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.
