you literally can get no where without a functioning drivetrain
The driveline, also referred to as the drivetrain, consists of all the components involved in transferring the power between the transmission and wheels. With such an important role, you can only get so far with a damaged driveline. As with other automotive services, it's always best to refer to your owner's manual to see when your manufacturer recommends driveline service. Typically, we suggest that you get an inspection and replace the differential fluid every 30,000-60,000 miles. Over time, some driveline components may also get worn. In that case, you will need to replace its parts. Some of the signs that indicate you’re due for repairs:
Shakiness or vibrations from under the vehicle,
Difficulty making turns,
Unusual noises, like clunking sounds, when driving at high speeds, and
Vehicle shudders when accelerating.
