Big week for the car this week with a new wheel carrier, right lower control arm, rear carrier ball joint and integral links and Vanos oil line.
Turns out my clicking was actually coming from 2 (TWO!) busted sleeves in the carrier. one on the lower control arm and one on the Thrust arm.
massive thanks to @Eagle for the installation help.
some other niggles have presented themselves such as the DISA needs a rebuild and worn sway bar bushings. Parts on order!
in other project new, I have all the bits for my headlight rebuild on the Xenon’s, just need some free time to do it.
