1. Lift rear of Mustang
2. Put jack stands under rear axle
3. Remove both panhard bolts
4. Remove panhard
5. Lay the factory panhard and replacement panhard beside each other. Adjust your new panhard so it is the same length as the factory piece. You can verify this by sliding the factory bolts through the holes of both bars at the same time. Make sure the rod ends have an equal amount of threads showing. Leave the jam nuts loose.
6. Insert the aluminum bushings into the rod end and set new bar in place.
7. We intentionally undersize our aluminum bushings because many customers' brackets are pinched from the factory. If it fits snug, insert the factory bolts and hand tighten. If it is not a snug fit, use a supplied washer between an aluminum bushing and bracket and hand tighten.
8. Lower vehicle
9. Using masking tape, secure a plump bob (or string with a nut tied to the end) to the rear fender on both sides, allowing it to hang
10. Measure the distance from the string to the wheel on each side
11. Turn the panhard bar clockwise or counter-clockwise until both measurements are within 1/8" of each other
12. Apply blue Loctite and tighten jam nuts. If you can get a wrench in there, it is okay to drop one side at a time
13. Tighten the factory bolts to 129 lb-ft.
14. Double check everything and enjoy improved performance!
