Clean, high quality brake fluid is essential to
the safe and proper operation of the brake
system. You should always buy the highest
quality brake fluid that is available. If the
brake fluid becomes contaminated, drain and
flush the system, then refill the master cylin-
der with new fluid. Never reuse any brake
fluid. Any brake fluid that is removed from
the system should be discarded. Also, do not
allow any brake fluid to come in contact with
a painted surface; it will damage the paint. Measure the brake pedal height from the floor of
the vehicle to the upper surface of the brake pedal.
The distance should be 6.9-7.1 in (176181mm). If
the brake pedal height is incorrect, adjust as follows:
1. Detach the stop lamp switch connector.
2. Loosen the locknut on the base of the stop
light switch and move the switch to a position where
it does not contact the brake pedal.
3. Loosen the operating rod locknut. Adjust the
height of the brake pedal by turning the operating rod
using pliers. Once the desired pedal height is ob-
tained, tighten the locknut on the operating rod.
4. Screw the stop light switch until the it contacts
the brake pedal stopper. Turn switch in until the
brake pedal just starts to move. At this point, return
(loosen) the stoplight switch $-1 turn and secure in
this position by tightening the locknut. In this posi-
tion, the distance between the lower stop light switch
case and the brake pedal stop should be 0.02-0.04

5. Attach the electrical connector to the stop light
switch.

clutch disc.
c. Clutch pressure plate is weak. Remove engine or transmission and replace the clutch
pressure plate and clutch disc.
d. Clutch pressure plate and/or flywheel incorrectly machined. If the clutch system has
been recently replaced and rebuilt, or refurbished parts have been used, it is possible
that the machined surfaces decreased the clutch clamping force. Replace defective
parts with new replacement parts.
2. Clutch will not disengage, difficult to shift
a. Check the clutch release mechanism. Check for stretched cables, worn linkages or
failed clutch hydraulics and replace defective parts. On hydraulically operated clutch
release mechanisms, check for air in the hydraulic system and bleed as necessary.
b. Check for a broken, cracked or fatigued clutch release arm or release arm pivot. Re-
place defective parts and properly lubricate upon assembly.
c. Check for a damaged clutch hub damper or damper spring. The broken parts tend to
become lodged between the clutch disc and the pressure plate. Disassemble clutch
system and replace failed parts.
d. Check for a seized clutch pilot bearing. Disassemble the clutch assembly and replace
the defective parts.
e. Check for a defective clutch disc. Check for warpage or liningthicknesses larger than
original equipment.
3. Clutch is noisy when the clutch pedal is pressed
a. Check the clutch pedal stop and pedal free-play adjustment for excessive movement
and adjust as necessary.
b. Check for a worn or damaged release bearing. If the noise ceases when the pedal is re-
leased, the release bearing should be replaced.
c. Check the engine crankshaft axial play. If the crankshaft thrust bearings are worn or
damaged, the crankshaft will move when pressing the clutch pedal. The engine must
be disassembled to replace the crankshaft thrust bearings.
4. Clutch pedal extremely difficult to press
a. Check the clutch pedal pivots and linkages for binding. Clean and lubricate linkages.
b. On cable actuated clutch systems, check the cable routing and condition. Replace
kinked, frayed, damaged or corroded cables and check cable routing to avoid sharp
bends. Check the engine ground strap for poor conductivity. If the ground strap is
marginal, the engine could try to ground itself via the clutch cable, causing premature
failure. c. On mechanical linkage clutches, check the linkage for binding or misalignment. Lubri-
cate pivots or linkages and repair as necessary.
d. Check the release bearing guide tube and release fork for a lack of lubrication. Install a
smooth coating of high temperature grease to allow smooth movement of the release
bearing over the guide tube.
5. Clutch pedal remains down when pressed
a, On mechanical linkage or cable actuated clutches, check for a loose or disconnected
link.
b. On hydraulically actuated clutches, check the fluid level and check for a hydraulic leak
at the clutch slave or master cylinder, or hydraulic line. Replace failed parts and bleed
clutch hydraulic system. If no leakage is noted, the clutch master cylinder may have
failed internally. Replace the clutch master cylinder and bleed the clutch hydraulic sys-
tem.
6. clutch chatters when engaging
a. Check the engine flywheel for warpage or surface variations and replace or repair as
necessary.
b. Check for a warped clutch disc or damaged clutch damper hub. Remove the clutch
disc and replace.
c. Check for a loose or damaged clutch pressure plate and replace defective components.
NOTE: The clutch is actuated either by a mechanical linkage, cable or a
clutch hydraulic system. The mechanical linkage and cable systems may
require the clutch pedal free-play to be adjusted as the clutch disc wears. A
hydraulic clutch system automatically adjusts as the clutch wears and, with
the exception of the clutch pedal height, no adjustment is possible.
1. Differential makes a low pitched rumbling noise
a. Check fluid level type and amount. Replace the fluid with the recommended type and
amount of lubricant.
b. Check the differential bearings for wear or damage. Remove the bearings, inspect the
drive and driven gears for wear or damage, and replace components as necessary.
2. Differential makes a howling noise
a. Check fluid level type and amount. Replace the fluid with the recommended type and
amount of lubricant.
b. Check the differential drive and driven gears for wear or damage, and replace compo-
nents as necessary.
All Wheel and Four Wheel Drive Vehicles
1. Leaks fluid from seals or vent after being driven
a. Fluid level overfilled. Check and adjust transfer case fluid level.
b. Check for a restricted breather or breather tube, clear and check the fluid level and top
off as needed.
c. Check seal condition and replace worn, damaged, or defective seals. Check the fluid
level and top off as necessary.
2. Makes excessive noise while driving
a. Check the fluid for the correct type of lubricant. Drain and refill using the recom-
mended type and amount of lubricant.
b. Check the fluid level. Top off the fluid using the recommended type and amount of lu-
bricant.
c. If the fluid level and type of lubricant meet specifications, check for internal wear or
damage. Remove assembly and disassemble to inspect for worn, damaged, or defec-
tive components.
3. Jumps out of gear
a. Stop vehicle and make sure the unit is fully engaged.
b. Check for worn, loose or an improperly adjusted linkage. Replace and/or adjust link-
age as necessary.
c. Check for internal wear or damage. Remove assembly and disassemble to inspect for
worn, damaged, or defective components.
Rear Wheel, All Wheel and Four Wheel Drive Vehicles
1. Clunking noise from center of Vehicle shifting from forward to reverse
a. Worn universal joint. Remove driveshaft and replace universal joint.
2. Excessive vibration from center of vehicle when accelerating
a. Worn universal joint. Remove driveshaft and replace universal joint.
