They are already installed so I guess I didn't take a really close look at it. You are probably right. The jeep is only going to be driven ocasionally on sunny days, so I am not too concerned about durability of the shims. I have not installed degree shims before and would appreciate any direction? Do I purchase longer bolts and bolt the shim to the leaf springs? Would welding the shims to the perches be stronger and more secure?

That would lead to my next question, please forgive if it seems a bit ignorant. Instead of turning the knuckle, would it not be easier to reset the spring perch back the required 4-5*?

With a great Jeep comes an empty wallet.

I believe you meant rotate the perch forward on the tube, but the question was understood.

While easier than rotating the knuckle yoke, that will also rotate your pinion down by the same amount.

This is how NAXJA Midwest Chapter elected officials like to treat their resident users and former multi-year supporters.

If the caster is moved negatively (axle rolled forward) due to a lift, isn't it conceivable that the pinion angle will be moved from its original position? And, the proper way to fix this is to modify the spring perchs of rotating the “Cs”?

Yes, but that's not a do-it-yourself job that many folks can do. That requires the correct tools and skills and most likely a jig for accurate placement of the angles involved.

I took my cj7 in for an alignment thinking the toe may have been off, came back with the following:

Left Front: Right Front:
camber: -.04 -.04
caster: 4.3 3.9
toe: .05 .04


so my question is this, the caster is about 2* off, but i've had it up to 80mph on the interstate and it tracks straight and effortless ... as such, I'm tempted to leave well enough alone being only 2* off and not having problems (?) any opinions?

Do you have lift shackles? The stock ones are 3" bolt to bolt

i''ll measure them, the PO put the 2.5" skyjacker lift on (sorry thought I had that in my sig.)

as CSP posted I'll probably leave it alone ... as much as I prefer to have things correct, since it isn't giving me problems and won't ruin my tires no reason to change it up right now

Castor is not an exact number it must be. It should fall within a range.The fsm for later Jeeps put's the castor at 5-7 deg. pos. That doesn't mean that 4.75 deg. is going to give you poor steering, only that it's heading that way. So if it works where it's at... leave it. As CSP said, "if it ain't broke.....

thanks for the confirmation, I was more worried toe was off and would rip up the tires since I had just gotten the jeep and noticed some weird lug wear on the fronts ... wasn't sure when I got the results back if I should address the caster or not so I'm just going to leave it alone until a problem develops
