For removing and/or changing your tires, the Powerbuilt Unijack claimed to be safe and easy to use. Unijack lifts both body-on-frame and unitized (frameless) vehicles at the factory-approved points and also locks at the desired height, thus eliminating the need for separate jack stands. The 4,000-pound capacity Unijack has a lift range of 8 5/8 inches to 18 3/8 inches, and is capable of lifting a variety of vehicles, from compact sedans to minivans and utilities. It also works on a variety of hard and softer surfaces, owing to an extra-wide base. Get full details at www.powerbuilt.com and purchase for about $70 from www.amazon.com.
