ANOTHER 8.8 pinion angle question...

[35Remmy]

Just for clarification, the spring pads will be welded on at a NEGATIVE 6 degrees...pointed DOWN...so when they are level, the pinion is pointed UP at 6 degrees....right??!!!

I keep seeing 6 degrees...but if u welded these pads on at a positive 6 degrees the pinion would end up pointed down!!

Am I crazy???

Well, I'm not sure about your number (not saying you are right or wrong, saying I don't know) but you are correct about the direction. Pinion angle is the angle of the pinion above a level plane, so you need to weld the pads so the pinion points up at the desired angle.

Yes, pinion should be 4-6 degrees up.

ive been going crazy over this myself. since im swapping one in my truck with roughly 4" lift and 2pc drive shaft. every diagram i see either talks about a one piece shaft or double cardan but cant seem to find anything on a two piece. i had lift blocks that were tapered but then took those out and replaced with exploder springs and extended shackles on my old 7.5. but then i blew out the rear shortly after(im guessing due to not shimming the axle and throwing off the angle) so im not sure if i should weld the perches at the factory 6* and use the tapered lift blocks instead of the stock block with the bump stop. or remeasure my angles and adjust and weld at a totaly different angle(other than 6*)

I have installed quite a few rear axles in my rig over the years. For a 2 joint shaft, I have found the easiest way is to put the axle under the rig and with the rig back on the ground, use an angle finder on the t-case flange and then rotate the differential flange until it is the same angle minus 1 degree down. This will compensate for pinion rise. Then weld the perches and be done with it. A double cardan or 3 joint shaft is quite a bit different, but it sounds like you have a 2 joint model. Hope this helps some.
