Jack Stand Question

axio · 07-24-2009, 02:58 AM

The hockey puck... I was able to not bother cutting a groove in it for the pinch rails. The pinch rails will kinda cut into the hockey puck anyways and the hockey pucks are actually quite rubbery and will compress and bend a bit.

BTW, i just checked right now since I need a new jack cuz my old Kragen jack started to squirt out jack oil when I was lifting the Z up the other night to put in the sway bars, but with the hockey puck acting as a cushion for the pinch rails, the minimum jack height on a stock Z with the sport package tires is about 5.25". That's for the front pinch rails. I forgot to measure at the rear pinch rails, but i'd guess they're probably similar.

Safety note: Whether using two or four jack stands, always give the car a good shake to make sure the car is sitting solid on the stands before crawling under. I also leave the floor jack under the car as a back-up should one of the stands fail for some reason.

I think there are only 4 jack-points listed in the manual - if you're putting the car on 4 jack stands...where are you putting the jack?

In the manual, there are actually 4 jack or jackstand points (the ones along the edges of the car which require the special emergency jack, or something to adapt it for use with a normal jack or stand, like the hockey puck thing), as well as two lifting points (one in the center rear, one in the center front). The confusion comes from the fact that of the first 4, they only show a picture of the two on one side of the car, the other side of the car is implied.

But in any case, there are other valid points to place jackstands, you just have to make sure that you place them at structurally sound places (so that the weight of the car doesn't destroy the car part the jack or jack-stand is hitting), and that the car is stable when you're done (as above, make sure it doesn't shake or tip easily, and a backup jack isn't a bad idea either).

Do you have any info on the center jacking points? (unless it's in the manual and I missed it) - I'm thinking those are what I'll use, then drop the stands under the recommended points.

Hockey puck eh? I guess that'll work.

They're in the manual in the GI (General Info) section. There's pictures of both the side-edge stand points and the center jacking points.

Yeah a hockey puck with a groove carved in it.

Thanks, I'll check it out when I get home.

I meant the Service Manual of course, not the owner's manual you have at home. It's posted here in PDF format, in the forum about service manuals

My stupid jack doesn't go high enough to really do anything more than an oil or tire change....doh!

Looks like bolt-ons will be a chore for my mechanic.

wstar- could you post a copy of center jacking points?

spearfish25 · 07-24-2009, 07:43 PM

Here you go...

Am I correct with what I think I'm seeing - the crossmember under the engine is the front jack point, and the differential is the one for the rear?

GMZ · 07-25-2009, 07:08 PM

I just had a fun time changing my oil today. My ramps were getting pushed away by the bumper and the jack I have wont fit under the sides so I had to use the e-jack and throw some jack stands under there. I def see a scissor lift in my future!

As for installing a cat back the easiest thing other than being on a lift for me was I back the car up with the rear wheels on the ramps, then chock the fronts and go at it with a crawler.

ive been using the Diff for the back, i was curious where the proper front jack point is.

kannibul · 07-26-2009, 12:08 AM

I tried getting my jack under the car this evening (finally!), and no go.

I guess I'll just get me some ramps. I can load those in the front, and jack up the rear if/when I do an exhaust swap.
