What is the torque spec for the ten nuts holding my V6 3rd to the housing? They keep working loose. The only Toyota manual I have access to, for a Tacoma, gives 54ft/lbs for the Taco V6 and 18ft/lbs for the 4 banger. The 54 feels like it's going to strip the studs long before I reach it, the 18 isn't even girly-mahn tight.

hmmm......ive never torqued them to spec, and i ran a v6 rear housing, held fine, i just did it til it 'felt' right, BUT you might try some blue loctite on the studs, or i guess you could use nyloc nuts? never thought about that.....just my $.02

I will have to say the same, I just tightened until they felt good enough. As far as 54 ft-lbs, I think that will definitely break them. Loctite would help out a lot in this situation. I did not use it but mine have not worked themselves loose. $.04 now. <IMG SRC="smilies/biggrin.gif" border="0">

I'm suprised you didn't snap the studs clean off at 54ftlbs. 18ft lbs is plenty. look at the diameter it's not much therefore it doesn't take much to get enough strech on the stud. Maybe you confused the drive shaft flange bolt torque specs as they are next to each other in the books.

It probably makes a difference too whether or not you have the 8" (electric locker) or 8.4" (open) Taco diff. The 8.4 uses 10mm studs vs. the 8's 8mm's.

Tried Loctite?

My nuts work loose sometimes too, but I haven't tried Loctite yet...

Robert, don't follow the manual, it is a misprint <IMG SRC="smilies/rolleyes.gif" border="0"> A friend of mine found out the hard way when he torqued several of his retaining nuts down that tight and pulled or twised a handful of them off. The funny thing is, Toyota knows about it and hasn't issued any kind of bulletin or correction...

I'd go with the others' sugguestions and try Loctite or maybe pot the studs with RTV before installing and tightening the nuts? Just a thought...
