If one side is really half a degree more than the other (don't know how this could happen unless the inner knuckles were removed and turned) even if you shim the axle to have say 5 degrees on one side and 5.5 degrees on the other, the steering will pull to the side with the most positive caster on a flat road. Half a degree difference is enough to make the steering pull to one side. You can add half a degree of caster to one side with an offset ball joint from moog. I had to do this on an XJ once.

But, I still find it hard to believe that your caster is that far off from one side to the other. You can not correct the difference with shims. When you rotate your axle with shims both knuckles will be turned by the same amount.

Centering Pin

I'm fixin' to do the same job. If I buy new centering pins, do I need to get longer ones?

Yes, if you install shims, your old centering pins will need to be replaced. Usually when you buy them, they are oversized and need to cut off the excess length once they have been tightened down. As stated earlier, it's advisable to get steel shims that are designed to be bolted to the spring pack (they last longer and are more secure).

If you take your spring pack apart its a good idea to remove the rust between the leaves and apply a coat of never seize in between the springs. You will be amazed at how it softens the ride.
