Welcome to FWD! A lot of people have disconnected the propeller shaft because of a failed bevel gear. I doubt the VC had anything to do with your problem.

The main gear of the bevel gear is press fitted onto the shaft. The splines on the shaft are a very weak material and cannot handle a lot of torque. This usually occurs on the R models sooner than the XC. Removal of the propeller shaft eliminates any torque on the bevel gear.

Some have gone so far as to spot weld the bevel gear on to the shaft to keep it in place. It is THE weak spot on the AWD system, and continues in the new models. Replacing the drive oil helps because it keeps the oil temperature down, but that won't help you.

Now that you are FWD, your steering will feel lighter and there will be more torque steer. You will also get better gas mileage and you don't have to worry about replacing all 4 tires at the same time.
