CautionEDS0005P
Observe the following precautions when disassembling and servicing drive shaft.
lThe wheel joint cannot be disassembled. Do not attempt to disassemble it.
lPerform work in a location which is as dust-free and dirt-free as possible.
lBefore disassembling and servicing, clean the outside of parts.
lThe disassembly and service location must be clean. Care must be taken to prevent parts from becoming
dirty and to prevent the entry of foreign objects.
lDisassembled parts must be carefully reassembled in the correct order. If work is interrupted, a clean
cover must be placed over parts.
lPaper shop cloths must be used. Fabric shop cloths must not be used because of the danger of lint adher-
ing to parts.
lDisassembled parts (except for rubber parts) should be cleaned with kerosene which shall be removed by
blowing with air or wiping with paper shop cloths.
Precautions for Brake SystemEDS0 00 I0
lWhen installing rubber parts, final tightening must be carried out
under unladen condition* with tires on ground.
*: Fuel, radiator coolant and engine oil full. Spare tire, jack,
hand tools and mats in designated positions.
lUse flare nut wrench when removing or installing brake tubes.
lAfter installing removed suspension parts, check wheel align-
ment and adjust if necessary.
lAlways torque brake lines when installing.

lWhen installing rubber bushings, final tightening must be carried out under unladen conditions with tires
on flat, level ground. Oil will shorten the life of rubber bushings. Be sure to wipe off any spilled oil.
l“Unladen condition” means that fuel, coolant and lubricant are full and ready for drive. However, spare tire,
jack, and hand tools should be unloaded.
lAfter installing the removed suspension parts, always check wheel alignment and adjust if necessary.
lReplace the caulking nut with a new one. Install a new nut without wiping the oil off before tightening.

PRECAUTIONS
General Precautions
EAS000FQ
lDo not operate the engine for an extended period of time without
proper exhaust ventilation.
Keep the work area well ventilated and free of any inflammable
materials. Special care should be taken when handling any
inflammable or poisonous materials, such as gasoline, refriger-
ant gas, etc. When working in a pit or other enclosed area, be
sure to properly ventilate the area before working with hazard-
ous materials.
Do not smoke while working on the vehicle.
lBefore jacking up the vehicle, apply wheel chocks or other tire
blocks to the wheels to prevent the vehicle from moving. After
jacking up the vehicle, support the vehicle weight with safety
stands at the points designated for proper lifting before working
on the vehicle.
These operations should be done on a level surface.
lWhen removing a heavy component such as the engine or tran-
saxle/transmission, be careful not to lose your balance and drop
them. Also, do not allow them to strike adjacent parts, especially
the brake tubes and master cylinder.
lBefore starting repairs which do not require battery power:
Turn off ignition switch.
Disconnect the negative battery terminal.
lIf the battery terminals are disconnected, recorded memory of
radio and each control unit is erased.
lTo prevent serious burns:
Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.
lDispose of drained oil or the solvent used for cleaning parts in
an appropriate manner.
lDo not attempt to top off the fuel tank after the fuel pump nozzle
shuts off automatically.
Continued refueling may cause fuel overflow, resulting in fuel
spray and possibly a fire.
lClean all disassembled parts in the designated liquid or solvent
prior to inspection or assembly.
lReplace oil seals, gaskets, packings, O-rings, locking washers, cotter pins, self-locking nuts, etc. with new
ones.
lReplace inner and outer races of tapered roller bearings and needle bearings as a set.
lArrange the disassembled parts in accordance with their assembled locations and sequence.
lDo not touch the terminals of electrical components which use microcomputers (such as ECM).
Static electricity may damage internal electronic components.
lAfter disconnecting vacuum or air hoses, attach a tag to indicate the proper connection.
