Hi

My drive slopes front to back no way round that unfortunately. So I use ramps and chocks where possible, if not axle stds and chocks.

What irritates me is my current car (94 merc SL) has nowhere to put the axle stds except under the jack pads (quite secure when up)

So to jack it I have to remove the jacking point covers and use the car jack rather than my trolley jack. This never feels very secure (kind of push's the car sideways) until safely on the axle stds.

This got me thinking, why not have a jack with a wide base and locking pin? Does anyone make such a beast? I appreciate I would have to have two which would make it expensive.

I have seen things like this in use under 4WD vehicles & farm vehicles, alas they would not get under your car, don't know of anything off hand that would do what you say on your car.

Can you use the suspension mounts as another place to Jack from? My car has nice solid plates around the wishbone mounts.

I've used suspension mounts on other cars, the undertray gets in the way on the SL. frown and it's too low to take the undertray off 1st.

The two safe places to jack are the diff (I don't like this) and a plate behind the engine, to lift either end of the car. I don't like to this whilst jacking on a slope it doesn't feel stable.

I'd love a pit but my garage is too narrow for anything except a Midget (and that's a bit tight)

I'm forming a design (in my mind) some sort of cantilever frame arrangement, with a wide stable base and a flat plate with a cup on top. Use trolley jack inside the framework to jack, Lock cantilever, remove jack and move around to the other side.

You could even jack each side a bit at a time (to keep it stable) and get a decent working height.

idea
