Which symptom indicates a failing centre bearing?

  • A.A whine under acceleration
  • B.A knock when reversing, which is caused by the backlash within the splines of the sliding joint on the shaft
  • C.Vibration and a rumble at particular road speeds
  • D.A clicking noise on full lock, which is produced by the wear of the joint at the outer end of the shaft assembly

Answer: C

A worn bearing or a perished rubber carrier allows the shaft to move and produces vibration that peaks at the speeds corresponding to the shaft resonances. Inspection with the vehicle raised usually reveals excessive play. Replacement is straightforward. Working the distinction through on a single concrete case fixes it more firmly than any rule of thumb. Naming the cost of a choice alongside its benefit is what turns a fact into a design decision.
