Title: hub nuts
Post by: dhla40 on 11 November, 2010, 02:54:07 PM
Having broken two 1/2 inch drives and before I buy a 3/4 bar can someone please confirm that the hub nuts on a S2 are normal right hand thread :-[

If they are that tight may I suggest that, once you've  managed to undo them, you have a very close look at the studs. There is a chance that they have stretched under the possible excessive applied torque. It is not unknown !!! If they appear stretched it may be necessary to replace them. Have you recently had new tyres or a puncture repaired ??  It may be that they have been over-torqued by the fitter and a visit may  get you some recompense.

Good luck with it.

Just re-read your post, its the hub nut not the wheel nuts !!!!!!!  Sorry, my first response is wholly irrelevant.

But still good luck !!

my difficulty is one of getting my borrowed [thanks John Day]  hubnut tool to get a sufficient grip on the nut.if anyone has tech details of the type of tool which is secured in position by means of a bracket which is then fastened to the wheel nut/bolt threads depending on series of car i can have the necessary tools made by a friend.what i had in mind was a collar welded around the tool and a round plate with a central hole to slide over the tool .the tool then being pressed onto the hubnut by pressure from the wheel nuts/bolts which would pass through 2 or 4 suitable drillings near the circumference of the round plate.just a thought ,perhaps a scrap disc/hub could be modified into such a device with some machining,or at least as a template.richard

Richard/All

I use a two jaw puller from the hub which bears onto the centerline of the tool/tommy bar (depending on tool config). this keeps the tool located and even with a bit pressure along the axel line from the puller, I can then put a scaffold pole on the tool extension and free the nut.

The hub nut tool I am using is made from a 36mm socket that I modified with a hacksaw and is held in place using an old hub puller bolted to the wheel. It is strong enough to break a 1/2 inch drive but I will see how it deals with a 3/4 bar, if that fails I will drill the nut off, anyone know how much new nuts are?

hi Tim,at 20 pounds each i am grateful to have found my spare ones in my boxes of stuff.modification of nut design sounds worth a try.if possible could you explain the 'stakeable' evolution design.best regards richard
