it attaches to both the front and rear mounts. Do not
tighten at this point. Repeat procedure on the passenger
side.

bushings and (4) S10239 sleeves from hardware bag

upper control arms. Special note: Make sure to use a fair
amount of lithium or moly base grease before installing
the new bushings and sleeves into the control arms.
This will increase the life of the bushing as well as help
prevent squeaking.
