rear hub nut removal
i am trying to dismantle the back end off an xr4x4. Ive got most of the torx things off, not too hard in the end except my t40 twisted slightly - its
gonna be fun getting the last 12 off!
anyways, it obviously an ABS disc hub. Am i right in thinking that to get it off the rear suspension arm i need to undo the hub nut? and if so, anyone
know what size socket does that? Any tips on how to do it, ive got a long bar and an impact wrench... 
cheers guys.

I'm pretty sure the hub nut is 41mm and the nearside is lefthand thread,once the nut and washer are off the hub should with some pursuasion pull
apart from the carrier.
Unfortunatly when my old pc crashed i lost all the pics of the hubs apart showing all the bearing/seals and splines,i'm sure there is a good pic
in the haynes manual showing this though

It is 41mm and you will need a very long bar if you want to take it off bu hand.

if the haynes manual describes it as 'extremely tight', you can be sure its gonna be a twat to get off...  and its not attached to
anything except loosely to the trailing arm. bugger.
anyways, thanks for the tip guys.

Problem will probably holding the hubs in place if they are no longer on the car - not easy stopping the hub turning even with the weight of a Sierra
holding it to the ground!

I have done this a few times, and the best way I have found is the get the whole arm onto a workbench (with a strong vice attached!) and clamp the hub
flange in the vice with two of the wheelstuds resting against the top edge of the vice. Then use your impact wrench to undo the nut (it is indeed
41mm)

PS if that method fails, then I resort to very carefully grinding through the nut, without damaging the threads of the splindle, until it surrenders
it's grip.

This is what I did. I used a scrap brake disc and scrap steel, a short pole and a 9ft Scaffold pole. I need a better 1/2" bar

Joel, I have the correct socket and a large bar. I'm in Leeds 17 as well if you want to borrow it.

I did mine kinda like geoff but i had the other side of the hub locked up,it was more luck than anything else as i had a piece of steel the right
shape that could be bolted on where the drive shaft fits.

Joel,
What with you storing the European Sierra Running Gear Mountain I'm susprised you haven't done one of these before!
Just grind off the Torx bolts (replace with 10p a piece 12.9grade socket head caps). And take the hubs to a garage with a good air gun and get them to
take them off.
HTH,
James

hey, im in leeds 17 too!!!! u2u sent.
James, ive got most of the torx things off, in fact all on one side, but the thing is still stuck on the suspension arm? it goes through a small hole,
where the ABS sensor is, and has a large piece on either side - the wheel mounting face on one side and the driveshaft face on the other have i got
something muddled?
LMAO about the european stockpile

That's certainly confused me a little! I've only done the one though and it was 18mths ago.
Got a picture?
Cheers,

Some sierras don't have a lefthand threaded hub nut depends on age and type of back end that's what my Haynes manual says anyway
Cheers

aye, got them off in the end - thanks andy! turns out we even have a few common friends!
the end of the thread was visable on both - but even though we had it worked out, we still spent a few mins tightening the left handed one!!
funny how it blags you even when you expect it.
as it happens, its an easy job with the right tools
James, sorry no picture, but it did come in two in the end. i hammered on the end of the threaded bit, and off popped the shmia.
