Inspection (RAV4)

With rack mounted horizontally on "V" blocks, use dial indicator to measure rack runout. Runout should not exceed .012" (.3 mm). Check rack and teeth for wear and damage. Replace rack if necessary.
Using cylinder gauge, measure inside diameter of rack housing bushing. Maximum diameter should not exceed 1.11" (28.2 mm). Using micrometer, measure outside diameter or control valve. Minimum diameter should not exceed 1.09" (27.69 mm). Replace components if necessary.
If necessary, use puller to extract bushing from rack housing. Using screwdriver, carefully tap oil seal upward out of rack housing. Coat NEW seal lip with power steering fluid. Using seal installer, carefully tap NEW seal into place from upper side of rack housing. Make sure oil seal is facing same direction as removed.
Coat NEW bushing with molybdenum disulfide lithium-base grease. Using press, install bushing against oil seal in rack housing.
If necessary, use screwdriver to remove Teflon ring and "O" ring from steering rack. Coat NEW "O" ring with power steering fluid. Install "O" ring. Carefully expand NEW Teflon ring by hand, only enough to accommodate installation. Coat Teflon ring with power steering fluid. Press ring into rack groove. Use ring installer to fully seat ring.
If necessary, use screwdriver to remove 4 Teflon rings from control valve assembly. Coat NEW rings with power steering fluid. Slightly expand rings by hand, and install in each groove. Use installer tool to slide over rings and fully seat them.
If necessary, use screw extractor to remove 2 union seats from rack housing. See Figure. Use drift and hammer to tap in 2 NEW union seats.
Check cylinder end stopper bushing for wear or damage. If necessary, replace cylinder end stopper (bushing is not replaceable separately). Coat inside of bushing with molybdenum disulfide lithium-base grease.
