Stripped threads on rear trailing arm pocket

[Nate047]

I have a problem, stripped out threads for one of my rear trailing arm pockets. When I was disassembling the car, one of the bolts just like, fell out. 😐🤦🏻♂️

My thoughts were, maybe this can be addressed with a new thread insert, to avoid cutting out the whole pocket and putting a new/used partial panel in. Thoughts…? I found a highly regarded alignment shop who also suggested trying this as a viable option. What do we think about that?

Thought that they would recommend a Timesert.

I have new rear trailing arms pockets if you want

If you plan to track the car, I would put new one and weld the perimeter also

Ugh...I was prepping to weld the pockets, took a look and realized I really should drop the gas tank.

If only the threads are stripped but surrounding not rotted, then I would try to install a Timesert. What do you see -- crossed threads or overtorqued and stripped?

I'd choose a timesert over a helicoil as well. Those bolts see a lot of fastening/unfastening cycles.

Don't track the car without full confidence on RTAB pocket integrity.

Alrighty thank you guys. It sounds like the RTAB pocket reinforcement is optional/advisable for certain cars but not absolutely required. I think I'm going to go with the timesert option for now so I can have the car drivable. I would consider doing the reinforcement in the not too distant future as I have another repair that needs to happen in that general area.

Gt4 do you still have the trailing arm pockets for sale?

If you look in the catalog for the Z4, you can find the pockets for sale individually, they are the same as on the E46.

bmwfnatic really appreciated, thank you. I wasn’t aware of that.
