For Christmas my mj got new to me upper control arms and new bushings on the axle. Boy it rides smoother and way quieter now that the bolts are centered in the bushings.
It costs .50 each. 2 quarters stuck between the release knob and the little striker plate to pull it tighter. I even hot glued them together so I didn’t have to pick them up off the floor every time I opened the vents.
How high up do you need to go. I have 4 sets of the 6 ton harbor freight type. I use them the most. For when I need some space I use pipe jacks. They will get up over 3 feet.
