Vibration when accelerating

[BeatDaSHO]

Question for you guys. I have an 89 SHO and during acceleration in 5th gear going 70mph, the car shakes. I think the shake is coming from the front. It's not too noticeable but it's definitely there. The shake becomes more apparent as you go over some bumps as the car goes up and down while accelerating. The car drives perfectly smoothe and it's only during acceleration at higher speeds that it vibrates. Also, as i'm accelerating, the car pulls to the right and as i let off the gas, the car then tracks to the left. I noticed the tracking issue after replacing the lower ball joint and this is when the car started shaking as well. I had it aligned but no difference. I know the left front strut bushing needs to be replaced but i wouldn't think this would cause this and it's not that bad. Maybe i'm wrong? I have replaced in the last 5000 miles; reinforced front and rear motor mounts, aluminum sub-frame bushings, drivers lower ball joint, both half-shafts, and inner and outer tie rods. Any idea? Thanks.

I don't necessarily think this is the problem...but why didn't you replace the passenger ball joint - that might be a possible problem though. With the new parts it is being magnified.
