Mistake installing LCA, need part - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

I need a replacement part but don't even know what it is called.

The front lower control arm and the lower arm support plate both slide onto the same bolt or threaded rod that sticks down under the front of the vehicle on each side. Is it a bolt or a threaded rod (cannot get to other end)? What is it called / what is the part number? How do you remove/replace it?

Was asked for a picture so I'll try to add it here:

... failed so here's a link.

Take a picture. It would make it a lot easier to help you.

THIS!

It is a stud that unscrews from the body using a 15mm ring spanner or deep socket. Once the arm is off you will see the 15mm Hex so you can undo it.

The threads are M14 x 1.5 both ends.

Thanks, Nigelr32. I got it out and it doesn't look bent. That's bad because that means the hole is bent.

Now we have established which piece of hardware you're referring to. What is the problem you're having with it?

Sounds like it doesn't line back up with the mounting holes on the LCA?

Basically the hole in the frame that that bolt screws into was bent. With it bent the lower arm support plate cannot be reinstalled. A large bar slipped over the bolt and application of force to bend back to verticle seems to have fixed it.
Then reassemble, correctly this time. The incorrect install was my fault and the correct way to install is obvious in hind sight. After market kits should come with instructions, no matter how obvious installation should be.

Just got it aligned again so all is well.

Glad you got it sorted out. What were you installing, if you dont mind me asking?

I installed adjustable front lower control arms from RacerX Fabrication. Very nice part. There are a selection of colors if you want to pay extra for anodizing. It goes under the car so that's just silly. I got orange.
