Default Aligning the camber??

After I installed a new mono leaf spring I now have negitive camber and with the rear wheels not touching the ground they are perfectly straight. So I was thinking that I could adjust the strut rod to give me positive camber (not too much) while not touching the ground then should settle into a nice straight up and down stance when back on the ground. So do all you do is break loose the pivot bolt then rotate it to where you want it? I would like to try this myself. I have no shops where I live that I trust.

Yes, the wheels are not set to 0 Camber. I don't know off hand what degree they are at but it's not 0..

3/4 Positive would be perface setting. Range is from 0 to 1/1/2 positive for 71 to 73 only. All other ranges start Positive.

Positive camber sounds pretty bad... these things tuck under a LOT. I can't believe that there's a book out there that recommends it.

The MVMA spec for 78 says start at -0.875deg +/-1/4.

The reason why I'm doing this is the rear tires tilt inward now with the new spring. My car is a 82 if that makes a difference??

NO!!!



1/4 degree negative camber is a good setting for handling/tire wear.


To the OP, the reason your camber changed is because the car is now sitting at a slightly different ride height. Before setting the camber, let the car settle a little, by putting some mileage on it, and then make any necessary adjustments to the ride height, then set the camber....

Free advice: find one. You cannot accurately set camber with the tires off the ground. You can get close enough to drive safely to the alignment shop.

The only way a spring change can affect camber is if the ride height has substantially changed. If this has not changed, the camber problem was already there.

as Mike said, check the ride height first before messing with the camber. The half shafts should be close to parallel with the ground. You may need longer spring bolts. Look at the rear suspension section page 6-6 and 6-7 of this publication to find out how to set the rear height.

hello, don't mean to hijack your thread, but I just finished doing this to my 82 and thought you may find it helpful, the aligment specs are also listed for the rear wheel camber, if I can help you out in anyway, will do my best..not saying what I did was the correct way for the alignment, but it worked for me, hope you get yours sorted out.....Tom

Yes I decided against doing this myself and yes again the height did change. My car used to sit as if it had air shocks on it. Spring was cracked. Now it sits pretty close to level and that's why the camber changed so much. From the manual it stated that the bottom of the front rocker moulding to the ground should be 7" and the rear end of the rocker moulding should be 7.2" Mine was 6.75 front and 9.25 in the rear before the spring swap.

I purchased a cheap set of wheel dollies from Harbor Frieght several years ago just for this purpose. You drop the car down on the dollies, bounce it once or twice, then set your alignment to the required specs - with a carpenter's lever modified to fit the rim of the tire. This method will suffice till you can get the car to an alignment shop.

You're learning. I agree: have the car aligned.
