broken wheel studs

[sportscar]

hi all.
         today i wanted to change the wheels on my car as i bought some new tyres and the wheel brace snapped the studs clean off
what is some way to avoid this ? grease the studs? the car is a 1750
Do i have to change the whole axle now?

Let me guess, it was the studs on the left hand side?  Which are quite likely to be left hand thread on that car, which means that you were actually doing them up instead of undoing them.

hi i know they are but i think it's so long since i have taken them off i think they may have seized

New studs are a snap to fit.

Is it front or rear?  Use a rattle gun to get the other off, it should save you shearing them off.

Yes, a touch of grease on the threads is a good idea.

Then use a torque wrench to do them up.

Cheers

Easiest job in the book. The studs just punch out backwards, and if you only need a right hand thread stud they are readily available at Bursons or ABS brakes. Left hand thread type on the other hand might be a little harded to get. What ever you do don't mix 'em up on the same axle. Very confusing. Also don't be drawn in to secondhand left hand studs, as they usually become damaged or weak during the removal process. Often as a result of broken left hand thread studs, most owners opt to change all the left hand studs with normal threrads, as the full set of 8 are not very expensive. If you are going this way, it is best to remove the rear axle and the front rotor hub. It is not that hard, just a little time consuming.

Hmmm.... Not that common for studs to seize and snap, suggests that the wheels have been overtightened a few times and weakened the studs....  As far as replacement, others have given you good tips.... Personally if replacing a stud on the LH side, I'd change the lot to RH thread as Gary said.

Some years ago I replaced the standard diff (disc to disc) on my 1750 with a limited slip one from a 2000GTV.
The studs on the later models are all RH thread, so that left me with just one wheel that had LH thread studs (front LH wheel). I got sick of it about 18 months ago and when I replaced the front wheel bearings, I pressed out the old LH thread studs and replaced them with RH studs. Easy job and I haven't regretted it. I think old Valiants also had this LH/RH thread wheel nut mix.

I usually give the studs a light squirt with WD40 prior to replacing the wheel nuts. Torque to about 60Nm (~45ftlb).

Yours must have been done up bloody, bloody tight to snap off like that .....

I never tend to use a rattle gun to do up wheel nuts, just a good nip with the wheel brace going diagonally across each nut at a time will ensure that the studs are not over torqued and more importantly, it will also be able to be undone using that same wheel brace when it is most important, ie: a flat tyre in the worst possible spot!

wow tim you must have arms like arnold schwatzeneger to of broken studs hey mate ive just changed my rotors and i changed all my left hand thread to right hand if you need a l/h stud just let me know your address and i will pop one in the mail to you gratis how good is that cheers mario

oh and if your removing the rear studs you will have to pull the axel unscrew the bearing retainer pull the bearing to remove the handbrake asembly then knock out the old stud and hammer in the new one,a shop press is most usefull for these operations if you havent done already get chummy with a local mechanic shout him a capuchino or something best of luck
