REPAIR PROCEDURE:

NOTE: The majority of knocks can be heard at approximately 25 mph (40 kph) on rough roads or
over single-wheel inputs / shock. It is important to identify a test route that highlights the customer
concern of suspension knock and re-test the vehicle over the same test route when identified in the
following procedure. The test route should include roads that have a broken road surface or drain covers
that allow single-wheel inputs, etc. The vehicle speed that highlights the issue should be noted during the
initial appraisal of the customer concern and then replicated on subsequent test drives.

1. Raise vehicle on a suitable ramp (TOPIx Workshop Manual section 100-02).
2. Identify if body mount dampers are installed to the
vehicle.
Reposition the road wheel to gain access to

splash shield top grommet ('1').
Remove splash shield top grommet.

3.

NOTE: Front left-hand body mount
damper shown with splash shield removed
for clarity; right-hand body mount damper
similar.

If installed, remove and discard the body mount
damper.
Install the splash shield top grommet.

4. If no mass absorber is installed, install the mass
absorber.
Clean the underside of the second body mount

carrier (located slightly rearward of the front
wheel) to remove any contamination.
Install a mass absorber to the second body
mount carrier using the two bolts per mass
absorber provided in the mass absorber kit.
Keep the lower face of the mass absorber
parallel with the ground.
Tighten bolts to 115 Nm (85 lbf ft).

5. If required, carry out steps 2-4 to the opposite side of the vehicle.
6. Remove the front stabilizer bar bushing (TOPIx
Workshop Manual section 204-06).
Inspect the Dynamic Response™ bush clamps.
If the old-design Dynamic Response™ bush

clamps are installed (with internal ridge),
discard the Dynamic Response™ bush clamps
and install the new-design Dynamic Response™
bush clamps (no internal ridge) in step 8.
If the new-design Dynamic Response™ bush
clamps are installed (no internal ridge), re-use
the Dynamic Response™ bush clamps in step
8.

7.

CAUTION: Make sure that the stabilizer
bar is cleaned back to the paint but do not
remove the paint.

CAUTION: The paint on the stabilizer bar
may have worn away; this is an acceptable
condition. Do not install a new stabilizer bar
for this issue.
Inspect the condition of the front stabilizer bar.
Remove any dirt or debris from the section of

the stabilizer bar that is clamped in the bush.
Paint, if present, does not need to be removed.
If required, use a suitable strip of 320 grade
abrasive paper/cloth to remove any built-up
deposits. Use a suitable brake cleaner to
remove any dirt or grease residue.

8.

CAUTION: Make sure the faces of the
bush clamp and the upper and lower mating
faces of the chassis are clean, smooth and
free from debris. Use a suitable brake cleaner
to remove any dirt or debris from the mating
faces.

CAUTION: Make sure that the new design
Dynamic Response™ bush clamps are
installed (see step 6).
Install the front stabilizer bar bushing and, if
necessary, new-design Dynamic Response™ bush
clamps (TOPIx Workshop Manual section 204-06).

9. Road test the vehicle. If the 'knock' is still evident, carry out Technical Bulletin LTB00204.
