- Remove the bolts connecting the crossmember to the body mounts
- Pull down the passenger side of crossmember to clear body mounts and rotate it to the rear until the drivers side mount is free. (It may be helpful to remove the transmission mount for extra working room)

- From the table below, set the proper mounting arrangement of the sleeves for your vehicle by firmly pushing on the end, do not use a hammer
- Place the nylon mounting spacers on the sleeves, position the crossmember into place, and loosely secure with the hardware provided. *Mounting pad on crossmember goes to the FRONT*
*Note: if stud style OEM transmission mount is used, and a flat spacer is required, it must be installed on studs before crossmember is raised into place*
- Per table 2, or table 3 recommendations insert flat spacer(s) between the mount, and crossmember if required. Slightly raise the transmission if more clearance is needed to input spacer(s)
- Loosely install transmission mount bolts
- Lower, and remove jack supporting transmission. FINAL TIGHTEN ALL FASTENERS
