BMW X5: Powertrain
Affects BMW X5 · 2004 — about 40 vehicles.
The hazard
On certain vehicles, insufficient tightening torque may have been applied to certain front drivetrain fasteners. Specifically, the affected fasteners are those involving the front differential, the right output shaft housing flange at the engine, and the right-hand engine support. Insufficient torque could lead to a loosening of a fastener. If this happens, at first, noise would be perceptible to the driver. During prolonged driving, sufficient loosening of a fastener could cause damage to a fastener's threading, as well as, to engine and transmission housings. In extreme cases, the right output shaft could become disconnected. Correction: Dealer will inspect and retighten the drivetrain fasteners to their specified values.
