I thought Iíd share to help some people out with lining up their axle. I saw a few people having trouble here and there.
This isnít about dialing in caster/pinion, thatís another thread. Anyways...
I may have subconsciously stolen this idea.
I needed to roll my axle to fit my lower arm. Once I pulled the second one off, passenger side, the axle rolled out. I needed to roll my lower mount up to align the holes. This makes sense given the track bar location. My dumbass left everything connected. In order to roll it back, I hooked a ratchet to the lower C and the crossmember and ratcheted until I was aligned. Easy as can be. Iíll probably do the same for uppers.
It made it pretty easy to check angles without a lot of extra work too.
fwiw, many of us will use our floor jack prior to disconnecting any arms or linkages , placing it right on the tail of the differential where the pinion gear tail is ; that way it is a simple matter of slight lifts/lowering that will yield rotational movement of the housing. I sometimes use the shock mount , as well.
Unless you have to remove all CAs , and due to the movement you experienced, working a single controlarm at a time is much less work, tho not always possible.
I did run one at a time. I thought I was going to be clever with wheel stops and prevent axle rotation, my arms werenít changing length (werenít supposed to be). Oh well. I never tried the pre tension on the pinion, Iíll have to keep it in mind next time.
