Wheel Studs turn in hub

[arthurr]

The studs are turning in the hub when installing or removing wheels. This is happening on several studs is anyone having a similar problem and if so are you replacing studs or repairing in some other fashion?

Not heard that one before.
You could try new studs but I suspect the hole in the hub will now be oversize and they will not hold.
You may need new hubs.
If I had the same issue I would likely use a spot weld to stop it turning but could not recommend it.

Sounds like a new stud and hope that the hub isn't damaged (ie hole enlarged to much). Remember you need extra long ones.

Don't dispare to much as they are only ford granada hubs so won't be to expensive to replace if you source some 2nd hand ones.

Funny thing is when I pulled out the studs there were no matching splines/groves in the hub. It does not look like they were ever splined in the first place. I pulled out a stud that wasnt turning to make sure and that hole had no splines/groves as well.

[andygtt]

From memory the stud has the grooves/ splines and they spread and grip the hub. I think?
How did the stud look?

[arthurr]

Stud looks fine just like the other I pulled out. I will try a new stud and then tack if I need to.
Thanks for the information.

Hmmm...tacking it in place?....wouldn't that cause an imbalance on the hub/wheel possibly causing a vibration? To get your balance back, you'll have to balance the wheel/tire ON the car. Not sure how much that could affect it during normal driving, but at high speeds it could make a difference.

I think it would be too close to centre of rotation to make a noticeable difference. Plus, if each stud had a spot weld in the same place the difference would be even less.

had the same problem. groove the stud with a sharp tool from hardened steel and put it back. works fine!

Don'tknow what your hub looks like but generally speaking studs should be screwed in hand tight and bottom out on the shoulder. You could loctite them in place. Then fit the wheel and use a smidgen of copperslip on the wheel nuts. The studs shouldn't unscrew when you undo the wheel. Is there any corrosion on the wheel nut thread?

They are ford studs and so do not screw in but are knocked on and have an interference fit....

It is highly unusual for these to come loose and there must be some serious wear or damage to allow this to happen. Either that or you have the wrong studs (standard Granada type right?) Normally the splined studs are pressed in (ideally by fly press) but it can be done using an old wheel nut, some washers and a lot of grunting
I would inspect the hub & studs carefully and if damage is evident, replace them - a spot weld can only be regarded as a temporary repair (or bodge depending on your viewpoint) Don't compromise though - it's your safety at stake here.

Thanks for that, are they splined then?

Yes splined.
The hubs are Ford Granada but the studs are extra long to cope with the alloy rims.

Know the type, thanks for that.
