Default using floor jack raising vette

I have a 69 vette, and is it al right to lift car from the big crossmember in front of the car, and can you use the rear crossmember as well.or are you just supposed tolift from the fram rails on the sides, I have a car with side pipes and what a pain to get a jack under it that way.you guys on here seem to have all the right answers.thanks.

I lift the front under the front crossmember but be careful to not dent the crossmember(the steel isnt that thick). I lift the rear under the diff but I find i have to put a block of wood on the jack so as to not damage the spare tire carrier(I guess it depends on your jack).

You will find threads about people having to repair dents in the front crossmember from jacking, personally I wouldn't risk it and I always jack from the frame rails as suggested by the handbook.

GM recommends not jacking the car under the front crossmember. Use the standard jacking points.

Use a one foot long piece of 2x6 lumber as a cushion. Run it front to back and make sure it over-laps the edges of the crossmember. Same with the rear, use a piece of 2x4 under the differential that covers all the spring bolts.

Build yourself a set of ramps. No jacking at all unless you need to do Wheel work.

See my profile for examples.

Here's the bottom of my front cross member which clearly shows what can happen if it is used as a jacking point. DON'T DO IT!




I cut the section out and restored it... installed vertical ribs inside now, so could be used as a jacking point now.

I bought one of these from Harbor Freight. Decent quality for what it is. The main feature I wanted was how long and low it is.

This is what I do as well. My cross member is already caved in from PO's using it as a jack point and not using a piece of wood.
It's a whole lot easier if you use a low profile long handled jack like the one ts_vette_st pictured.
I also built a ramp of sorts that I park on each time. It's just two pieces of 2X10 screwed together one about a foot longer than the other, maybe 28" in total length, then I can drive onto it 1 1/2" at a time. Puts the wheels 3" higher in the front making it easier to get the jack into place without hitting the air dam. If you have the capability a 45* angle on the front edges of the 2X10's helps the tires go up onto the boards.

Here are my ramps. Home built using some Rhino Ramps, scrap lumber, liquid nails and lag screws.
I use a garage-sale mirror to watch my tires as they go up. I then detach the eye hooks to remove the ramps so I can work under the car. I then raise the rear with a floor jack and put it on jack stands.
You can add 2X10 pieces to get it higher if you like.
