08 Prius Rear Wheelstuds.

Hi "grinthock",

You'll have to remove the rear brake drum and hammer out the broken wheel stud.

Replace your new stud thru the hole, now the fun part...

Time to seat the new stud...with an oversized nut, used as a spacer, and a new lug nut, use a impact gun and tighten until the new stud is seated. Be sure to put some grease on the new stud to avoid seizing.

I've never done this with manual tools but, i'm sure it can be done.

Good Luck.

 

Well, I just have to ask how you happened to snap the stud.
Was it a bad piece of metal, Your error, and I'm asking , not to be judgmental, but just to figure out what happened to you. Maybe some other reason, I.E. you used a impact driver set too high instead of hand tightening.
I have rotated my tires myself for the last couple of times now, it's actually pretty easy. I am wondering what I should be looking out for.
Since I too have Air available, I was considering getting an impact driver myself. Hope your fix happens smoothly, I feel for ya brudder!

 

Hmm, I think that you should first unbolt the rear axle hub and bearing assembly from the beam axle (tightening torque of the four bolts is 45 ft.-lb.) Then use a press to remove the broken stud and insert the new stud (or have a machine shop do that for you.) If you feel the need to hammer out the broken stud, hopefully you will do that in such a way so that the hub and bearing are not stressed during that process.

When tightening the wheel studs, I suggest using a click torque wrench and observing the 76 ft.-lb spec. If the old stud broke under less torque than spec, I'd also like to hear about the circumstances leading up to that.

 

Very informative thread - Thanks - Also, any suggestions/hints on how to get a stubborn rear brake drum off?

Thanks

 

I use an open ended nut put on backwards, a few washers and loads of grease.
Pull the stud in as much as you can without the drum on, replace the drum and apply park brake, use the nut, washers and grease to pull stud home then remove drum and check before refitting the drum and wheel.
I use a little never seize on wheel studs and recheck the tightness of the nuts after 100km. If one is loose check again in another 100km. Do not over tighten.

 

Buy a couple of 6 mm bolts, and screw into the two threaded holes in the drum.

If this doesn't work, you may have to turn the star wheel that adjusts brake lining position, to retract the brake linings in a little.

 

I am going to have to replace one of the studs on the front driver side of my Prius. Interesting story of how mine happened: I was driving on the freeway and heard this really weird noise, pulled over and thought it was just the plastic wheel well falling down onto the wheel, so I propped it back up and kept driving. The noise kept on and got a little worse so I pulled over again. This time I shook the wheel to find out that it was completely loose! All of the lugs were only threaded on about two turns. I was able to tighten them all back down except one, which had broken off while the wheel was vibrating back and forth no doubt. I am wondering how this happened seeing as I have not changed any of my tires lately and I am sure that all of the lugs were tight. Vandalism? Who knows. Anyone ever hear of all the lugs coming loose like this or know how it could happen?

 

How about getting the driver's side front wheel hub off? Looks like I'd have to take off the center hub nut and I'm not sure yet how to.

 

You need a 30mm 12 point socket, and either an impact gun or a massive cheater bar.

 

I was rotating my tires and snapped a front wheel stud off. I was hand tightening when it happened and realized that the stud was heavily rusted so now I have two inquiries...
1.- Should I be worried that some of the other studs are rusted and on the verge of breaking? My Prius is a 2004 with 130k miles on it.
2.- Is it realistic for me to be able to replace the stud on the front wheel or should I just take it to a dealer and foot the bill?

Thanks for your help.
