Assembly NOTE: Proper seal installation tools and procedures must be used to prevent damage to seals during assembly. Lubricate the new pressure seal and dust seal with Ford Multi-Purpose Grease D0AZ-19584-AA (ESR-M1C159-A) or equivalent. Apply Ford Multi-Purpose Grease D0AZ-19584-AA (ESR-M1C159-A) or equivalent to the sector shaft seal bore. Place the dust seal on Sector Shaft Replacement Tool T77L-3576-A so the raised lip of the seal is toward the tool. NOTE: Failure to use proper seal installation tools and procedures may damage the seals and cause a fluid leak. Place the pressure seal on the tool with lip away from the tool. The flat back side of the pressure seal should be against the flat side of the dust seal. Insert the seal driver tool into the sector shaft bore and drive the tool until the seals clear the snap ring groove. Do not bottom seals against bearing. The seal will not function properly when bottomed against the bearing. Install snap ring in the groove in the steering gear housing . Apply a generous amount of Ford Multi-Purpose Grease D0AZ-19584-AA (ESR-M1C159-A) or equivalent, to the areas between the two seal lips.
