I had some tyres fitted on saturday and the previous owner of my car had managed to cross thread two of the wheel nuts on the drivers side rear wheel. Unfortunately the tyre fitter operating the impact wrench was a little heavy handed and managed to snap the stud clean off I was just about to ask him to try a breaker bar instead too

I have a set of studs and nuts on order from the local dealer but while I'm waiting I'd like to know if anyone has any tips on changing them before I jump in at the deep end so to speak.

The car is a UK spec 1984 MK3 RX7 therefor it has the GSL-SE / Turbo Suspension all round

Cheers,

A sheared stud, isn't that called a gelding?

Have them weld another bolt on it, and try again real carfully, while applying heat and WD-40.

An "Easyout"

Your drill a smaller hole in the bolt then you thread in a "backwards" thread into it and it pulls it right out. You turn this in a counter clockwise direction to thread it in and when it bottoms out it turns the broken piece out.

This is sometimes easier said than done unfortunatlly.

so the studs on the GSL-SE type suspension are screwed into the hub I thought they were a push fit with splines from the rear of the hub ?

if they are screwed into the hub are they reverse threaded so that they do not wind out of the hub when you undo the nuts

If they are screwed into the hub I'm pretty much screwed as they would have surely unscewed before the stud sheared when it got a good bashing from an impact wrench

If the tyre shop lad did it with his power tool it's his responsibility to fix it - at least in Canada & the US.

MikeLMR

as the previous owner cross threaded the nut they are not responsable
... I've not had a proper look at the car yet ( got to remove the disk) but hopefully they will be a push fit and I can just knock the damaged studs out and pull the new ones in

MikeLMR

Right, the studs arrived today and they are really easy to change.

Step 1 Remove disk

Step 2 knock stud out of hub using precision adjusting device (big hammer)

Step 3 insert new stud and pull through hub using wheel nut and suitable spacer

Step 4 refit disk etc.

Sorted
