weird vibrations in the front

[89coptzer]

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.

are the hubs engaged? Transfer case? What is the tire condition like? Those are the things I'd be looking at right off the bat.

well it has the automatic locking hubs and it is in 2 wheel drive. and the tires are in good shape.

Have you been mudding recently and still have some stuck on the backside of the wheel??

nope. i also thought that the tire may be out of balance but i put the spare on and got the same results
