Front Monoball bearing replacement

Christian (Colt) kindly supplied me with the bearings he aquired here are some pics of fitment .
Picture shows the original bearing on the left and the stronger replacement on the right.

In order to drop the shock (damper) low enough to get the monoball tiop mount out, i removed the anti roll bar drop link

The bearing is then pressed out and a new one one pressed in. A little heat is useful (not too much though !) Picture shows the mount lying down ready for the bearing to be pressed out. Anew bearing would be pressed in from the top. The new bearing is already fitted in this shot. I forgot to take the photo's

You will want to support the control arm with a trolley jack when letting the shock down. With my KW's the front didn't need spring compressors. The standard RS shocks might need them. Re-fit is a reverse proceedure. Torque the Plug nut to 180 Nm . You'll need a 50mm socket (from memory). When looking at the old bearing there was more play than i had imagined. But front left takes a lot of the cornering forces on clockwise tracks.
Not that I am expecting anyone on here to be likely to attempt this themselves. But hopefully it gives an idea of what is required.
I would recommend doing this when doing a suspension refresh. Rather than as a separate activity. It saves doubling up your / your tech's work.
