Steps
Lower the exhaust and remove the shaft
Raise and support the vehicle, unplug the oxygen sensors, and move the exhaust out of the way. Mark the shaft and flange positions, support the shaft, then unbolt and remove it.
Separate the shaft sections
Mark the spline relationship before splitting the shaft. Cut the old boot clamp, remove the boot and dust shield, then remove the snap ring and bearing components in order.
Pull off the worn bearing
Use a bearing separator and puller positioned behind the bearing race. Apply controlled force to remove the bearing without gouging the shaft or damaging its sealing surfaces.
Install the new bearing and boot
Grease the bearing journal as specified and press the new bearing squarely into place. Refit the snap ring, dust shield, boot, and clamp, then align the original spline marks.
Reinstall the shaft
Lift the driveshaft into position and align the flange marks. Start the fasteners by hand, apply thread locker where specified, and tighten the flange and support bolts to vehicle specifications.
Restore the exhaust and verify
Reinstall the exhaust and reconnect the oxygen sensors. Check for leaks and abnormal shaft movement, then perform a cautious road test while listening for vibration.
Check your vehicle’s repair manual for exact specifications and fit.
