Most of the advice has been correct. The two part outside compressors do not work (I have a Snap-On unit and it slips before the spring is fully compressed). Rent the unit from Performance Products, IMO. The front springs are 18+ inches long and want to bend as you compress them. The M/B Factory clone that Performance rents works very, very good. My other comment is: Don't use silicones to lube any bushing of this type. The bushing works by twisting; the I.D. is locked down by the compression the bolt provides and the O.D. is locked in the control arm. Silicones will allow the bushing to slip in the control arm. Use dish soap or a non-silicone rubber dressing. Even bar soap can be made into a paste that will work. I know. I made that mistake on the trailing arm bushings on my 114 chassis 250. I ended up redoing the job.
