Lip seals seal the rotating shafts. The lip seals require special treatment. Lip seals are used on the hydraulic pump shaft of the power steering pump. When the lip seals leak complete the following steps:

1. Inspect the sealing surfaces.
2. Thoroughly clean the sealing surfaces.
3. Replace the seal(s).

Replace the shaft if you find pitting. If there is slight corrosion in the lip seal contact zone, clean the surface of the shaft with crocus cloth. Replace the shaft only if you cannot stop the leakage by smoothing the shaft with crocus cloth.

When you remove a part which forms a sealing surface for an O-ring complete the following steps:

1. Remove the original O-ring seal.
2. Replace the original O-ring seal with a new O-ring seal.

Lubricate all of the new O-ring seals with power steering fluid in order to ease the installation.
