the shop wouldn't do it. they said ford told them to use a special pump to suck it out and refill it, which they don't have. they said the rear crossmember gets in the way of removing the rear cover. guess I'm s-o-l for now.

That is such BS!!!  There is an access hol e in the rear subframe to access tge drain/fill hole on th e rear diff cover.   Any kinda suction pump will pull the fluid out.  Filling it, is a non issue.  Hand pump you can reill.  I went and bought another cover and made a drain plug to make fluid changes easier.

so, if anyone somewhat nearby that has done this wants to make some extra money, hit me up. I was hoping to have it done before the florida trip, but that is unlikely now.

Yes it is...Do yourself a favor....Never ever go to that shop for anything....If you can change your own oil then you can do this job...The subframe doesn't get in the way of anything!.WOW just WOW. It's mind blowing that a real shop would say this...No vcuum pump needed! A small tube of RTV and gear oil and some sockets and a ratchet......Don't ever go to that shop...They are either stupid or crooked....In either case there is never a need to go there....That's what's needed to put them out of business.

So what is the forum recommended lube for the rear diff and how much. My rear whole diff end to end was replaced at 44,000 miles I have 63,500 now and want to replace with some good stuff then I will leave alone for awhile. Doing the PTU fluid this week with Amsoil severe duty, it too was replaced at 44,000. I will replace the PTU fluid every 20 or 30,000 miles...

Redline Lightweight Shockproof or SuperLightWeight Shockproof should work well for the RDU.  Also Amsoil Severe Gear.  Quantity is nearly 36 oz, IIRC.  2.4 pints.

You can actually clean out the RDU if you choose to do so since it is easy to remove the cover.  Then seal the cover back onto the RDU, allow to cure, fill with new fluid via fill hole.

bamsho has a HOWTO on installing a drain plug for the RDU if you care to do that.

A few things that might help you guys. 1) They make square drives that fit inside a ratchet wrench that buys you some room on the plug, and 2) as any NASCAR fan should know-take a sawzall and lop off that extra exhaust hanger that serves no purpose on our car (SHO) and hit it with some black paint.
