Default Rear Gear Info?

I picked up a 07 5 speed car today from a used dealer. The car has 2k miles and is untouched. The window sticker is gone and I was wondering if anybody knew a quick way to check the rear gear ratio? I know you could order 3.55 gears. Thanks in advance.

There's a little white sticker on the rear end housing, that will tell you what the Gear Ratio is. However, be advised that some Guys change the Ring and Pinion Gears, without changing what the Sticker says.

If you have a tuner it will show what is installed based off the gear ratio for the ECU. Or get under the car and look for the sticker on the girdle like everyone else has mentioned! I read that auto's have a 3.31 if stock and sticks can have 3.55 gears. I know you can get it upgraded from the factory though so I am sure it is one of those sizes

When they replaced my factory 3.31's with new ones they just wrote 3.31 on the diff. with a grease pen.
It's gone now!

Actually the sticks has the option of 3.55's in 07. So yes, if it is stock. Its one of those 2. But thats not really set in stoneabout which tranny/gear it has.

Not me, if I ever trade the car in. The gears will be in it, but the Xcal won't. So thats there problem to fix. The dealership can fix it with a little computer fix.
