XF Wheel stud

Doctordeano · October 3, 2015

Hi All

I fitted a set of 18" Vella wheel I had painted gloss black to my red XF Sportbrake today, they look great but on the last wheel I overtightened a stud and snapped it off! The question is how hard is it to fit a new one? I know it would be calliper and disc off but will I need to take the hub off? It's the rear not the front.

Any help would be appreciated.

Thanks

PS I hope to post a few pics soon of the car and the new wheels plus the additiona stud! When fixed...

Hi Dean

If I understand correctly, is the threaded part of the stud still in the hub? If so, years and years ago, I had a similar problem. If memory serves, (and I am talking 20 plus years!) I used a stud extractor, i did this when the hubs where cold, if hot, as you know, the studs expand, and will be tight.

I sprayed the broken stud with WD40 and let it work itself around the thread for a few minutes, I then drilled a small pilot hole down the centre of the stud, I then enlarged that hole, to receive the stud extractor. It was a self threading / left hand thread which is quite important! When the stud had cooled down from the drilling, I inserted the extractor, and started it off, keeping as straight as possible, don't be tempted to use WD 40 again, if you get any of it in the hole you have just drilled, it will compress, unless you drill through the whole length of the stud.

As the extractor started to bite, it undid the broken stud.

I would just double check the info I have given, in case my memory is playing tricks! Either way I hope you get it sorted out

Regards

Hi Steve

I think the studs on the XF should just knock out on a splined shaft so when the spares arrive it shoud be a simple job. Thankfully it's not on the front hub which is more problematic as the hub needs to be removed to get to the studs so they say you have to replace the whole unit. Then you are talking hundreds for parts rather than my £20 I've spent on replacement studs and nuts. You cant buy studs new from Jaguar so I've managed to source three from a breaker who popped them off a rear hub. That will give me some spares if for an reason any more go. I didn't use force and was tightening them by hand with a standard wrench so my suspicions are someone has had tyres swapped somewhere using a windy gun and overtightened them. Or I am stronger than I think!

Just torqued the remainder this morning and some nut moved a little and some didn't so undid those and retightened them using the correct setting on my torque wrench. Just got to wait for the spares to come through and a few hours next weekend to fit and it should be resolved.

Lesson learned don't be lazy and always use a torque wrench to tighten your nuts or they might fall off! :-)

Have a good sunny Sunday everyone!...

Cheers
