hey guys, i need help. here recently when i get up to about 35 i get a bad vibration from the front right of the truck and it gets harder the more speed i gain. (i think its the front right but im not 100% sure.) and whenever i let-off the pedal it stops but as soon as i give it gas it starts right back. and if i remember correctly once i get over a certain speed it stops, not sure about that because i dont remember but i think it had stopped. what do yall think it may be? its driving me nutz not to be able to drive my truck anymore (i just got a mossy oak steering wheel cover for x-mas ) by the way it is an 89 jimmy if that matters any. and thanxs for any help yall can give me.
