REMOVAL
REMOVAL - LOWER CONTROL ARM
BUSHINGS - 4WD (LD)
(1) Remove the lower control arm (Refer to 2 -
SUSPENSION/FRONT/LOWER CONTROL ARM -
REMOVAL).
(2) Secure the control arm in a vise.
NOTE: Extreme pressure lubrication must be used
on the threaded portions of the tool. This will
increase the longevity of the tool and insure proper
operation during the removal and installation pro-
cess.
FRAME MOUNTED BUSHING
(1) Install the bushing tool 8682-3 (receiver) and
8682-4 (driver) with the threaded rod and the two
bearings as shown for the replacement of the frame
bushing (Fig. 3)
CONTROL ARM BUSHING
(1) Install bushing remover tools 8682-2 (adapter),
8682-3 (receiver) and 8682-4 (driver) with the
threaded rod and the two bearings as shown (Fig. 4)
REMOVAL - TORSION BAR CROSSMEMBER
BUSHING
(1) Remove the torsion bar cross member (Refer to
13 - FRAME & BUMPERS/FRAME/REAR CROSS-
MEMBER - REMOVAL).
(2) Secure the cross member in a vise.
NOTE: Extreme pressure lubrication must be used
on the threaded portions of the tool. This will
increase the longevity of the tool and insure proper
operation during the removal and installation pro-
cess.
(3) Install special tools 8838 threaded rod, 8835-1,
8835-4 and 8835-3 as shown in the graphic below
(Fig. 5).
(4) Press out the bushing.
