I have been bombing around in my 88 since I had the 3.73's put in a couple months ago and not noticed much in terms of bad vibes untill tonight. I had her up on the highway for the first time since the install and got to say once I crossed passed 63-65 mph+ the ride became kind of ignorant. The shifter was shaking (but it does that pro-5.0) but there was some serious noise coming from the shifter and vibes from what seemed like the drive line. With gas pressed the car shimmied but it did not transfer up the wheel you could just feel the shake, and when the clutch was engaged off the gas there was still some serious noise and vibe untill I droped below 60 mph again and all was well. What causes should I be looking for..here is what I'm thinking.
1. Bad wheel bearing
2.bad motor/tranny mount
3.drive shaft
4. rear end..but runs fine at lower speeds fairly quiet for having gears
5.crappy tires..but didn't notice vib prior to gear install
6. help me figure this out.
