Noisy front bear­ing

Car Mechanics (UK) - - CM Insider -

Some­times the ad­vice gleaned from a friend down the pub is not al­ways the best in­for­ma­tion on which to base a di­ag­no­sis.

The owner of this 2008 Nis­san Qashqai in­sisted the 02 sen­sor was faulty due to a ran­dom com­ment made by a mate. Driv­ing us around the block to show us the fault, she pointed out the hum­ming noise com­ing from the off­side front wheel bear­ing.

This made the re­pair much eas­ier: we sim­ply needed to re­place the bear­ing, not the sen­sor, de­spite what her friend had said. Fit­ting a new bear­ing on the Qashqai is par­tic­u­larly easy as the bear­ing and hub assem­bly are in a sin­gle unit that is sim­ply bolted in place. The one thing to watch is to en­sure that the ABS sen­sor is de­tached be­fore try­ing to re­move the hub from the car­rier.

Re­mem­ber to dis­con­nect the ABS sen­sor be­fore re­mov­ing the hub.
