Component

Power train: transfer case (4-wheel drive)

Summary

"situation: a rubbing/scraping/drone-type noise and/or a vibration may appear to be evident from the front left-hand corner of the vehicle. The noise may also be described as similar to a brake rubbing or wheel bearing noise and can be variable from vehicle to vehicle. The issue can occur at different speeds/gears and in steady state driving conditions up to 50/60mph (80/100km/h). The noise in most cases is more prominent in second gear coast down, particularly around 12mph (20km/h). To confirm the transfer case is the root cause, the noise can listened to using a ‘chassis ear’ fixed to front differential right-hand mount. Cause: this may be caused by a chordal vibration of the transfer case chain on coast/overrun."
