I cut and turned my axle on my 60 last weekend. I used the stock perches as a reference, and prior to turning i had 1.5* difference in the reading from the perch to the degree finder sitting on the opeing for the trunion bearing. After cutting the knuckles I turned them to where the reading was 7.5* difference from the perch to the reading on the opening. My question is was that enough rotation or should I have gone further. Trying to take a short cut i had decided to use the top perches with the ubolts saddles as my new spring perches. I welded a 1/4" plate on to and drilled for a the centering pin. I filled the "saddles" with grade 8 bolts and welded them in. Is my pinion angle going to kill me or can it be adjusted with shims, which would effectively reduce my caster reading??? Right???? Will a CV be able to handle this pinion angle with out major problems??

Come on... Some body should have some kind of feeling about this. If I did things wrong, please tell me. I still have not put everthing together, so i can fix things if i have too. Please...sob..sob..sob

Thanks for any info...:smokin:

I can't speak with authority on the FJ60, but in a SO FJ40 the pinion is typically rotated upward in the range of 12-15*. In order to increase the caster angle above the +1* stock setting, it is then necessary to rotate the knuckles back more than the pinion was rotated up -- something like 15-18*. It doesn't sound to me like you rotated enough.

If you rotated your pinion somewhere between the original angle and an angle where it points directly at the transfer case output, neither a CV joint nor a standard u-joint arrangement will work without vibration.
