Went for a high speed run late last night (100 mph) and I looked at my shift lever and it was just shaking all over the place. A bit unsual as it has never happened to me before.

I'm lead to think it's the driveshaft or maybe a tranny/engine mount.

My car is lowered with Tein RA's about an inch all the way around. I mention this because I remember reading something about lowered cars stressing the driveshaft? Is this correct?

 

You may simply have a case where your car has reached an age now that your motor mounts aren't as stiff and they used to be. Any 4 cylinder engine with no counterbalancer has naturally high vibration levels. Some car makers use counter balancers, some use rubber mounts, some use vibration dampers (like the crank pulley on the S).
You may just have a case where the vibration dampening devices have aged and you see more evidence of it in the shifter. You may also have other imbalances such as wheels/tires, propshafts and 1/2 shafts that are adding to the existing vibration.
Technically, a lowered S alters the angle of the 1/2 shafts. This can induce a different kind of wear pattern on the CV joints. They make spacers that supposedly correct for this anomaly.
Finally, 100 mph on many roads at this time of year can be a very rough ride. You've just come out of your rainy season (like I've just come out of our winter season) and roads tend to develop more irregularities.

 

Exactly what the two girls in your avatar should do:
Shake It Baby!


Maybe check / regrease the nylon? pivot points of your shifter.
Cheap to replace if worn / broken.

 

Thanks xviper. Would one of those engine dampers under the hood that mounts on the side of the header help any?

Does this mean it's time to replace the mounts?

 

They do, on a regular basis

 

You're talking about an engine damper. No, this will only aggravate the situation as it will prevent the engine mounts from doing their jobs as well as they should.
Don't know if you need new mounts. They don't generally need replacing unless they leak. You should investigate those other possibilities first, like the road condition where you drove.

 

Thanks again!

As if you actually know those girls....

 

So has anyone ever had to replace the engine mounts? Because my shift knob does the same thing, but pretty much all the time.

And i noticed my passenger side engine mount is BYE BYE. it looks like some raised the engine up out of it and then placed it back on there. BAD. But i wasn't sure if i really needed to replace it?!

What/Where are thoose?

 

There have been several owners who have had leaking mounts and had to replace them. It's not that bad of a job and the mounts aren't too expensive.
But before you go out and pay for new mounts, make sure they are actually "bad". It may just be a matter of improper placement and installation. You should also check to make sure the rubber tranny mount is secure.

Greasing the pivot point involves removing the console around the stick and partially disassembling the base of the shifter and applying grease to the ball and socket at the bottom.
