My 1990 ford f150 just started vibrating going 55mph. It's like when you drive over rumble strips on the side of the highway! Anybody know what's going on?

Maybe a carrier bearing on the driveshaft?

Rednecker

It might. I dont know yet, I brought it to the shop today to get it inspected and I told them about it so tommarow it should be fixed. If not i can probably fix it.

Strange how it all of a sudden started doing it. Um I had a similar issue. Just a different speed my vibration was at 75mph I corrected it by removing my drive shaft and turning it 180 degrees. It's a 2 piece drive shaft so in the middle of disassembling it I though to my self well this might be pointless but I did it anyway and it actually did it. Maybe the shaft was off balance. I still have no clue but it did fix it.

I might try that! Is it only this model ford that does it or what?

My front end was doing that, I replace the tie rod ends and ball joints and then it quit. I do t know if that sounds like your problem but I had that same symptoms

i think I applies to anything that has a one piece driveshafts, surprisingly enough it worked on my 2 piece.

My truck once vibrated horribly on the interstate, I had mud stuck in the backs if my rims. Even after I thought I got it all out, it vibrated. I just didn't get it all out lol.

Did you ever get your truck fixed? I was curious to know what the problem was...U-Joints?

Rednecker

No I haven't fixed it yet. I think it is the transmission not shifting right. If I let off the gas and then hit the gas again it stops vibrating.
