Way over torqued lugs

[Asiah119]

I've read that over torquing could lead to brake issues. But I don't understand why. I know it's very dangerous in terms of lugs snapping, though. It distorts them to a point of failure.

My mechanic that didn't do this told me that its uneven torquing, not just over torqueing. With over I believe that it doesn't give the rotor the room that it needs to expand as it heats up. When the lugs aren't torqued evenly, it compounds the problem because the rotor cant expand evenly. At least, that's what makes sense to me.

Has anyone had experience with needing to replace that eccentric nut to adjust rear toe?

You mean camber? Toe is adjusted by loosening the three bolts holding the trailing arm

I'm increasingly convinced of how much I need to never go back to this shop.

Incoming wall of text.

The sheet that I got post alignment has as follows for the rear (I'll try to organize it as well as possible):
Camber Initial Spec: Max/Min Final
Left -1.5 -2.3/-1.8 -0.5
Right -2.2 -2.3/-1.8 -2.2

Toe
Left -0.10 0.10/0.20 0.05
Right .40 0.10/0.20 0.15


So my left side is all jacked up still. When I picked the car up, they only said that it wouldn't go into spec and cited the eccentric bolt on the lower control arm as turning but not effecting the wheel angle. They didn't offer anything on actually fixing it.

They too lazy to adjust toe? Three bolts. Tap in spec. Tighten.

For camber. They have to turn the inner bolt not just the nut

I HATE LAZY techs

What I don't get is that they adjusted the Left camber, and the Right toe. It's not like they didnt know how. This is why I'm on the look out for a different shop.

Im getting close to just going to the dealership, I'll pay through the nose, but they'll at least, you know, do the job that I'm paying for.

There is no eccentric bolt on the lower control arm. Lived in a shop to long and why if I can't do it I take it to the dealer.

I'm on my phone, so I can't link it, but realoem lists an eccentric on the lower control arm.

Edit: Here is the realoem diagram: Part number 10

Oopppps, I thought you were talking front control arm, not rear. You may have worn trailing arm bushings, a very common problem with rear wheel alignment

Well, I scheduled a visit with bmw for an alignment. At least I'll be able to tell them to get the values closer to equal. And they'll actually bother with looking into why, if it is the case, the camber and toe didn't get moved. I still haven't had a chance to really get the brakes hot and see if they get back into shape, I'll leave that rage for another day.
