Drivetrain and Front Suspension Frame Insulator Replacement
Special Tools
For equivalent regional tools, refer to Special Tools .
Removal Procedure
1.Remove the frame from the vehicle. Refer to Drivetrain and Front Suspension Frame Replacement Drivetrain and Front Suspension Frame Replacement .
2.Remove the upper frame insulator (1)
3.For the removal of a front frame insulator, assemble the
CH-47672-A press as shown.
4.Use the
CH-47672-A press to remove the front frame insulator from the frame.
Note:For the removal of a rear frame insulator, tool cannot be used. Cut the insulator rubber along the interior surface (3) of the plastic outer can with a jigsaw to ease removal of the core.
5.To remove a rear insulator, cut out frame insulator core (1) from frame insulator (2).
6.Remove the rear frame insulator core (1) from the outer frame insulator (2).
7.Remove the rear frame insulator from the drivetrain and front suspension frame using a chisel or equivalent.
Installation Procedure
1.Clean the frame insulator opening.
2.Apply thin coat of rubber lubricant GM P/N 1051717 (Canadian P/N 5728223), or equivalent to the inside of the frame insulator opening and to the insulator.
3.Install the
CH-47672-A clamp to the bushing. Align the clamp screws with the split portion of the bushing. Position the edge of the clamp where the bushing chamfer blends with the straight section of the bushing. Alternately tighten the clamp screws until the split edges of the bushing are parallel and almost touching.
Note:The frame insulator splits must be aligned in a forward and rearward position relative to the vehicle.
4.Install the frame insulator to the front frame opening with the insulator splits aligned in a forward and rearward direction relative to the vehicle.
5.Assemble the
CH-47672-A clamp and the frame insulator as shown to the frame.
6.Use the
CH-47672-A press to begin installing the frame insulator into the frame. STOP and remove the
CH-47672-A clamp (1) before the clamp becomes trapped between the
CH-47672-A press and frame.
7.Use the
CH-47672-A press to finish installing the frame insulator into the frame.
Note:Inspect and confirm that there is NO visible gap between the insulator and the frame.
8.Remove the
CH-47672-A remover/installer from the insulator and frame. Inspect and confirm that the insulator (2) is in direct contact with the frame (1).
9.Install the upper frame insulator (1).
10.Install the frame to the vehicle. Refer to Drivetrain and Front Suspension Frame Replacement Drivetrain and Front Suspension Frame Replacement .
