Here's the problem. Trolly and floor jacks are intended to be used on hard, level surfaces. It is dangerous, and sometimes impossible to use them on any other surface. > >Should I get the cheaper no-name made-in-China's, or >the more expensive brand-name ones (which may also be >made-in-China :-)? > >The Haynes 9000 manual says that the proper lifting point >when using a hydraulic jack is in the CENTER (of >the front or rear end).

The problem is that using the side lifting sockects for a floor jack will damage the side-jack mount, and will also not provide a suitable stable contact point for the jack head. You can do what several SAAB shops have done, which is to weld together (from an old jack) an adaptor. (Essentially, you weld the old jack head onto a 1/4 steel plate, that has a diamond-mesh screen welded to the reverse side.) I'm not sure what the issue is here. The hand crank jack (properly lubricated) is pretty easy to use.
