Preparing to install the mounts

  • 6 GM bolts part # 11517635 (Gm Parts Direct) You may be able to source them elsewhere. The GM bolt is metric with larger bolt head 18mm and slightly thicker on the shaft near bold head. Bolts are 4 inches long from underside of head to tip.  4.5 inches long overall and fit Dorman mounts perfectly.

  • 1 or 2 nuts that fit new center bolts (NAPA part number 81477). 1 nut is needed for use in compressing and seating the mounts in the frame. The extra nut is a spare.
  • One Washer used for compressing and seating bushings ( used one of the good factory top washers from the factory mounts, you will likely get a good one from one of the front mounts. They drop into the top of the Dorman washer and are perfect for the seating/compressing of the bushings explained later in this document.

Tools Needed for Removal and Install

  • 1/4, 3/8, and 1/2 inch ratchets
  • 10mm, 13mm, 15mm, 18mm sockets
  • PB Blaster
  • Impact wrench (Air and or Electric)
  • 4 Jack Stands
  • Floor Jack
  • 1/2 drive Torque Wrench.
  • 19mm wrench to hold nut for mount seating/compression
  • Cutting, Grinding Tools ( Only needed if you break off center bolt during removal and to remove any broken off 10 mm studs from factory mounts )

Support the car for cradle mount removal/install:

I jacked and supported the car on the right side, completed the install on that side then jacked and did the left side. You could probably jack both sides and support car/cradle and should work fine. Using floor jack, jack up the car enough to remove tires, remove tires,

Place one jack stand between rear mounts on engine cradle and one on each side of the cradle in the front. The car should now be supported by 4 jack stands under the engine cradle.

Make certain the car is supported safely with the jack stands before continuing with this procedure.
