Installation Guidelines
Installation of a driveshaft assembly requires specialized tools and knowledge. It is recommended that this procedure be performed by a qualified automotive technician.
- Safety First: Ensure the vehicle is securely lifted and supported on jack stands. Disconnect the battery.
- Remove Old Driveshaft: Carefully unbolt the existing driveshaft from the differential flange and transmission/transfer case. Note the orientation for proper installation of the new unit.
- Inspect Components: Before installing the new driveshaft, inspect surrounding components such as universal joints, carrier bearings, and mounting surfaces for wear or damage.
- Install New Driveshaft: Align the new Dorman 936-014 driveshaft with the differential flange and transmission/transfer case. Ensure proper indexing if applicable. Bolt securely, adhering to manufacturer torque specifications.
- Check Clearances: Verify that the driveshaft has adequate clearance from other vehicle components throughout its range of motion.
- Final Checks: Lower the vehicle, reconnect the battery, and perform a test drive to ensure smooth operation and absence of vibrations or unusual noises.

Maintenance
The Dorman 936-014 Driveshaft Assembly features serviceable universal joints, which allows for easier and more cost-effective maintenance compared to original equipment designs with permanently staked U-joints.
- Regular Inspection: Periodically inspect the driveshaft for signs of wear, damage, or loose fasteners. Check universal joints for play and carrier bearing for excessive movement or noise.
- U-Joint Service: If equipped with grease fittings, lubricate the universal joints according to vehicle manufacturer recommendations or during routine service intervals. Replace U-joints as needed.
- Cleaning: Keep the driveshaft free from excessive dirt, grime, and debris, which can contribute to premature wear.

Troubleshooting
If you experience issues after driveshaft installation, consider the following common troubleshooting steps:
- Vibration: Driveshaft vibration can indicate improper balance, incorrect installation angle, or worn universal joints/carrier bearing. Re-check installation, balance, and component condition.
- Clunking/Clicking Noises: These noises often point to loose fasteners, worn universal joints, or excessive play in the spline. Inspect all connections and components.
- Whining/Humming: While less common for driveshafts, this could indicate a worn carrier bearing or issues with the differential or transmission.
- Fluid Leaks: Check for leaks around the transmission/transfer case output shaft seal and differential input seal. These are not typically related to the driveshaft itself but can be disturbed during replacement.
If troubleshooting does not resolve the issue, consult a qualified automotive technician.
