It is important to inspect and maintain the driveshaft assembly to ensure its proper function and prevent issues like noise or vibration while driving. The driveshaft should be kept clean and free from undercoating, mud, or debris. Additionally, it's essential to check that the small weights used to balance the driveshaft are securely attached. When removing and reinstalling the driveshaft, it must be reinstalled in the same relative position to preserve its balance.

Driveshafts have a "slip yoke" at the front end that inserts into the extension housing of the transmission or transfer case. On two-piece rear driveshafts, a center bearing supports the driveline. The rear end of all rear driveshafts connects to the rear axle's differential pinion flange using a flange yoke with four bolts. Front driveshafts on 4WD models may have a slip yoke at either the front or rear end, depending on the vehicle type.

Mark the relationship between the driveshaft and the differential pinion flange. Remove the rear universal joint bolts. If applicable, remove the center bearing support bracket bolts on two-piece driveshafts. Lower the rear driveshaft. Slide out the slip yoke from the transmission or transfer case. Remove the driveshaft assembly while protecting the extension housing with a plastic bag. While the driveshaft is removed, inspect and replace the extension housing seal and differential pinion seal if necessary.

When dealing with a one-piece driveshaft, you should slide the front end of the driveshaft out of the transmission extension housing.
