Steps
Support the vehicle and lower the exhaust
Raise the vehicle and support it on stands. Unplug the oxygen sensors, remove the heat-shield and exhaust fasteners, and lower the exhaust with assistance while protecting the wiring.
Mark and remove the driveshaft
Mark shaft orientation at the transmission and differential. Remove the flange bolts, secure the shaft so it cannot drop, and unbolt the center support before lowering it out.
Replace the flex coupler
Remove the coupler fasteners and separate the old part from the shaft. Align the replacement using the reference marks, install fasteners by hand, and tighten to the vehicle's specification.
Reinstall the driveshaft
Raise the shaft into place and align both flange marks. Start the flange and center-support bolts by hand, apply thread locker if specified, and tighten them to the correct vehicle specifications.
Reassemble the exhaust
Lift the exhaust into its hangers, install the crossmember and flange hardware, and fit serviceable gaskets. Reconnect both oxygen-sensor plugs and secure all shields.
Check for leaks and vibration
Start the engine and inspect the exhaust joints for leaks. Confirm the driveline clears surrounding parts, then road-test gently and listen for vibration or knocking.
Check your vehicle’s repair manual for exact specifications and fit.
