The drivetrain of any vehicle is not a singular component. Rather, it is a collection of mechanisms - such as the axles, CV joints, differential, driveshaft, and transmission - that collaborate with the engine to move the wheels. There are three types of drivetrains including 2WD, 4WD, and AWD. This article covers some of the most common elements that may need to be replaced.
First are the drive axle boots. These accordion-style covers are flexible and conical in shape. the hold lubricant and are designed to protect the CV joints that are mounted to the drive axle shaft.
Next is the drive belt tensioner. This is a self-adjusting device that is responsible for maintaining tension along the drive belt - which is positioned on a crankshaft pulley. It is the belt’s job to transfer rotation from the engine to other mechanisms like the power steering pump, the alternator, and more.
Then, the drive shaft is a hard metal tube that connects the motor to the differential on RWD or 4WD models. It can universal joints on both ends. finally, the drive train mounts are energy-absorbing pieces that attached different parts - such as the transfer case or transmission - to the chassis.
