quick pinion seal question

I'm finally done ignoring both my front and real pinion seals. Been leaking all winter and I'm ready to replace them. 06' D30 and D35.

Is this all I need for the rear and one for a D30 up front or do I need a nut and collar for both to? Thanks guys.

If your careful you just need the seals.

I'll probably get new pinion nuts but the question is can I reuse the crush sleeves? I'm going to crank them down to 180 ft/lbs anyone see a problem with that, that's what it says in the fsm but I'm still woried about wrecking the sleeve. I've also seen people coat the back of the seal with grease, good idea?

Also the OEM seals seem like pretty crappy rubber, any suggestions where I can order some good seals that may last a little longer?

I have always just torqued them down to 160-180 ft-lbs. according to the advice I got from Tom Wood probably ten years ago. I've seen people pack the backside of them full of grease & I dd that on my axle seals once but I have never bothered to do that on the pinion seal and they have never leaked after being replaced.

Thx guys. What am I missing here? I can't find a D30 seal for an 06' (haven't done an extensive search yet though)

Can I reuse the crush sleeve or should I buy new ones for front and back?

Stop worrying about the crush sleeve, replacing that involves removing the pinion gear shaft. A d30 seal for an '06 is the same seal as is used on a '97. '97-'06 pinion seals are same-same.

Alrighty, thx Jerry much appreciated. crush sleeve forgotten about

I guess I have one last question. I don't have an impact wrench, any tips on getting the nut off?

Getting the pinion nut off can be interesting without an impact wrench that makes it a .73 second job. You'll need a long breaker bar, no less than 2' and 30" isn't too long. Put the Jeep into 4Lo & in gear and Park so you can turn the pinion nut with the front wheels keeping the Jeep from moving too much. Block the wheels too to help keep it from moving as you remove the pinion nut. That should do it.

Once again thank Jerry. does a 12v cordless impact wrench have enough power to do the deed?

Not very likely. I wouldn't think anything less than a 19v 1/2" would have the power.
