I am chasing a vibration in my 360, have replaced everything, and when pulling the balancer they noticed it had about 3/16s of end play, a little too much... I haven't pulled the thrust bearing, which is the next step, but I am wondering..

I changed rears with a a splicer U-joint on my original 8 1/4 driveshaft... the rear is raised Day 2 style... Now I am wondering if the driveshaft was a little too long and the front yoke has pushed things forward and wiped out my thrust?

I seem to remember a difference, but don't remember if it was too much or too little..

Also, can I change a thrust bearing without yanking the engine if I have access to a lift?
