-4 deSrees is seriously off!
Wedges are the Devil's Spawn! The can corrode, break and generally do a [email protected]
job. Your best bet (I assume that you have a SPOA lift) is to cut and reweld the perches.
Hey Ack....thanks for the encouragement and info.
Yes....my new aquisition does have a SPOA lift, 84 Toyota axles and 33'' super sw. tsl's.
I dropped the front axle and found 5 deg. wedges on the perches.......BACKWARDS !! I removed them and got a almost neutral caster. I have a fastrax cast/camb guage that works pretty good. I don't work as good as the guage though as I missed my mark of rewelded perches at +4.5. They turned out equal at slightly over +3 deg. (no wedges)
Driveshaft didn't suffer any at the slightly steeper angle.
My wife followed me in the minivan and flashed the lights when I hit 60 on the blacktop ( I was reading 67). Steers great, centers after a curve when you let the wheel slide through your hands. I'm thinking it's good enough and may get a little better with less agressive tires. It sounded like a "air- raid siren" !!!
Thank again Ack. I really appreciate your FAQ's site. Helped me a bunch!
