Well I searched the relevant boards & came up with nothing....
I just installed SLR UCA's (sans diff drop for now) and went for wheel alignment.
Camber was brought into spec (thank goodness) but caster couldn't be improved beyond -1.7 driver & -1.4 passenger (spec is 1.7 - 2.7 degrees).
I've never heard of this problem before with any of the UCA's out there.
Problems associated with negative caster are livable (no abnormal tire wear but sensistive steering at high speeds, which I have noticed slightly but then again this could be primarily due to the lift itself).
Still, I'd like to try to correct this.
Any ideas out there?
BTW I also installed the Fabtech AAL and the SLR 1" rear shackle IN ADDITION to the Rancho AAL I already had in place. The rake isn't too bad (about the same as the Rancho AAL alone with a 1" T-bar lift).
The ride is good -- the back end with the Rancho RS9000's set to '2' rides only a tad softer than it did set to '3' before the added lift. Also the 9116 in the back limits droop but I think the 9112 will fix this (9112 is 1.15" longer compressed & 2.25" longer extended -- I don't know if longer compressed length will prevent full tuck -- something to look into).
One more item:
Is there anybody out there who has actually removed the stock diff-mount bushings without the use of a press? Right now I'm thinking of attempting a combined drill/roto-zip/torch approach but I'm wondering if this would lead to merely a 1/2 day job or more like a full weekend of blood/sweat/tears/regret....
Any feedback is mightily appreciated; also I'll do some measurements if anyone's specifically interested...
