Caster question

[hollowbase]

I just finished installing the Skyjacker 2 1/2 inch lift. From reading and researching I came to the conclusion I would need 4° caster shims. I installed them and went to the alignment shop and ended up with left @ -3.0 and right @ -3.7. It seems to drive just fine once the toe was corrected. Are these acceptable numbers? This is with stock manual steering.

No, the #'s are bad. Did you install the shims with the fat end towards the front? Negative caster would offer white knuckle driving.

pictures of how the shims are in place would help

 

[hollowbase]

Fat end is to the rear.

Is that backwards?

Believe it should be to the front. I have the same skyjacker 2.5 with 4* shims (stock length shackles) and if I remember correctly my castor angle is 2ish*

Is that backwards?

Yes

Okay, thanks for the quick respo

 

[hollowbase]

Meant to say, thanks for the quick responses.

One more question. I turned the shims around and since I was -3.0 will that now turn it into a +1.0 and will this change my toe in?

not going to change toe in
I can't believe the aligninment place didn't say something about the negative castor.

+1 or a little more is good; toe will remain the same.

I'm actually dissapointed in how they presented me with the information. I should have been better informed before going there in regards to what it should be.
