Does anyone happen to know the spanner size required for the front hub on a sierra? I want to buy a spanner on the way home at Halfords but forgot to look up the size!

thanks,
Rich.

If you want to buy it in a 1/2" drive size it's a special so it should be labelled as a Sierra hub spanner. The same size fits the rear nuts as well. 41mm if you are buying a 3/4" drive but it will cost 3 times as much.

if its like the rear ones, hlfords do a socket specially labelled for sierra hub nuts.

Its tightened to gadzillion lb foot.

you need a breaker bar or a tube over your std wrench.

BEWARE that one side has an opposite thread, and the rears at least are nylocks

If you need a 41mm socket you are welcome to borrow mine if you want Rich.

One of those sockets that you rarely need. Are the hubs still on the car? If not you may find them a real b1tch to remove.

Cheers

If its as tight as the rear hub nuts are, as said at 1 gadzilloin lb/ft of torque you might have a job finding 1/2 socket man enough.

I ended up borrowing a Tractor 3/4" socket set and a 8 ft scaffold pole. Still bloody dangerous though.

I did it with a 1/2 socket and a 2ft breaker bar.

bar cost 20 quid from halfords, but you can undo almost anything with it.

cept perhaps Kylies undies

Steve,
Yeah I got one of those Halfords breaker bars and I think it says on it that it is rated to 450lbft or so which should make it practically unbreakable unless you use a seriously long bit of tubing over it or are very heavy/strong. I weight about 12 stones so I can happily jump on the end (336lbft) without worrying about busting it.

By the way, are the rear hub nuts reuseable or should they be renewed?

Cheers,
Craig.

From what I am reading sounds like it may be better to leave well alone, they sound fine so I might just clean them up and paint them! Just thought it may be nice to replace the bearings.

Jim, you have a good point about them not being on the car as I could well end up ripping the vice off the bench!!!

The fronts are not as tight as the rears. It gives a high torque figure for them in the manual but if you try to achieve this the wheels will not turn.

So does my grandson's pushchair. It's not F1 technology, it's common sense.

We bought a 41mm impact socket and took the removed hub/trailing arm assemblies to a friendly local garage who used their air wrench on em for free.
They wouldn't budge with the breaker bar.
James I believe mentioned that when he had his done by a garage they needed to set the wrench to 500lbft!

had mine done at a local garage with an air wrench, the guy wouldn't take any money off me either. Just remember to ask nicely!!
