Diffs

[HVAC25000]

May have been discussed and I can't find it... so...

I'm tired of my diff loosening and eating itself so I'm looking for a solution. I've actually ignored my car for a couple months just because the diffs are so much work the car is no fun.

I heard a couple months ago about putting the HB D4 diffs into the Pred. Don't remember who was talking about it, though. I think they said they were just waiting for the diffs to be released as a complete unit.

Anyone get around to trying that? Or any other diffs?

Or, has anyone gotten around to putting a standard spring setup in the stock diff? I think it should just require a washer, a longer screw, and a spring, but not having those things or a hobby store nearby, I'm not able to find out/figure it out on my own. I'm not even sure if this will fix the diff loosening, I just know that none of my other diffs come apart (except my Mi-3, which has no spring as well).


Thanks guys

are you thread locking the diff bolt?
i've never had a diff come un-done like you describe.
are they the right way round etc.?
built correctly?

i've also tried a HB One-way in the car, the driveshafts don't fit inside the outdrives, so that would be a waste of your time.

take your diffs apart, and clean everything, then rebuild as per instructions, make sure you use strong thread lock on the nut/bolt.

pretty much as andy says, ignore the superglue idea and use a good threadlock, i use the trackside solutions stuff (blue bottle) as it is really good and havent had that problem. as the diff and thrustrace balls are ceramic try using a very thin smear of grease on both rather than to pack them as i found this to be better as well, if you want a full guide as to how i build one then pm me and i will put together a how to

I had one come undone some time back, but the best idea is to stick with the Pred diffs and perfect the technique as described above. Job done.

I had the same trouble when running my pred. It was caused by dirt in the thrust race. You may get away with cleaning it and rebuilding but, if its happened a lot the thrust balls may now be mis-shaped. Not really a problem with the diff just my slack maintenance regime

i'd say from experiance use loctite 242. its around £4.00 for a 200ml bottle but it goes far.
