Hi,
How do safely raise the front or back end of your G Coupe to remove wheels, do oil changes, etc ?
Do you use a ramp ?
Can you get some type of low profile floor jack ?
If so, what do you use as a jacking point ?

Thanks.

 

Supposedly you can use ramps, but my front lip hits my low-profile ramps. So I use a jack and jackstand.

There is a front/center jack point on the frame, that looks like a dog-bone.
The rear/center jack point is the bottom of th differential.

Not sure how well those low-profile jacks work, as usually the body of the jack is pretty fat with only the cradle being low profile. I had a floor jack that fit under the car fine, but the jack-handle would hit the front lip, so I would have to jack the car up with a screw driver for a couple pumps first. That was a PITA cuz there was no leverage.

So I bought an air-assisted hydraulic floor jack. The body of the jack doesn't quite clear the lower engine cover, so I have to back the car onto a 2X4 before I can get the jack under the car.... I'm sure they have jacks that fit better, but I like the air-assisted jack.

 

For the rear end, the differential is what you use as a jack point(be careful to use jack stands under the control arms as well so the car isn't teeter-tottering)

The front end can be a real pain to jack up, in my opinion, in comparison to the rear end. I use the factory jack to get it up off the ground and then use jack stands on the control arms to support it once it's lifted. Be careful though... it seems a lot harder to mount the jack stands securely on the front end.

If you don't need to take the wheels off and are doing a job that doesn't require you to unload the suspension, just use Rhino Ramps. They're black plastic ramps that are lower than normal ramps and dsigned to be used on cars with a lower ride height. They fit just about perfectly under the G35.

 

Ramps are dangerous and should only be used when there are two people
available....driver and spotter. It's much easier to use a floor jack (Sears)
and jackstands to work on your car. In your cars manual it shows at what
points to jack up your car and ALWAYS use jackstands, they could save your life!

LT1 SS ... thanks for that. Very helpful !
How did you get enough clearance to get the floor jack under the front end ? Did you back the car up on a couple of 2 x 6's ?

 

Great photos of jack positions. I use mini ramps to get started. http://www.discountramps.com/plastic_car_ramps.htm
Then I have room to move my floor jack under the car.
I got an Oak 2x4 and cut it into 4 pieces with slots cut into each one to fit on my jack stands and slip onto the thin metal jack sections on the side of the car as indicated in the manual and shown elsewhere here by Gordon Gee. Now it appears I don't need to use them anymore!

 

I drove the car on to some two inch slabs of concrete block i had laying around to get the floor jack to fit under the car. wood planks will also work

 

Great pics... now there is no question about the points.

 

this question has been asked so many times... first, there is a video on how to do this correctly here:

Of the jack points mentioned in the previous posts, some are ok, while others aren't. The definitive answer lies in the service manual. Here is the page out of the service manual that indicates the only places where you can jack the car up and be guaranteed no damage, safety, etc.
