Having trouble w/ pinion yoke splines

sarge · 04-22-2010, 12:44 PM

So I got a few minutes to go out and work on the the 60's yesterday. I pulled the shafts out of the rear and then pulled the diff. and pinion out .... no problem . I start to reassemble with the 4.10 pinion and I can't get the yoke to slip down far enough to get the pinion nut to bite :confused: even stipped out one pinion nut ...... what am I doing wrong ...... I currently have th pinion in the deep freezer and plan on heating the yoke to see if it will help . Spline count is the same so no it's not the wrong yoke or pinion . Last night before grabbing some zzzzz's I pulled the pinion out of the freezer and checked the yoke slippage and it seemed to go on much further . Are the tolerances really that close ???? or am I f'n up something.

I always had to put a spreader and a block of wood in there to hold the pinion to deadblow the bearing on there... even before the yoke...

I don't think you're doing any cursing that I didn't do.

your right Brad , I stepped away and took a breath and everything came together, got the gears swapped in both axles ..... now it's time to bite the bullet and pull the Jimmy in the garage and start unbolting and cutting :)

Good deal! I was scratching my head on what it could have been other than maybe too small of a hammer.
