Sheared Stud
 

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. :confused: Unfortunately the tyre fitter operating the impact wrench was a little heavy handed and managed to snap the stud clean off :mad: 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

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.:confused:

so the studs on the GSL-SE type suspension are screwed into the hub :confused: 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 :confused:

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.

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

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

It's "Precision calibrated adjusting whackometer" [whackOMeter,not whackoMETER] :)

thanks Mantis ... wouldn't want to break my whackoMETER ... most useful in locating fellow 1st gen owners I find :D

:rolleyes: :crackup: :rofl:
