Checking Exhaust SystemABS005Z5
Check exhaust pipes, muffler and mounting for improper attachment,
leaks, cracks, damage or deterioration.

If anything is found, repair or replace damaged parts.
Removal and InstallationABS005Z6
CAUTION:

Be sure to use genuine exhaust system parts or equivalents which are specially designed for heat
resistance, corrosion resistance, and shape.

Perform the operation with the exhaust system fully cooled down because the system will be hot
just after engine stops.

Be careful not to cut your hand on the heat insulator edge.

Tighten main muffler mounting bracket bolts in numerical order
as shown in the figure.
CAUTION:

Always replace exhaust tube gaskets with new ones when reassembling.

If heat insulator is badly deformed, repair or replace it. If deposits such as mud pile up on the heat
insulator, remove them.

When installing heat insulator avoid large gaps or interference between heat insulator and each
exhaust pipe.

Remove deposits from the sealing surface of each connection. Connect them securely to avoid
gases leakage.

Temporarily tighten mounting nuts on the exhaust manifold side and mounting bolts on the vehi-
cle side. Check each part for unusual interference, and then tighten them to the specified torque.

When installing each mounting rubber, avoid twisting or unusual extension in up/down and right/
left directions.
INSPECTION AFTER INSTALLATION

Make sure clearance between tail tube and bumper is even.

With engine running, check exhaust tube joints for gas leakage and unusual noises.

Check to ensure that mounting brackets and mounting rubbers are installed properly and free from undue
stress. Improper installation could result in excessive noise and vibration.

CautionADS000OH
Observe the following precautions when disassembling and servicing drive shaft.

Bearing in wheel joint does not disassemble because it is non-overhaul parts.

Perform work in a location which is as dust-free as possible.

Before disassembling and servicing, clean the outside of parts.

Prevention of the entry of foreign objects must be taken into account during disassembly of the service
location.

Disassembled parts must be carefully reassembled in the correct order. If work is interrupted, a clean
cover must be placed over parts.

Paper shop cloths must be used. Fabric shop cloths must not be used because of the danger of lint adher-
ing to parts.

Disassembled parts (except for rubber parts) should be cleaned with kerosene which shall be removed by
blowing with air or wiping with paper shop cloths.
