The technician should have a thorough knowledge of driveline system operation and accepted general driveline guidelines to detect any problems.
A gear driven unit will produce a certain amount of noise. Some noise is acceptable and audible at certain speeds or under various driving conditions.
Certain conditions, such as road conditions and weather, will amplify normal vehicle noise.
Certain rear axle and driveline concern symptoms are also common to the engine, transmission, rear wheel bearings and tire. For this reason, be sure
the cause of the concern is in the axle before repairing or installing any axle components.
This is a guide to diagnose a driveline concern:
^
Verify and document the customer concern.
^
Carry out a preliminary investigation.
^
Road test the vehicle.
^
Find the cause of the problem.
^
Inspect the components.
1. Verify and document the customer concern.
1
When was it first noticed?
2
Did it appear suddenly or gradually?
3
Did anything unusual occur that would coincide with it or precede it?
4
Has the driveline system been repaired before or new components installed?
^
Check the vehicle service record. Note any repairs other than driveline, such as brakes or suspension.
5
Are there any special conditions that will affect the concern or will alter the concern? For example,
^
road speed.
^
type of road.
