Anyone know how to tighten the main bolt? I pulled the carpet back from the rear hatch area and used a 17mm socket. When tightening the bolt, it just seems to spin on its own axis. I am assuming that this has something to do with the fact that it is on a monoball bearing? The housing below it is circular so there would be nothing to grab onto. This is coming after installation of the JIC's and discovering clunking that came from the rear right side. I have a replacement upper mount bearing on order as well as AP rear drop links.

TIA

 

Probably have to have another person use the spanner and hold the lower body with that while you tighten.

 

This is usually done out of the car with a impact gun and a careful hand.
