Oh why does the Lower control arm do this?

BAMBAMN54 · 05-23-2020, 09:41 PM

I'm installing some coilovers on my 135i and this happened when I went to bolt the LCA back. I can't figure out how to line the bolt back up with the bushing. Excuse me if this is an easy fix.

Best,
Flynn

Something like, https://www.amazon.com/Steel-Heel-Al.../dp/B0787DJ7P6

Use the punch end to push through and hold until you can push the bolt from the other side.

And actually jacking up the wheel should also pull the LCA out and help with lining the holes up.

The easiest way would be to have someone pull the knuckle out so it will align with the holes.

This.

I thread it as far as I can, then pull on the rotor face until it pops through. Just takes patience.

Can also turn the eccentric bolt through the toe.

You are almost there...just use a tapered punch to align the holes.

Got that side done! By jacking up the brake rotor safely without damaging it! Onto the drivers side I'm still working around the exhaust which is a PAIN IN THR ASS but I think I'll
Get it. I haven't even started on the fronts yet so that should be interesting!

Thanks for the help guys!

I usually disconnect it at the knuckle end to avoid having to realign the car. You should get an alignment after you finalise your ride height though

A safer jacking point is directly on the control arm just below the spring.
