You'll need a new pinion nut, crush collar, bearing seal driver kit (can rent @ autozone) and three jaw puller (can rent @ autozone) in addition to the seal. Also, make sure you reference the pinion flange orientation relative to the pinion shaft before removing the nut/flange.Oh Wow, okay.
Do you know if I will need to buy the companion flange as well as the pinion seal?
Thanks for the info. More is better. I've been in communication with people that have worked on the rearend and one of my questions was about the crush sleeve, here is what they said:You'll need a new pinion nut, crush collar, bearing seal driver kit (can rent @ autozone) and three jaw puller (can rent @ autozone) in addition to the seal. Also, make sure you reference the pinion flange orientation relative to the pinion shaft before removing the nut/flange.
You'll need a beam style torque to measure turning torque to get the preload on the pinion nut within spec. You'll need a pinion flange tool to hold the pinion flange while you torque down the pinion nut to spec.
I used this one:
Pinion Flange Tool
Oh, no new companion flange is needed.

Good info. I'm pretty much a one-man-band. I can get an extra set of hands and even two minds but no one more experienced then myself.That's correct. You don't need a crush sleeve to replace just the seal. Use a center punch to mark nut in relation to the shaft. Remove the flange and seal and check the condition of the flange sealing surface. Clean the splines and threaded area of the shaft. Have someone familiar with seal installation do the actual seal install. Put the flange back on with silicone sealant on the outer part of the splines, apply a bit more silicone to the area behind the nut and washer. Apply red loc-tite (a drop) to the threads and tighten nut no more than your center punch marks. Don't accidentally over tighten the nut.
I usually count how many complete turns it takes to remove the nut so there's no guessing. I've never had a problem doing it this way.
Oh okay. It sounded as if you were saying I would have to replace. I will do what I can Not to screw it up cuz it looks like the crush sleeve is only accessible from the inside so...The crush collar is a backup in case you screw up the existing one. It's easier to have it in hand rather than trying to find one locally (or wait a few days to get via mail).
Your choice...

I've added the parts list up to ring & pinion.I've haven't worked on one of these new units yet, but have been into many different ones over the years. I'd like to offer more help, but that parts break down you posted does not have the parts list that goes along with it. Each numbered item on the pic should have a numbered list with a brief description of what each part is.
