Routinely replace lower-cost items such as springs, seals,
bushings, and heavily-worn but unbroken parts since the
damage caused, should these components fail, is far in excess
of their cost.

1. Remove air chamber bracket, see Removal / Disassembly - Air
Chamber Bracket Removal.
2. Drive out old bushings and grease seals with a suitable driver.
3. Clean and inspect air chamber bracket, see Inspection - Air
