How to Install GMS Differential Mount on your Mustang

REA R DIFFERENTIAL BUSHINGS REMOVAUINSTALLATION 
ATTENTION:

We recommend acquiring a Ford factory workshop manual for all warnings and procedures to safely remove and install the rear sub frame, drive shaft, differential, half shafts and rear knuckles. Or go online to www.helminc.com for an Online Service Information Subscription. Ford requires replacement of all hardware with any self-locking feature; refer to the factory workshop manual for examples of self-Jocking nuts and bolts. This instruction set is intended as a guideline for the safe installation of Energy Suspension's polyurethane differential bushings, once you have removed the factory rear sub frame from your vehicle. Check that the parts you received in this kit match the parts listed on page 2.
(Fig. 1) A portable 10 ton hydraulic pull back ram was used to remove the factory rubber bushings and should be available from any tool and equipment rental company in your area.
(Fig. 2) Remove the 4 bolts that mount the differential to the factory rubber bushirigs and set aside.
(Fig. 3) All 4 factory rubber bushings have the same size outside diameter and will use the same setup to remove)each position.
(Fig. 4 & 5) The outer metal shell of the factory rubber bushing must be pressed out.
(Fig. 6) After all 4 factory rubber bushings have been removed, remove all sharp edges on sub frame that will contact the polyurethane bushings. Install the new polyurethane bushings as shown in the parts diagram above. Position the differential in the sub frame and install the supplied bolts. Torque the rear bolts to 129 ft·lb and torque the front nut and bolts to 129 ft·lb. Reinstall the sub frame according to the factory workshop manual. After completing the installation, double check that all hardware has been properly torqued to factory specs. You should periodically inspect all hardware and components and replace any damaged components as necessary to maintain the reliability of your vehicle. *Note: Installing firmer polyurethane sub frame and/or differential bushings will increase NVH and driveline noise.
