Are the threads for the Sierra rear hub nuts handed? There isn't much thread showing past the nut for me to tell.

Also, are the nuts difficult to remove? I haven't tried yet (due to not knowing which way they unscrew - as above) and I haven't got a socket or spanner that big (yet!)

BTW the hubs are off a Ghia with ABS and Lobro joints, similar to 4x4 I believe.

Any help/advice much appreciated.

yes they are.
not sure which is which

Yes they are handed, although I believe some early ones are the same... Yes they are difficult to remove... I did'nt as I can't see the point, as if its not bust why fix it? Decided not to make more work for myself...

They are handed, they always tighten towards the front of the car.

Mike

Yes they unscrew in the opposite direction to the wheel normally turning, as do the front sierra hub nuts. They are also extremely tight and best loosened when on the donor. If all else fails, grind a slot down the side and they will release with a bang, cheap to replace.



check how many replied to that!! we're all very busy this Friday afternoon

42mm IIRC in case you were wondering

As above. Slacken them off by pulling down towards the rear of the car. I have an impact socket and 3/4" breaker bar plus a 3ft scaffold pole to do the job.

Plenty of penetrating oil will cerainly help

I got the hubs undone off the car by using a cunning tool fansioned out of some angle-iron. Details here:

Don't ask why I used it - probably because it was the closes thing to hand at the time but I managed to snap my torque wrench getting mine off! Ended up using an 8ft scaffolding pole and plenty of thread release!

bilbo, thanks for the idea, i have been with the rear right after finding that it waggles a bit more than it should, tried the breaker bar and scaffold and just pulled the car backwards, soon as the rain stops i will make up the angle iron and have a go.

That tools identical to mine bilbo.

i parked our transit on top to stop it moving when undoing.

If you havent got one already, buy yourself a breaker bar at least 2 feet long.
I wish I'd bought one 20 years ago, it's amazing how a nice steady pull on a nut/bolt works better than impact wrenches, hammer and chisel long poles attached to sockets etc
I use mine just because it's easy on almost everthing, a0part from when things need to be carefully torqued back up

No need at least for the push in shafts
(I don't know about bolt on ones), whole thing comes though the trailing arm once the 4 bolts holding the hub carrier are undone... No need to touch the big nut... Nice and simple design..
