Please note the thread size is different on the control arm to the shaft for a tight fit to prevent control arm bushings from backing out after installation (if they were the same th thread would not be snug and would allow the bushing to back out upon suspension travel).

Please note a spacer should be made to prevent between the inner flanges of the control arm (shock tower side) to prevent crushing of the arm upon tightening of the shaft bushings. Make sure the shaft pivots freely after installation and grease before and after assembly.

For added safety you tac weld the bushing to the control arm QUICKLY Then re-grease to cool bushing.
