Sometimes the yoke and centre bearing can be hard to remove, this is when you will need to use a hydraulic puller.
Step 1. Use the puller to remove the outter housing and rubber part
Step 2. Use the puller to remove the metal bearing
If it still wont come with a puller use the oxy (gas torch) to heat the bearing while you have pressure on it with the puller and if that still doesnt work use an angle grinder or gas torch to cut it off being very careful not to cut into and damage the driveshaft
