DISASSEMBLY
1. Remove cylinder tubes from gear housing assembly.
2. Remove rear cover cap from pinion assembly.
3. Using a rear cover wrench [SST: KV489Q0030] (A) to remove
rear cover from pinion assembly.
4. Remove O-ring using a flat-bladed screw driver, and pull out
rear cover.
5. Measure adjusting screw height “H”, and loosen adjusting
screw.
CAUTION:

Do not loosen adjusting screw 2 turns or more.

Replace steering gear assembly if adjusting screw is
loosened 2 turns or more and it is removed.
6. Remove pinion assembly from gear housing assembly.
7. Loosen outer socket lock nut, and remove outer socket.
8. Remove boot clamp, and then remove boot from inner socket.
CAUTION:
Do not damage inner socket and gear housing assembly
when removing boot. Inner socket and gear housing assembly must be replaced if inner socket
and gear housing assembly are damaged because it may cause foreign material interfusion.
