Default How do you 'properly' use a floor jack? Seriously!!

Well I know how to use floor jacks for many years. But now do you properly use it on our unibody Zs so we don't end up bending and messing up the 'tab' at the jack points under the car?

No matter what I do they get bent and end up rusting. I would use pliers to straighten them...only to have service shops or mechanics mess them up again!!!

Is there another better point to lift the car from?

There's actually a special adapter that you use on the jack pad that straddles the weld flange. I made my own out of some 4"x4"x1" hard rubber blocks. I cut a 1/4" groove across the face of one side of the block. That groove slides over the weld flange and I place the jack under the pad and lift from there.

In the diagram above, the "garage jack points" are where you can put a floor jack for lifting an end of the car. The rear is no problem, the front requires you to drive up on a small ramp to be able to fit a floor jack under the car.

For me, it just depends on what I'm going to be doing. Sometimes I use the side lift points, sometimes the center points.

Just don't forget to use jackstands. That's where the rubber blocks come in handy too. You can also buy adapters for jackstands that fit over the weld flange.

I made adapters out of hockey pucks with a cut across them.

thanks guys, you all have very creative and great ideas. I may use your ideas and create my own adapters. I may also look into Griott's Garage low profile floor jack or ramps.

This is The jack I use, and I love it. even with my car as low as it is I can slide it under the front bumper and jack it up from the cross member like the FSM States.

Wow it doesn't look like it's that long from the pictures. May have to invest in one of those.

its a truly awesome jack, I have friends with stupidly rediculously slammed 240's (about an inch of clearance from the ground or 2 lol) and I just gotta use a 2X4 or 2 to get my jack under it.

How low is your car? My car is lowered a bit and I have about 4" clearance from ground to lowest point of the chassis.

Seems like a good jack for the money considering the one offered by Griott's Garage is $400.

Minimum lift height for this jack is 3.25", but the back half of the jack is quite a bit taller. Curious if you vehicle is lowered. thanks

This one has worked well for me. Doesn't lift "high up" but high enough to get under the engine and do any required work. Further, it slides just far enough in to fit right under the center jack point w/o any special finagling. Of course - always use jackstands too and don't trust a car w/ a jack alone (honestly I don't even trust jackstands and typically place addiitonal support under parts of the vehicle):
