Sub-frame bushings

Good evening,

There are three sets of bushings on each side.

You can get them at a dealer parts department.

You need a lift with a jack will allow the frame to drop enough to access the bushings. This is not an easy job at all.

1. Remove the front air deflector. Refer to Front Air Deflector Replacement (See: Air Dam > Removal and Replacement > Front Air Deflector Replacement) in Body Front End.
2. Raise the vehicle using a frame contact hoist. Refer to Lifting and Jacking the Vehicle.
3. Support the frame near the insulator using jack stands.
4. Remove the following components from the insulator (4):

* The bolt (6)
* The retainer (5)
Important: If working on position #2 or #3, other insulator mounting bolts must be removed to remove insulator.

5. Loosen other insulator bolts.
6. Remove the lower insulator (4).
7. Raise the body slightly.
8. Remove the following components:

* The upper insulator (2)
* The spacer (1)

Hi and thanks for using 2CarPros.

With this type of job, I would recommend getting the parts from a dealer. You don't want to take a chance of having to replace them again in a year. IT isn't a simple job.
