The problem is you need to remove a very tight driveshaft nut on the newer model vehicles on the differential side. The old historic way of keeping the drive shaft in place by prying on it with a pry bar with your buddy is very dangerous and easily damage the driveshaft and its components.
The solution is the AGA Tools Drive Shaft Holder! The design of this Drive Shaft Holder is made to fit many different manufactures, old or new, because of the sliding mounts. The Drive Shaft Holder bolts directly to the center support using the longer bolts that are supplied.
Now removing the drive shaft can be a single man job!
