Brand new wheel bearing...studs snapped clean off... WHY??

[Frank Dukes]

So heres a new one for ya tee see gee. I put a new wheel bearing on my car last week Friday. Today i drive to work and feel the death whobble. I assumed it was the opposite wheel bearing as i know it needed replace also but hadnt gotten to it yet.

Soo im cruising down 20 @ 60 mph and alls well besides the wobble. I get to work and the fuckin wheel pops off as im turning into the parking lot.. all the studs are broken clean off at the bearing..i found 1 laying next to the wheel so i assume the others popped off down 20.. wtf how lucky did i get lol.

just got the car towed home and into the garage... but i need the fuckin 36 mm to get it off that i rented not bought. looks like the bikes coming outta storage for a run to the store for a 36mm impact socket..


Why TCG? Discuss. Moog wheel bearing from advance btw.

To me it sounds like the lugs weren't tightened

I've had it happen at work when someone tried playing mechanic when I wasn't here.

 

[Frank Dukes]

they were impacted on... i suppose its possible but fuck.. i really should have checked them with the breaker bar when i was done but i did not..

 

[Bob Kazamakis]

The wheel could have been offset or hung up maybe if you impacted one on at a time all the way and not snug them all by hand first

Just going by my small scale experience when studs all snap off its always been that they weren't tightened enough.


I always snug them with just the socket in a star pattern before applying any torque to them and even then I do it in steps in a star.

 

[Frank Dukes]

Yeah i'm going to assume this was what happened. I did it in a star pattern and everything went as usual I did not notice any issue and did not have a problem right away so it is quite puzzling to me is all. Either way it cost me 70 bucks and atleast a day of work now. fuck.

 

[Bob Kazamakis]

That sucks for sure. At least it happened at low speeds and not on the highway or something. Could have been much worse.

 

[EmersonHart13]

Wasn't tight. Same thing happened to my brother on the highway...

 

[Frank Dukes]

totally myself right now... gonna do both this time and apparently pay a little more attention.

 

[Euro]

Damn, that sucks! Hopefully this time that won't happen again. Try to take it back as defected

 

[Frank Dukes]

its a 3 year warranty part i shouldnt have a problem... getting ready to gear up and ride the old cycle to the local advance.. should be interesting.

 

[Euro]

Good luck! At least it's nice out.

Yep same thing happened on my 96 LaSabre. Put the tire on and tightened the nuts, dropped the car onto the ground and forgot to re-tighten them again. On my way to work the next day started breaking one by one. Had the stock wheels on with the covers so it sounded like a Maraca in there. Pulled the cover off and 3 of the 5 studs fell out.

 

[Frank Dukes]

you have any trouble getting that replaced under warranty?

For one you shouldnt be Impacting them on and trusting it. Air pressures and guns differ all the time. I always torque mine down to 100lbs. If I dont have a torque wrench then I use a breaker bar but try to feel it.

I have seen on mutiple occasions the lugs coming loose on new studs. basically the threads stretch a little and you have to retighten. I say after a hundred miles or so.

This.

Always need to re-torque after doing some driving when putting on new wheel bearings, lugs, or wheels to re-tighten for proper torque.

 

[Frank Dukes]

yeah i know better... apparently forgetting my place at the end of the job. i replaced both fronts today and used torque wrench to proper specs, etc.

all is well.

That sucks for sure. I actually bought a 36MM when I was removing the engine of my Regal. Thats probably the only time I will use it, but it is nice to know its sitting there for the off chance Ill need it.

I also didnt have an impact when taking the bearing off. I bought my breaker, 2 6" pipes, and an adapter to connect them together. Leverage FTW!

This. The wobble is almost certainly loose lug nuts.

And this!
