my '95 GSR has some vibration issues. Something up front vibrates pretty hard at around 3000 to 4500 r.p.m. It does this is 2cnd -4th gears, but you feel it mostly in second. This is annoying the crap out of me!

I did replace the front left engine damper mount on the bottom. I looked at the one on the right front bottom and its cracked. I also replaced the half shafts with aftermarket pieces. Any ideas?
