Sidenote: This is my first post, I've already tried searching the forums for this problem.

I own a 2010 G37s Coupe 6mt. Recently I've been having a strange problem. When accelerating (above 4000 rpms) I notice that my shift **** shifts to the right very violently (when I'm in gear). Along with this, there seems to be a squeaking noise (similar noise if you rub a finger against glass) coming from what seems to be the front. This sound also erupts when I put just a little more gas (1300 rpms) than usual when driving off in first gear. I have a feeling this might be because of my shift linkage.

Also: When I turn left, there seems to be a loud popping noise coming from the front drivers side of the car. I took my wheel off to try to diagnose this problem but I did not see anything wrong.

Any help would be greatly appreciated!

 

My first thought is broken motor mount.

 

I will look into it to see if the engine moves when revving. Thanks!

 

Update: Not my motor mounts, the wobbling noise and shifter shifting to the right in gear have both stopped strangely enough.
But I get a popping noise coming from the front when flooring it 1st and 2nd gear. Doesn't happen when in 3rd gear and so on. I tightened my sway bar end links but still didn't fix the problem.
Anyone have any similar issues?

 

Try manually shaking your motor. Like grab a hold of it and man handle it and shake it. On my g35 I had a bad motor mount that only made noises when going over speed bumps, heavy acceleration, and shaking the motor. Reving without Load didn't make a knocking noise if I recall.

 

Tried shaking it by hand, motor would not budge. This noise only happens in 1st and 2nd gear. Car has 60k miles on it if that would help.
Thanks for the reply though!

 

Check trans mount

 

The trans mount has soft rubber. You'll probably have to remove it to see if it's bad.

 

Anyone have instructions on how to replace the trans bushing? I checked z1's website and they said instructions are set with the product.

 

It's all of four bolts. Two mount-to-chassis bolts and two mount-to-trans bolts.
