Hi all,


I have a 1980 dodge ram b100 with a slant 6 225 with a 4 spd manual transmission. When I reach speeds of 80km/h or high the whole van will violently vibrate and get worse as you go faster. I notice it gets extremely hard to get past 80km/h, as if I lose enough power to accelerate further. Doesn't matter what tires I have or what gear I am in. After a while my engine will stall (flood).

Anyone know the cause of my problem?

Thanks!

Worn u-joints will cause this.
