Rack Assembly





1) Fixing rack housing
Fix rack housing in vice using ST. ST 926200000 STAND

CAUTION:
- When fixing rack housing in vice, be sure to use this special tool. Do not fix rack housing in vice using pad such as aluminum plates, etc.
- When using old rack housing, be sure to clean and remove rust before assembling. Check pinion housing bushing carefully.





2) Fit ST over toothed portion of rack assembly, and check for binding or unsmooth insertion. If any deformation is noted on flats at the end of rack, shape by using file, and wash with cleaning fluid.
3) Apply genuine grease to teeth of thoroughly washed rack assembly, and fit ST over the toothed portion. ST 926390001 COVER & REMOVER

NOTE:
- Be careful not to block air passage with grease. Remove excessive grease.
- After fitting cover, check air passage hole for clogging.
If clogged, open by removing grease from the hole,
- Check rack shaft for damage.
- Apply ATF DEXRON II to this ST and surface of piston ring to prevent seal from being damaged.





4) Insert rack assembly into rack housing from cylinder side, and remove ST after it has passed completely through oil seal.
