Hey guys,

My brother's jeep sheared a stud this morning while he was on the way to work. His rotors are seriously warped, which he thinks may have contributed to the pressure on the lug nuts. I'm wondering, though, what might be entailed with the replacement of a wheel stud?

Any ideas?

remove hub, pound out existing stud fragment (can be done with a punch or the one your replaceing it with and a 3lb sledge)... line up the new stud on the back side with the grooves, then get some grease and some heavy duty convex washers and use the lug nut to pull the stud through with the hub in a vice

advance auto carries studs for most vehicles

Cool deal. I just wanted to make sure it was do-able at the house. Didn't know what was involved.

Any other tips/tricks?

honestly that method I've only done on a trailor hub... it worked perfectly... but I'm not sure gettin a cars hub off will be nearly as easy...

I think I might have some rotor warpage myself in my WJ. A slight steering wheel shimmy when breaking at 40-70 should confirm this, right?

you can rent a wheel stud puller from AZ if you wanna be "proper"

Jeep updated the brakes on later model WJ's, earlier ones had bad problems with warping rotors.........later ones didn't seem to have the same problems as earlier ones. IIRC, it was either the 02 or 02 models that received the updated calipers

Alright, so, wheel stud puller....what else do I need for this wonderful feat? I think it sounds more difficult than it probably is...I think the hub part is what'll piss me off.

you can just pound it out w/ a hammer. use some anti-seize on the studs when you put the lugs back on. i used to shear mine off all the time for some reason, i torqued them all the same, but after i put the anti-seize on i haven't had a problem.

and wj brakes had two style calipers, akebono and teves. the teves was in 99 and the akebono was 00-later. i think the problems occured w/ the teves style, and then they switched. that was my understanding.

I don't believe you need to take the hub off. I have yet to, and I've done a countless number. You smack the old one out with a hammer, and then slide the new one in. Use greese or anti-seize on the new stud, then put four washers on that are greased, and then use the new lug nut to pull it through.

it's a little tricky with the unit bearing, but the back part of it that bolts to the knuckle is triangular, so just rotate the hub until you can manuever the stud in.

like ^ said, you don't have to take the hub off. if you do feel you need to, you'll need a 36 mm socket. i have one if it comes to that

The Teeves were May 02 and earlier. I have a May 02 model, and last year when I got the thing I had a kind thudding sound starting at around 35mph that matched speed and would disappear (or become overwhelmed with road noise) at around 65, coming from the front. I figured I would replace the calipers but when I got in there and looked the were already Akebono, I assume since my ride was a lease vehicle before is why the were fixed. Anyway, the thudding (its very quiet, most people can't really hear it) is still there, and the gyrating wheel seems to be ever so slowly getting worse. Is there any way I'll be able to tell they are warped at this stage? I assume it will be too slight to notice.

I've replaced 3-4 studs (casualty of lots of autoxing) and its not necessary to remove the hub.

^^ you're right, my bad. i do know that the 99 calipers are a little bit smaller bc i can fit them w/ 15 in rims and 3.75in. backspacing.

I have got the same issue with my 04 Grand Cherokee. I just got it a few months ago and there is a pulsating feeling in the brake when braking. I havent checked but I assume that the rotors are warped...Can anyone reccomend a good brand of rotors and calipers for replacement?
