Ford 8.8" rebuild information.

[Ant]

Hey guys,

I have just looked in the Yukon kit and it has some yellow grease in a red container/paint brush, also I assume a little tube of assembly lube for the threads!!! I think I will order some ARP Lube which will come in handy for other jobs.

The kit has new crown-wheel bolts, I wonder if its worth fitting new carrier bearing cap bolts! My IRS is all alloy including the caps so I am a bit wary of torque settings etc as over torque may distort the cap.

Even the caps are aluminum? I don't think I knew that.

I would just reuse what you have and torque to spec.

If you're concerned about really putting some power down, you could always put in a set of ARP studs. I just installed a set on my 1990 Mustang when I switched gears.

I would like to get hold of the torque settings for the alloy IRS especially the main cap carrier bolts. I gather the other settings maybe the same as the cast 8.8, but alloy may grow more .............?

Blykins,

I have purchased some studs ARP 250-3004, I see the original bolts are 70-85ftIbs, from what I can gather 70ftIbs for an alloy pumpkin, and up to 85ftIbs for a cast IRS unit. I am actually wondering what you chaps torque these studs down to with the 1/2" UNF thread on the outer end?

If anyone can contribute information on whether the Aluminium 8.8 has different setup clearances etc than a Cast iron 8.8, I would appreciate it, as all the information I have found doesnt differentiate between the two materials options!
