Background: I looked in the RAVE, page 501 shows an exploded view of the front hub assembly. However it shows #12 (hub) as a single part, including the (?) wheel studs (not sure if that is the right term).

I am getting ready to do the front rotors, and noticed one of the wheel studs is stripped. I mean the threads are rounded for the first 1/2" or so and it resists any lug nut I put on it. I can thread it on, but it offers noticeable resistance.

Question 1: Are the wheel studs replaceable, or do I need a new hub assembly? I couldn't find anything about this in the RAVE. On other vehicles I've worked on, they are usually splined and have to be pressed in. Then again, those usually went straight through the brake rotor, and the hub was mounted differently...

Question 2: If the wheel studs are replaceable, will I need to have the hub off the vehicle to replace it? I am assuming yes, but I always second guess my assumptions when I'm working on a Rover.

EDIT: Here is the diagram in question.

 

What exactly do you mean by the wheel stud is stripped? You cant get the lug nut off? Or on because the threads are messed up?
Or does the lug nut just spin on the stud?

 

I mean that it is very difficult to get the lug nut back on, for that one stud only. The threads are messed up. I can force the lug nut on, but I prefer not to. All the lug nuts spin freely going on to all the other studs, it's just this one that has excessive resistance.

 

No biggie, just chase the threads with a thread chaser.
Clean them up and all will be good.

 

But if it is beyond repair... it is replaceable.

Not sure if it will clear the brake rotor, I doubt it. You'd probably have to take it apart.

 

When I changed the rotors on the Disco, I did notice the studs can be removed. The hubs will need to be separated in order to press them out. I've changed to longer race studs before (on other cars), and it is straight forward.

I too was looking for them for the Disco and found a company in the UK...here is the link..

Zeus Engineering

Good luck and hope it works out.

 

They press out.
Those longer wheel studs from Zeus are expensive and not needed on Discos, they are for different (thicker) wheels, like Wolfs.
Any of the Rover parts vendors in the US should have the correct studs.

 

Good to know. Since I am focused on Mach5, I gave up looking for longer studs.

 

Go ahead and service the wheel bearings since you will be pulling the hub. You probably need to do all 4 wheel bearings anyway unless you know they have been recently serviced.

 

Fixed it for you.
