energy suspension polyurethane body bushings question

That's what I was worried about when I replace mine.

So - charlie, I should measure the exposed threads before removing the pinion nut? Or measure the exposed part of the pinion before removing?

[Charlief1]

Take a punch and dimple the end at a specific location, then make another on the nut that lines up with the first. Count the threads so when you start going back together with it the "dots" line up and you have the same amount of threads exposed. Did that make sense Mark?

[SuperSix]

Yes sir - makes perfect sense. Kind of like replacing a tie rod end.. Count the turns, etc.

[Charlief1]

LOL I always measure the tie rods from outside to outside and use that. It keeps it a little closer that way.

just checked the pinon nut thread depth with 2 other 8.5 rears, and I needed to tighten this one a half turn. 
Thats something I'll look out for in the future.
thanks guys

Don't even think about it. Each axle and pinion are different so you can't use one to check another. Grab hold of the front of the yoke and see if there's any movement up and down. It should have very little but it should have some. If it does then you may be fine, but don't tighten it up any further until you check everything out. If you over tighten it you will ruin the bearings and possibly the gears.

dang it!!!   how am I gonna have a reason to redo a bone stock rear if I do the job right???

lol!  I'll check when I get home tonight.  I'll also break out the book and do a little double checking and reading.  The cars not going anywhere for awhile.
