Your vehicle's transmission yoke is designed to be a mounting point for your drive shaft and seal the back of your transmission. It works with the splines to allow free movement of the drive shaft. The yoke is subjected to an enormous amount of wear and tear. When it starts to fail, you will need to replace your entire drive shaft to make sure your vehicle will run properly. Free yourself from the old yoke! It's a project you can do yourself.
Difficulty Level: Moderate
Here's what you'll need:
- Wheel chocks
- 1/2-inch drive ratchet
- 1/2-inch drive socket set
- Hand-held sledgehammer
- Torque wrench
- Replacement drive shaft assembly
- Safety glasses
- Vehicle owner manual
Step 1: Make sure your vehicle is parked on level ground and engine has cooled over a few hours before you begin. Place the wheel chocks in front of the front wheels and behind the rear wheels.
Step 2: The yoke is at the back of the transmission that is connected to the front of your drive shaft. Slide under your vehicle and use your ratchet and a socket to loosen and remove the U-joint cap bolts holding the front drive shaft yoke to the transmission yoke.
Step 3: Your front drive shaft U-joint needs to clear the transmission yoke. To achieve this, pull back on the front drive shaft yoke. Use your hand-held sledgehammer to tap at any components that are stuck.
Step 4: Carefully remove the front part of your drive shaft and set it aside. Use your ratchet and a socket to remove the U-joint strap bolts holding the rear of your drive shaft to the rear-end yoke.
Step 5: Carefully pull the rear of your drive shaft free of the rear-end yoke. If it's stuck, tap it with your sledgehammer. Extract your old drive shaft from under your vehicle.
Step 6: Install your new drive shaft assembly. Secure the U-joint of the front part of the drive shaft to the yoke at the back of your transmission by first placing the U-joint straps onto the yoke, then screwing the strap bolts into it, and finally tightening the strap bolts with your ratchet and socket. Use your torque wrench and a socket to torque the strap bolts down to 25-30 foot-pounds (or as specified by your owner manual).
Step 7: Repeat Step 6 for the rear drive shaft yoke and the rear-end yoke.
Step 8: Remove the wheel chocks.
You may give your vehicle a test drive afterwards then check if the U-joint strap bolts are still torqued properly. This is a general guide; refer to your owner manual for specific details that may require you to do this differently.
