The Eastwood Hydraulic Wheel Dolly 4-Piece Set is primarily designed for short-term vehicle movement and positioning within a garage or workshop. While these dollies lift the tires off the ground, potentially reducing the risk of flat spots, they are not explicitly intended for long-term storage. The manufacturer's guidelines emphasize their use for moving vehicles around the shop and advise against operating a vehicle while it's on the dollies.

The Eastwood Hydraulic Wheel Dolly comes equipped with heavy-duty ball-bearing casters designed for smooth movement on most paved and concrete surfaces. However, the context does not provide specific information about replacing the rubber wheel casters with metal casters. Therefore, I cannot confirm whether such a modification is possible or recommended. If you are considering modifications, ensure compatibility with the dolly's design and weight capacity.

To add hydraulic fluid to the Eastwood Hydraulic Wheel Dolly, follow these steps: Prepare the Dolly: Place the dolly on a level surface and pull the rollers fully apart. Locate the Oil Fill Plug: Find the oil fill plug, which is a Phillips head screw located on the side of the hydraulic cylinder. Check the Oil Level: Remove the oil fill plug and observe the oil level. The full oil level should be even with the bottom of the fill hole. Add Hydraulic Oil: Use only high-quality hydraulic jack oil to avoid damaging the hydraulic pump seals. Using a small funnel, carefully fill the cylinder with hydraulic oil until the level reaches the bottom of the fill hole. Reassemble: Replace the oil fill plug securely. Caution: Avoid using any other type of oil, as it can seriously damage the hydraulic pump seals .

That should not be a problem especially if you let the dollies back down on the safety pins when in storage to take the pressure off the hydraulic pump.

The minimum would be to put these just under the drive wheels. If the vehicle is RWD and you are able to unlock the steering column, 2 of these under the rear wheels would work for your purpose. If the vehicle is AWD or 4WD then you will need them under all 4 wheels. If the vehicle is FWD you would put them under the front wheels but depending on how you need to maneuver the vehicle you may want use have them under all 4 wheels.

While technically, these could lift a motorcycle, I would not recommend trying to use this with a motorcycle. It would be difficult to balance the motorcycle on these and potentially unsafe to attempt to do so. I can't think of any safe way to do that.

These are only designed to lift the tires just off the ground enough to be able to roll the car around. Approximately 1/4-1/2 high.
