46–06 Rack and Pinion
Steering Gear Inspection
WARNING
All steering system components are critical for
safe operation of the vehicle. Failure to maintain
the steering system as specified may result in
loss of steering control, which could lead to per-
sonal injury and property damage.
Inspect the rack and pinion steering system as de-
scribed below, and repair or replace any components
that are worn or damaged.
Figure 4
shows the com-
ponents of the rack and pinion steering system.
1.
Park the vehicle on a level surface, shut down
the engine, and set the parking brake. Chock the
tires.
2.
Check the steering I-shaft U-joints for evidence
of looseness or binding. If any is found, replace
the I-shaft.
3.
Check the steering I-shaft slip joint for evidence
of lateral movement, looseness, or binding. If any
is found, replace the I-shaft.
4.
Jack up one axle end at a time, and move the
tire in and out by hand to check the tie rod ends
for free play. No free play is allowed. If the outer
tie rod ends are damaged or worn, replace them.
See
Group 46
of the
Cascadia Workshop
Manual
for replacement instructions.
5.
Check the steering gear mounting bolts for secu-
rity.
6.
Check that the outer tie rod castle nuts are tight,
and the cotter pins are properly installed.
IMPORTANT: Do not remove the bellows unless
they are damaged and require replacement, or
there is evidence of a loose inner tie rod or
there is hydraulic fluid leak.
7.
Use a clean rag to remove all dirt and debris
from the bellows. Check the bellows for holes or
tears. If any are found, replace the bellows.
8.
Check for evidence of hydraulic fluid leakage
from the bellows. If hydraulic fluid is found to be
leaking from within the bellows, replace the
steering gear.
9.
Check the input shaft for any leakage around the
input shaft seal cover. If there is evidence of
leakage from inside the cover, remove it and re-
place the input shaft seal. See
Group 46
of the
Cascadia Workshop Manual
for instructions.
Check the steering system pressure and return
lines and fittings for leaks and damaged lines or
hoses. Repair or replace lines, hoses, and fit-
tings as necessary.
