ends. Years ago I crewed on a thunder roadster racing team. Front end adjustments were a way of life at the track. We used portable turntables and bubble indicators to adjust the front ends during practice, a few times after straightening things that got bent after hitting a wall in practice. Same for the guys running Super Stocks, Late Models, Modifieds and Sprint cars..
Using your eyecrometer to adjust camber isn't going to work well. From a zero position to get 3/4 of a degree which is 45 minutes of angle you will need to move the eccentric approximately .070". No way I do that without using a bubble indicator. And yes, I know that the actual number is affected by the radius of the eccentric. I only mentioned it to indicate that a little movement makes a big difference.
Amazon has bubble indicators. Google Toolwiz Camber adjusting tool. $12. It'll get you close. There is also one on eBay for about thirty bucks that appears to be good quality. If I didn't have a Snap on WA40, it would be my choice.
Be sure to check the toe in after you finish with the camber. You may want to check the other side if you get the tool.
Good news is if you really mess up the adjustments, nothing will fall off assuming you tightened everything you loosened so you won't kill yourself driving to an alignment shop.
