Note: The bushings supplied with these arms are designed to be used with the original differential bushing shells. Do
not press out bushing shells.
1. Remove rubber and the inner sleeve from outer bushing shells.
2. Clean original shells thoroughly.
3. Using special pre-lube teflon grease, lube the I.D. and flange of the O.E. bushing shell.
4. Lightly grease O.D. and I.D. of polyurethane bushing.
5. Install bushing into shell.
6. Grease O.D. of steel sleeve and install into bushing.
7. Install thrust bushing.
Edelbrock Adjustable Trailing Arms are fully assembled, greased, and ready to install.
1. Install new trailing arms with the grease fittings facing down, locating the front bolt first.
2. Place one drop of blue Loctite™ on clean threads and torque the nut to 70 ft./lbs.
3. The trailing arm should then pivot smoothly.
4. Place a thin coat of supplied grease on the sides of the new axle housing bushings.
5. Pivot trailing arm into position over polyurethane bushing and thrust washer. Install rear bolt in same direction as
original.
6. Place one drop of blue Loctite™ on clean threads and torque the nut to 70 ft./lbs.
7. Although Edelbrock Trailing Arms are pre-lubed, you may want to finish your installation by lubing the front bushings
with a greasegun. Be sure to replace the dust caps on the Zerk fittings to prevent dirt and corrosion from damaging
the fitting.
Check all nut and bolt tightness after first 10 miles.
NOTES:
1. Edelbrock Adjustable Trailing arms come pre-adjusted to stock length. Pinion angle can be adjusted by loosening the
jam nuts on the arms and turning the aluminum adjuster sleeve in the center of the arm. Both arms should be
adjusted evenly. A properly installed and adjusted trailing arm will have the spherical ball straight and parallel with
the ball housing. If the ball is twisted in its housing when installed, the arm could fail during suspension articulation.
After adjustment has been made, use a drop of Loctite™ on threads at jam nuts.
2. Jam nuts should be checked periodically for tightness.
3. To further enhance the handling and performance of your Mustang, check our catalog to find out more about Edelbrock
