Some customers may comment on what appears to be fluid seepage from around the power steering (PS) gear sector (output) shaft. Typically this seepage appears as a wetting condition around the sector (output) shaft area of the steering gear and, in severe cases, may result in a dripping condition.
Poor sealing capability of the dust cap may result in the grease, utilized for steering gear bearing lubrication, to weep past the dust cap resulting in the wetting condition. This condition is only a cosmetic issue and does not in any way affect the performance of the vehicle steering gear.
Install new seals and cover contained in P/N 88892856, Cover Kit, following the service procedure below.
Notice: Do not hammer on the pitman arm, steering gear sector (output) shaft or puller. Damage to the pitman arm or steering gear may result.
