yeahhh, i guess this is true lol...but hey, what if the rear wheels are off

I use a hockey puck with my jack. I just cut a groove down the middle deep enough for the pinch welds at the jacking points. Works great and no bends

that's actually an awesome idea^

Interesting. I agree with the OP. Jacking points are one thing, but jack stands are a must if one is to be underneath. Secure jackstand points on the chassis are likewise a must. I will cut the underfloor cover in a heartbeat if it is the only way to obtain secure jackstand locations at the rear. Haven't had mine up in the air yet, but will definitely keep this thread in mind when i do.

Having attended one funeral for a friend who was in too much of a hurry to set a jackstand, I urge anyone who does not use them to re-think this.

ooo mana, sorry to hear that :-/

but yeah, not having a lift makes me very very wary of making sure the car is secure, but yeah, only takes a couple minutes, hardest part is taking the pieces off

haha

ooo i think i know what you're saying, yeah i bought a secondary scissor jack( like the one that comes with the car, lift it up a little bit at a time on each one just until the normal jack can reach, then it's smooth sailing

The problem with the rear is there are no good jack stand points on the car. Those pinch welds are not meant for jack stands. Even with hockey pucks and rubber jack stand covers. You will damage the pinch welds or surrounding areas. It really does suck and I wish there was a better way. I have had to just jack it up onto race ramps but now with my FI exhaust it's got harder as I cannot use the diff anymore!

I roll up on 2 - 2x10s and have no problem getting the jack under the diff with my FI exhaust.

I took a piece of 4x4, cut it to be 4x3 and I place that on top of the jack to sandwhich between the floor jack and the differential, seemed to work good when I used it. If the guy who installed my exhaust wasn't drunk, he probably would of been able to line up the pipes better and I could use a 4x4 instead.

Oh, and I built some ramps to drive up on, by using two 2x10's with 45 degree angles on them, screwed together. If I was going to do it again I might of used 2x12's instead.

Jacking it up on the pinch welds is correct but I was told and have always placed the jacks under the frame like some other members have as well with no issues.........

For added protection I just took a sheet of hard wood about 1/2" thick and cut it into 4 squares big enough that the jacks fully on the piece of wood as a base. This helps protect your drive way on a hot day if anyone has an aged driveway like mine! (the jacks will sinks in if its a hot summer day! I know i have the marks!) then I also had a 4x4 of hard wood and cut it down into 4x4 pucks about 1-2" thick and I put those on top of the jacks kind of like the hockey puck idea and in the end you can't even see one scratch on my from because there is no metal on metal contact to scratch it!
