11. Turn the steering wheel to make sure there is no bind in the U-joints. The steering should be smooth.
Readjust the U-joints if necessary to prevent any binding.
12. Sit in the car and adjust the steering wheel to desired height by adding washers under the upper pillow
block.
ATTENTION: Use caution when working with the rear end assembly, it is heavy. If using a complete
kit, do not forget to install the axle breather vent on top of the passenger side axle tube.
TOOLS: 15mm, 18mm and ⅝" sockets, ¾", ⅝" combination wrenches, ½" drill bit, drill, floor jack.
PARTS: Rear-end assembly with quad shocks, rear control arm bolts, flexible brake line mounting
bracket, rear traction-lock brackets/fasteners (FFR# 10885).
1. If not already done, fill the axle with gear oil. See Appendix I for specifications and capacities.
2. Position the brackets on the rear end with the bolts provided (the two short bolts go on the sides).
Attach the lower shock bracket through the traction lock bracket at the stock location.
3. Tighten the two short bolts. Torque to Ford Specs 75-95 Nm (55-70 lbft).
4. Attach the lower control arms loosely to the brackets on the axle using the bolt provided.
Note: The lower bolt holes provide more traction than the upper holes.
5. If not already on the axle, attach the Mustang upper rear control arms loosely to the rear end.
6. Attach the vertical shocks to the axle brackets. Insert the bolts from the inside out. Do not tighten the
bolts yet.
7. If using the Mustang springs, hold the spring perches up to the frame so the vertical perch mount is in
