the front pinion angle is pretty bad off on my samurai since i finsihed putting on yjs and a SR....just wondering if there is anyway to measure how many degrees the pinion angle is off, and how do just running axle shims do other than moving the spring pads?, Thanks for any help

Angle finder is a cheap tool at home depot. The problem is you can't rotate the pinion without effecting steering.

Agreed, if it is driven on the street, Caster is 10X more important than the pinion angle, otherwise you will have death wobble and wheel centering issues. Find out what your factory specs are for the caster and try to get it close to that, then worry about pinion angle.
 
well it dont see the road but for mabey a mile or two every several months so that no big deal....the prolem is that the angle is so steep that the yokes at the transfer case are hitting once my front end barely lifts from the ride hight at all
 
hmm, never heard of that (im still new to the building part of things)....what would that do?, just sorta lenthen it a bit?
 
It would give you more clearance at the yoke allowing for more angle at the yokes before binding by offsetting the bearing caps rather than having them directly inline with each other. Tom Woods sells them I know, but I do not know who makes them. Maybe some of the driveline vendors here could help?
 
TC drop

I can't remember if the Samurai case is divorced or not, if not, that would make his angles worse in the front, if it is divorced it would help some, although I'm not sure how much it can drop with that short shaft.
 
Yep, your right. I was thinking the rear.
 
well i figured out today that my pinion angle is off a few degrees, so im gonna try to get some shims and try that first....if not, then i guess ill just try and figure it all out as i go

-but yeah it is divorced, and havent thought about doing that....probly what i might try if it still binds when i get the pinion angle back to where it should be
 
Changing the pinion angle isn't really going to help anything on the transfer case side....You may need to look into a CV joint at the transfer case side of the shaft. If you shim the front axle to where it has the right pinion angle (same angle as the t-case) you will have just as sharp of an angle at the pinion as the t-case.
 
the trasfer case, measuring off the flange is at 87 degrees, leaning backwards....the front diff, again measured on the flange is at 85 degrees opposite from the TC....the rear diff is at 75 degrees....the front driveshaft is at 20 degrees, the rear is not in it right now so cant measure it.......if anything is wrong about the way i measured all this let me know, like i said before im new to the building part of things. Any help to get all this figured out would be great, thanks again
 
push the knuckles off and rotate them. did it on my 60 with minimal effort and no cost. stuck that pinion sky high. offroad you get plenty of oiling with the hills and such.
