Vibration Conditions

NOTE:
- CV joints should not be replaced unless disassembly and inspection reveals unusual wear.
- Halfshafts are not balanced and do not normally contribute to rotational vibration disturbances.

Clicking, popping or grinding noises may be caused by the following:
- cut or damaged rear axle shaft outer boots or rear axle shaft inner boots, resulting in inadequate or contaminated lube in outboard or inboard cv joint stub shaft pilot bearing housings.
- loose rear axle cv joint boot clamps
- another component contacting the halfshaft assembly
- worn, damaged or improperly installed wheel bearing, suspension or brake component

Vibration at highway speeds may be caused by the following:
- out-of-balance front or rear wheels
- out-of-round tires

Shudder or vibration during acceleration may be caused by the following:
- excessively worn or damaged outboard or inboard cv joint stub shaft pilot bearing housing
- excessively high cv joint operating angles caused by improper ride height. Check the ride height, verify the proper spring rate

Halfshaft or cv joint pullout may be caused by the following:
- Rear axle carrier assembly mispositioned. Check the suspension components for proper location, damage or wear.
- Rear sub-frame damaged.
- Rear suspension components worn or damaged. Check for worn bushings or bent components (rear stabilizer bar link and bushing, rear suspension arm and bushing).
