Couple of days back I took my 2012 TL (FWD) for tire rotation. Mechanic told me that 2 out of 5 wheel lug studs were "slipping" little bit in rear passenger wheel. He showed me while torquing and 2 of the lugs always rotated little bit more every time, before wrench clicking.
This makes me feel that 2 of the lug studs may need replacement on that one wheel.
What do you guys think is happening here and potential solution?
Thanks.

Stripped studs from too much many impact wrench ons. Replace studs

I think he was upselling you...
I mean, I've "heard" of bolts stretching from being overtorqued, but loss of structural integrity?

Have you ever torqued something down that is held down by 3 or 4 screws or bolts? You do one side, think it's tight, then hit the next bolt and the previous one has another half turn in it and so on...
Stripped would just spin and spin and then probably not be able to back back out.

I'd leave well enough alone.

^since we cant physically check....all we have is OP's written word.

after re-reading the original post, it does sound like dude didnt tighten all the way????? then finally "clicked"

i'm confused.

Well, it didn't sound to me like it was just spinning freely from the way I read it.
Also, I know this from putting spacers on because I always do 7...I do 5 in a star pattern and the first 2 I did, I redo and they always go a little clickety clicky click more.

To clarify again, only these 2 studs slip every time I tighten them little bit, by few degrees, before torque wrench clicks. Other 3 studs click right away. The guy who did tire rotation made a big deal out of this (due to liability issues ???), but to be fair he asked me to take it to a mechanic for a fix.

I spoke to Acura service dept and they said that in most case they even have to replace ball bearing as its not easy to reach these studs from behind without first removing ball bearing, which most often can't be removed due rust etc. But I am going to make it very clear to them that I do not intend to replace anything else other than these slipping studs. I have an appointment for tomorrow afternoon. Will let you all know how it goes.

Forgot to thank you all for your responses. Thanks.

Sure thing, Ganja...
before you do that, why don't you try swapping the lug nuts around first...might just be some partially stripped out lug nuts and that would be a hell of a lot cheaper and easier to replace.

Also, if you're mechanically inclined...
it's possible to do it yourself with the right tools without needing to press a new bearing in.

of course they're going to say that! it's much easier to install the entire wheel bearing with studs than just the studs themselves.. and more expensive to boot!

ganju420

Good idea. I am certainly try swapping the lug nuts.
Thanks!

I thought I should share the outcome of my visit to Acura Technician. Even though couple of lug studs were slipping slightly, apparently the problem lied some place else. It seems earlier owner changed break rotors and pads himself and in the process he put the 2 retaining screws for rotor in wrong holes. This made those 2 screws to stick out, which in turn caused wheels to not tighten completely. That seems to have fixed the issue.

lmao, so he ran the 2 screws into the slot used to push the rotors off the hub! WTF...
so wheels wouldn't seat completely!

Glad it's resolved and thanks for letting us know outcome!
