Differentials, electronics and airbag module on the Grand Cherokee WJ

Engine / equipment

Jeep Grand Cherokee WJ (4.0, 4.7 V8 and 2.7 CRD)

Period mentioned

1999–2004

Symptoms

Differential noises, electrical faults (especially the remote central locking), marginal brakes and fast tyre wear; an airbag warning or, in rare cases, airbags deploying by themselves.

Possible cause described

CarsGuide reports complaints of differential problems and electrical gremlins, including the remote central locking, and brakes that are only adequate. In addition, Chrysler recalled Grand Cherokees built from 2002 to 2004 because a defect in the airbag control module could deploy the front or curtain airbags without reason.

Check for the garage

Listen to the differentials on the test drive and check their oil; test the remote locking and all the electrics; check brakes and tyres; check the airbag-module recall by VIN.
