Okay my dads 99 has a vaccum disconnect on his front driveshaft so it doesnt spin in 2WD. My 02 however as we all know has some great cost cutting features such as no front disconnect. I have a skyjacker 2. 5 inch lift and have the 75 mph vibration. How would i go about getting that driveshaft to stop spinning short of stealing the old mans front axle.
