Inspect shock bushings for wear and deterioration.
If new bushings are needed, replace with standard
5/8” ID hourglass type bushings before installing
Bar Pin Eliminators.
2. MOUNT BAR PIN ELIMINATOR TO
SHOCK ABSORBER
Apply a thin coating of wheel bearing grease to
the Cross Pin (A).
Insert Cross Pin (A) through upper bushing of
shock absorber.
Slide remaining Mounting Block (B) onto opposite
end of Cross Pin (A), making sure bolt and roll pin
holes are correctly positioned.
Determine whether rear upper shock mounting
holes in chassis require metric or standard bolts.
HINT: Depending on the vehicle, the rear shocks
mount to the chassis with either metric or standard
bolts. Both types of bolts are supplied with the Bar
Pin Eliminators.
Place a Split Washer (F) on each of the appropri-
ate Cap Bolts (D or E).
Position Bar Pin Eliminator on mounting surface of
chassis. Insert Cap Bolts through mounting blocks
and thread into original shock mounting holes.
HINT: Mounting Blocks of Bar Pin Eliminator must
lay completely at against mounting surface of

Using a torque wrench, tighten mounting bolts to
25-35 ft-lbs.

service manual instructions.

IMPORTANT: This product is designed to preload
the shock absorber bushings for maximum performance and longevity. Therefore, you should
nd it necessary to compress the bushing approximately 1/16” to 1/8” before the mounting
bolts and/or roll pins can be inserted.
If you are able to install the mounting block without compressing the shock bushing, insert a SAE
5/8” at washer (not supplied) between the bushing and Mounting Block to ensure proper bushing
preload.
Squeeze Mounting Blocks together to compress
the shock absorber bushing until bolt and roll pin
holes align. HINT: A bench vice or C-clamp is useful for compressing shock absorber bushing.
Tap the 1/8” Roll Pin (C) through Mounting Block
(B) and into corresponding hole in Cross Pin (A).
3. RE-INSTALL SHOCK ABSORBERS
Clean any dirt or debris from the upper shock
mounting surface on chassis. HINT: A sanding or
grinding wheel is useful for removing any stubborn
material.
