You can save money by building your own dolly, but Year Ones dolly is certainly affordable.
Hot rodders love to collect parts. Some of the most desirable parts are rearend assemblies. But what do you do every time you need to move that 12-bolt axlehousing to the other side of your garage? Unless you're built like Herman Munster, moving that third member can require serious effort, especially if you are by yourself. Fortunately there are a couple of easy alternatives. The folks at Year One now sell a versatile rear-axle assembly dolly that retails for just under $100. The dolly can be used to support any type of passenger-car rearend assembly and is certainly safer and easier to use than your floor jack.
The dolly is constructed of 1-inch square tubing and uses four casters. To prevent the pinion from rotating downward, the dolly features a pinion-support bar welded across the assembly. The dolly with casters measures 2 feet long, 13 inches high, and 14 inches wide at the base.
If you're more resourceful and have access to a MIG welder, you can pick up some 1-inch box tubing and a 3/16-inch metal plate from your local metal-supply yard and build your own. Just cut the box tubing and metal plate into the appropriate sizes and weld it up.
