Where to place the "Jack Stand" when jacking up a 2012 G37xS Coupe?

I have read the manual and it indicated the pinch weld as an area reinforced for weight support. However, wouldn't using the jack stand here cause too much weight on the pinch weld and result in bending it?

After searching online for more information, some suggested placing the jack stand on the frame rail. Then again, some have also said that this caused the frame rail to deform.

I did buy an rubber adapter for the jack stand but I was afraid even with the adapter I would bend the pinch weld.

What is the right way to use the jack stand and where is the right place to put it?

I jack under the front K member and rear diff. Jacks stands go under the pinch welds with a hockey puck in between. Puck has a slit so actual weight isn't on the pinch weld itself but the reinforced areas to either side of the weld.

Hello JSolo. Please tell me what the K Member is? I am no where knowledge enough and still learning my ends and out.

Also where can I get a hockey puck with that slit or is that something I need to have made?


Thank you!

My scissor jack states a 900KG max...thus the car weighs more then that. Any thoughts?

@G37xS-Life,

Search the forum. There's a number of threads on the topic already which include detailed picture.

@desertmike, only use the scissor jack (that came with the car?) for emergencies like changing tire on the side of the road. One corner of the car does not weigh 3000lb, or even 2000lb.

Here is a diagram of appropriate jack points:



Go to your local sporting good store and buy a few ice hockey pucks (make sure they aren't street hockey). Then use a saw, grinder, or any other type of useful cutting tool to cut slits down the center. You can find plenty of videos on this via YouTube. Really cheap and easy.

If you are looking to keep your car up for any length of time steer clear of the scissor jack its really only designed for a quick tire change. Invest in a nice 2-3 ton low profile floor jack. You can find some good ones via Harbor Freight. Then get some 3 ton jack stands to set the car on.

Thanks JSolo. I actually searched the forum and got mixed information. Some people have put the jack stands perpendicular to the pinch weld and this resulted in damage to the pinch weld. Others have put it parallel to the pinch weld, but on the inside and people have said that is just a plate and cannot withstand the weight of the car. So with that information, I am not sure what to believe and which direction to follow. If you know of a forum thread that shows a definite and correct approach; can you please point it out to me?

Thanks!

Also use this link Index of /FSM/G37/Coupe/2012

Its for the factory service manual, click on GI.pdf (general information) to download the pdf, then go to page 35. It gives exact lift points.

I can't imagine a jackstand placed parallel to the pinch weld. That's a crash waiting to happen.

I service several cars in the household. I took a different approach with the pucks as the pinch welds different in length between the cars. This will require 2 pucks for each stand. Cut one puck in half then screw the halves to the 2nd puck with ~1/4" to 3/8" gap in between. This gives a nice solid 1" deep gap for almost any pinch weld. The stand then goes perpendicular to the pinch weld with the puck in between.

Yes that makes sense! Duh! My OEM scissor jack seized on me, so I picked one up off of Ebay for a 2000 Infiniti Q45 that obviously states 900KG max vs the G states 100KG max.

So I took a look at the manual again, looked at the video link provided by JSolo and looked under my car a few dozen times this afternoon. It seems like the craftsman's 3ton jack Stand (sold by Sears) has a deep enough grove where if I place the jack stand perpendicular to the pinch weld, it would not make contact. However, I noticed that the side skirt would be compressed given how close it is to the pinch weld (on the outside surface). Would using the rubber adapter over the jack stand be sufficient enough so that the side skirt would not be damaged at the point where it makes contact with the jack stand and the rubber adapter?

i guess the instructions in the owners manual is just not good enough for some people.

I like to place the jack stands on the sub frame, but I guess the "safest" spots are on the pinch welds.

Thank you to everyone!

I was a bit nervous but I was able to jack the car and put it on a jack stand without bending the pinch weld.
