Lower Arm Rearward Bushing Inspection

NOTE: Some lower arm rearward bushings may exhibit minor surface cracks or separations that will not adversely affect the performance of the bushing. Surface cracks or separations that are 10 mm (0.393 in) or less in depth will function normally and do not require lower arm replacement.

1. With the vehicle in NEUTRAL, position it on a hoist. Refer to Vehicle Jacking and Lifting. Vehicle Lifting

2. Inspect the rubber portion of the lower arm rearward bushing for cracks or a separation between the rubber and the bushing outer sleeve.
- If a crack or separation is found, insert a paper clip or other suitable measuring device into the crack or separation and measure the depth.

- If the bushing has a crack or separation that is greater than 10 mm (0.393 in) in depth, install a new lower arm. Refer to Front Suspension &/or Steering Knuckle.
