1

A vehicle has a burnt friction disc in the clutch. Technician A says it could be caused by too much clutch pedal free play. Technician B says binding linkage may have caused it. Who is right?

  1. A only
  2. B onlyAnswer
  3. Both A and B
  4. Neither A nor B

Why that is right

Technician A is wrong because too little clutch pedal free play would affect disengagement, not engagement. Technician B is correct because binding linkage can cause slippage and, thus, a burnt surface may have caused it.

Why the other options are wrong

  • A only — A only is wrong because Technician A is incorrect. Too MUCH free play reduces disengagement travel (a release problem), while too LITTLE free play holds the clutch partially released and causes slipping and burning. A has the cause-and-effect reversed.
  • Both A and B — Both A and B cannot be correct because Technician A's statement about too much free play causing a burnt disc is wrong. Only Technician B's binding-linkage cause is valid.
  • Neither A nor B — Neither A nor B is wrong because Technician B is correct. Binding linkage prevents the pressure plate from fully clamping, allowing slippage and a burnt friction surface, so at least one technician is right.

A technician is removing a semi-floating axle shaft that is held in by C-locks. What is the first step in the procedure after the vehicle is raised and the wheels are removed?

  1. Use a slide hammer to pull the axle shaft straight out of the housing.
  2. Unbolt the bearing retainer plate at the end of the axle tube.
  3. Remove the differential cover and drain the fluid.Answer
  4. Unbolt the companion flange from the driveshaft.

Why that is right

On a C-lock (C-clip) axle the retaining clips sit inside the differential carrier on the button end of each axle shaft, so the differential cover must be removed and the gear oil drained before the shafts can be freed.

Why the other options are wrong

  • Use a slide hammer to pull the axle shaft straight out of the housing. — A slide hammer is used to pull a bearing-retainer (bolt-in) type axle; a C-lock axle is retained internally and cannot simply be yanked out, and this is never the first step.
  • Unbolt the bearing retainer plate at the end of the axle tube. — This is the removal method for a retainer-plate/bolt-in axle. A C-lock axle has no bearing retainer plate to unbolt.
  • Unbolt the companion flange from the driveshaft. — The driveshaft and companion flange do not need to be disturbed to remove a rear axle shaft; that is unrelated to freeing the C-locks.
