5. TESTING FOR NOISE:
Checking for wheel side (CV) joint noise:
(This noise will appear to emanate closer to the
wheel, rather than the engine).
1. Shift to the 2nd gear and maintain a steady
speed between 20 and 30 kmph (12 and 18
mph).
2. Drive the car to form a figure of “8” as shown
in the (Fig. 4) Identify an audible and
persistent “Cluck” – like noise during either
an extreme left or extreme right turn.

3. The “Clucking” noise on a particular turn can
be confirmed by repeating the turn.
Checking for engine side joint noise:
(This noise will appear closer to the engine, than
the wheel).
1. Shift to the 4th gear and maintain a steady
speed between 40 and 60 kmph (24 and 36
mph).
2. Lower the car speed by gently applying the
brakes while ensuring that the tyres do not
screech and the car does not dive forward
sharply.
3. Identify an audible “Dug” sounding noise as
the car decelerates.
As the car slows down, it can be observed
that the sound would become louder and
occur after longer intervals.
