Well I asked before but I still didnt find out why my car is vibrating??? 
Awhile back, I would say about a month or so ago I did a 5-lug sonversion on my car with 95 gt front brakes and 87 ranger axles w/drums.... After the swap for a couple of days it was running the same as it did before the conversion!!
One day when I was going home from school I was cruzing in 5th then I went to 4th to get ahead of traffic then all of a sudden it started vibrating??ever since then its been doing that... From 3 gear at 2200 to 5th gear cruzing at 2000 it vibrates... The vibration feels like when you have it in 2nd at a stop then you go slowly you have that vibration that the car is struggling.... any suggestions to what it could be?? Im lost.... Could be the Harmonic balancer
