The transmission system yoke links the driveshaft to the transfer case, securing the back of the transmission and acting as a driveshaft mounting point. It works along with the splines to let the driveshaft move freely.this can be in and out or up and down. As the axis changes, the length is adjusted as well. As a result, this mechanism allows for the transition of transmission torque to go smoothly. Transmission performance can dip to an unexpected low when this part finally succumbs to wear and tear. The driveshaft can suffer greatly from this. So once it has reached this point, the damaged part should be fixed right away. Look for a replacement that's specifically engineered to match the OEM specs for direct fitting and also one that's manufactured from high-strength materials for utmost durability and reliable transmission performance.
Tools and steps in replacing this transmission mechanism
When replacing this transmission part, you'll have to remove and install a new drive shaft assembly.
Difficulty level: moderate
Tools needed for this project:
- wheel chocks
- handheld sledgehammer
- replacement drive shaft assembly
- vehicle manual
- 1/2-inch drive socket set
- 1/2-inch drive ratchet
- torque wrench
Note: For your protection, make sure you have safety glasses on.
Prepping up for installation
Park the vehicle on a level ground. Make sure that the engine has been cooled before you start. To keep the vehicle steady and safe, wheel chocks should be placed in the headmost part of the front wheels and positioned at the back of the rear wheels.
Removing the yoke
This mechanism can be found at the back of the transmission. This is attached to the driveshaft's front part. Once you've located this part, you have to crawl under the vehicle to remove the U-joint cap bolts. A ratchet and socket can be used to loosen the bolts.
After removing the bolts, move on to pulling back on front driveshaft yoke. If some components are stuck, this can be fixed by using a sledgehammer. After this, you can now pull out the driveshaft's front part. The U-joint strap bolts should be removed with a ratchet and socket. Finally, disconnect the rear-end yoke on the driveshaft rear. Use a sledgehammer for stuck parts.
Installing a new driveshaft assembly
To install the new driveshaft assembly, you have to start by sealing the driveshaft's front part U-joint to the yoke that's located behind the transmission. The straps of the U-joint must be laid onto the said part. After this, you have to secure the strap bolts into it. Use a ratchet and socket for tightening the bolts. The strap bolts should be torqued using a torque wrench and a socket. For best results, make sure that you consult the owners manual first and follow the manufacturer specifications strictly.
The same steps should be done for the one in the rear driveshaft and the rear end.
Testing the installation
After installing the new part and removing the wheel chocks that keep the vehicle from rolling, take your vehicle out for a spin. Take note of any irregularity while the vehicle is running. After the test drive, inspect the U-joint strap bolts to see if they are still torqued the right way. If not, make the necessary adjustments.
