viberation
 

I have an 85 with new front springs and shocks, the rear has new shocks and fair springs. Tires are fairly new. Im getting quite a bit of viberation when Im at 55-60mph. Im not sure if its the driveshaft u joints or what. It does have a little sqk when takeing off from a stop.

Is it worse when you're on the gas? If so, probably u-joints. If not (it's the same whether under power or coasting), then probably tire balance.

vibration
 

Yes it is some what worse when on the gas. When I push in the clutch the vibration is not there
