How to Install BMR On-Car Adjustable Rear Lower Control Arms - Poly Bushings & Rod Ends - Hammertone on your Mustang

1. Lift vehicle and support with jack stands under the  frame rails.  ​

2. For ease of access, remove both rear wheels/tires.  

3. As shown in IMAGE 1, some exhausts may block  accessibility to the lower control arm bolts in the  frame rail. If this is the case, remove the exhaust  before proceeding.  

4. Using a 13mm wrench or socket, remove the 4  bolts on the sway bar. Remove the sway bar  and set it aside. (IMAGE 2 and 3)  

5. Support the rear end with the jack, then  remove the lower shock bolts using a 19mm or  21mm wrench (most were 21mm but it has  been reported that some years used 19mm  nuts).  

6. Once the shocks are disconnected, carefully lower the  rear end until the springs can be removed. (IMAGE 4)  

7. With the springs and sway bar removed, un-bolt the  lower control arms one side at a time using an 18mm  wrench and 21mm socket.  

8. Using the stock control arm as a guide, adjust the  BMR control arms to the stock length as shown in  IMAGE 5 below.  

9. Install the control arms using the factory hardware.  Tighten the mounting bolts to 131 ft/lbs.  

10. Tighten the jam nuts and adjuster on the BMR control  arms using a 1-1/8”, 1-1/4”, and 1-1/2” wrench.  

11. Re-install exhaust, if necessary.  

12. Re-install wheels/tires then lower vehicle.
