24. With your finger, check the inner wall of the valve housing where the seal ring slides. If there is a step

in the wall, the housing is worn. Replace it.

NOTE:

There may be sliding marks from the seal ring on the wall of the valve
housing. Replace the valve housing only if the wall is stepped.

Reassembly

31. Apply power steering fluid to the surface of the ball joint boot clip guide. Slip two new seal rings (A)

over the ball joint boot clip guide from the smaller diameter end, and expand them. Install only two
rings at a time from each end of the pinion shaft sleeve (B).

Note these items when installing the seal ring:



Do not over-expand the seal ring. Install the resin seal rings with care so as not to damage them.
After installation, make sure you contract the seal rings using the sleeve seal ring sizing tool.



There are two types of sleeve seal rings: black and brown. Do not mix the different types of
rings as they are not compatible.

32. Align the ball joint boot clip guide with each groove in the sleeve, and slide a sleeve seal ring into

each groove. After installation, compress the seal rings with your fingers temporarily.

33. Apply power steering fluid to the seal rings on the sleeve, and to the entire inside surface of the sleeve

seal ring sizing tool, then slowly insert the sleeve into the sleeve seal ring sizing tool.

34. Move the sleeve back and forth several times to make the seal rings snugly fit in the sleeve. Make sure

the seal rings are not twisted.

35. Apply power steering fluid to the surface of the pinion shaft (A). Slide the sleeve (B) onto the pinion

shaft by aligning the locating pin (C) on the inside of the sleeve with the cutout (D) in the shaft. Then
install the new snap ring (E) securely in the pinion shaft groove. Be careful not to damage the valve
seal ring when inserting the sleeve.
