Drivetrain: Diagnostic Test Drive
Once the vehicle is moving, you might hear a whine coming from the center of the vehicle. The noise will change as speed increases and might change as power is applied.

Chances are the driveshaft is disengaged. This can happen if the vehicle had earlier transmission or body shop work and the
Driveshaft Service
Driveshafts on most rear-wheel drive and four-wheel drive (4WD) vehicles are very durable. Most late-model driveshafts are not serviceable and do not have any lubrication points. But, this does not mean that they can’t wear, or even fail. Driveshaft problems can be spotted from the moment you put the vehicle in gear to pull it
