Was changing brakes on my car last weekend in 15 degree weather and ended up snapping two of my lug nut studs when (Over)torquing them putting the wheel back on. I cannot figure out for the life of me how to replace these, the wheel hub does not have any clearance to pop them out and put in new ones. Im attaching some pics so everyone can see. Am I going to have to replace the wheel hub, and if so, how? I cant seem to remove it from the axle, does it just pull off? Also, I cannot seem to find the correct replacement hub anywhere. This is for the front driver side wheel on 3.0 AWD SC 2013 XF.

Can use some serious help guys!

 

Yikes! looks like a new hub and bearing for sure. Jag does sell them, here's a link for one,

https://jaguarmerriamparts.com/parts...0%26%20bearing

Unfortunately i dont have a manual for an AWD version that says how it's done, but i imagine someone on here does. Good Luck!

 

Can you make a picture from the rear of the hub?

 

Yep, you will need a new hub and bearing because you have the AWD version.


This is going to require the bearing and hub pressed out - so you'll need access to a hydraulic press.


Procedure listed below is for 2013 XF AWD. Also it appears in Topix that the wheel bearing is directional - meaning it has to be installed a certain way, otherwise the wheel speed sensor wont read, and you'll get ABS code. You'll need to make sure it's put in correctly - make note of how it comes out.

wtf? there is seriously NO service notch to bang out a single stud and replace it?

 

I mean.. yeah. take a bunch of pictures of the back of that hub. I just cant believe there is not a place that the hub can be rotated to that would allow the stud to be punched out.
Studs break all the time.

 

Pretty sure it can't be done.
Have a close look at the first pic in post #4 above, the hub is bolted to the knuckle in such a way that there is absolutely no access to the rear of the hub where the studs are. The only way is to completely remove the hub from the car.

 

Thank you all for the replies and input. Unfortunately, after contacting Jaguar, I was told that replacement studs were not available for my vehicle. And the only way to fix was to replace the hub and bearing. What a costly mistake. Ended up taking it in and having them do the work as I didn't have any of the special tools needed to get the hub off.

 

You can see it rather well here:

If you can find the right stud, it can be done imho

 

You can buy studs from aftermarket companies like ARP. Figure out the thread size and look up stud options.

On the S-Type and possibly the early XF's they have an access hole in the suspension arm:

https://jec.org.uk/forums/viewtopic.php?t=8716

It's hard to tell from the pictures if you have any room behind the hub. We need a picture from the side/behind the hub. If the hub is pressed in remove the arm and have shop press the hub out. Swap in a new stud (if you can find an afermarket option) or a new hub and reassemble.

Here is a possible stud option in the UK: https://www.autoreservejaguar.com/be...heel-stud.html

 

Looking at the video in post #9, especially from the 6 minute 42 second mark, I can't see any way of removing any of the studs with the hub mounted to the car, there is simply no room no matter where you rotate the hub to. Remembering that you need enough room behind the hub for the remaining bit of stud to come all the way out, and even more importantly you need enough room to fit the entire length of a new stud before you can get it in.
Also, the video shows a RWD XFS and not an AWD one like the OP has, and I'm guessing there is even less room behind the AWD hub.

 

I have just looked at a thread where a member had a broken stud on an XK and apparently a late model Ford Thunderbird has exactly the same lugs as the XK , he successfully replaced the stud which cost him $4.58 , what are the chances that an XF has the same studs as an XK ? would have to be worth looking into to save some major $$$.

 

So Stud can be replaced, (but needs to be found) and not in situ unfortunately...
Still I think it is possible to save some pennies on hardware cost :-)
This is only interesting if you can do the work yourself and have shop press.

 

I feel your pain. That seems to be a ton of work just to replace a broken stud! It makes you think back to the "good old days" when cars were so much simpler. I've replaced studs in the past on old school cars and all that was need was a hammer and three minutes.

I don't doubt for a minute that the designers are aware of the fact that some otherwise simple jobs would become major projects, thanks to their design/assembly. Why would they bother to make it easier for the owner when the only other alternative is to keep their parts department and main dealer "mechanics" in work?

 

Technically not difficult as the wheel hub and bearing assembly (item 9) only needs to be removed and not dismantled.


(click on the image to enlarge it)

There is then clearance to drive out the broken stud and fit a replacement.

The problem is Jaguar consider most suspension items AND the wheel hub bearing assembly to be non serviceable items. Dealers will only fit replacements and will not repair sub assemblies. Parts such as studs for the wheel hub and bushes for suspension arms are not available from Jaguar.

Here in the UK, some aftermarket suppliers have recognised the lunacy and opportunity this provides and are starting to offer parts or exchange assemblies.

It should be possible to source replacement studs from an after-market supplier.
Maybe an auto parts store, maybe a hardware store, maybe a "nuts and bolts" specialist.
I have broken (well not me, ham fisted gorillas posing as mechanics!) a couple of the studs on the wheel spacers I have fitted to all my Jags, and I found replacement studs immediately at one of the large auto parts stores here in Oz (Repco). It was a fairly easy job to hammer out the broken stud and insert the new one, especially as each new one came with a nice big 21 mm open ended nut that was perfect for pulling the new stud in nice and tight.
You need M12x1.5, and the studs I got have 8 and 340 imprinted on the head.
Of course, even though they worked perfectly to replace the broken studs in my spacers, they may not be exactly correct to replace OEM studs in the hub, but worth a try I reckon. What I did was to take the spacer into a Repco shop and ask them to find an exact match for the studs, and they did, so if you can get the hub off take it to an appropriate store and do the same. Even better if you can hammer out the remains of the broken stud first so they can see/check the "fluting" on the head of the stud which locks it in place. Also, about a year ago, I saw either an eBay ad or an AliExpress listing (can't remember which now!) for an OEM Jaguar wheel stud (all the same across S Type, XF, XJ, XK, F-Type etc) but it has since disappeared, so it may be worth checking again for one.
