DriveTrain Vibration

Was having some serious thunking going on recently when taking off hard on dry pavement. Now I'm getting a high frequency vibration between 48-56mph. When you let of the throttle it stops and as soon as you get back into it the vibration starts again. Just started doing that this weekend while I was pulling my snow machines back from the cabin. Was thinking carrier bearing for the thunking and maybe for the new vibration. It's an '02 F350 psd crew cab short bed.

Cool vibration

I was going to ask both the above. My sons super had dry joints in the front. He has a big lift but it never vibrated until recently.My X has only 8" lift and vibrates between 53 and 68. I think I can fix that now, It need's to have a cv joint like a superduty.

Check for play in the end of the transmission. Just take your driveshaft and try to wiggle the yoke up and down and from side to side. Could be the bushing is wore out. I had this happen on my explorer due to running Swampers

knock knock!! clank?

first off, a high frequency vibration will be driveline. how ever you cannot check U-joints properly while "wiggling" your driveshaft... yes to much angle will cause vibration with I.E. lift kit... but in order to check your SHAFT/joints you must take the shaft out and then wiggle your joints. your joints can actually be bound up to where they will still cause vibration but will still feel tight. bent or dented shaft will do the same!

The wiggling is to check the bushing inside the tail of the trans. I have had this problem before and a tech of 17 years showed me this trick to checking the bushing. I am not sure if this is his problem or not but I thought the advice would be helpful in trying to diagnose this issue. If you have up and down movement then it is probably the issue. The yoke should fit snug inside the rear with no movement. The actual vibration caused by my swampers is what started to eat away at the bushing and it just got worse from there with time. It ended up being horrible and I could not figure out what is was. It only cost me 10 bucks to have a new bushing pressed in.

the carrier bearing will generally not cause a "thunking" noise, and usually doesnt cause a vibration that comes and goes...they usually come in at a certain speed and get progressivly worse. i would look at two things for your vibration, assuming you were not in 4x4 when you noticed it, because that will cause unualual vibrations in itself due to all the extra metal turning. first off, pull your driveline all the way out and check the u joints for any play or signs of binding when you turn the yokes, and also check the slip yoke if it is a two piece shaft. i would also consider the vibration as being a tire balance issue. a lot of times if you throw a wheel wieght, you will get a sudden vibration, and you can usually "drive through" an unbalanced wheel, meaning after a certain speed the vibration goes away again. look for any place on your wheels where you can see the residue where a wieght used to be and now is not. as far as the clunking noise, i would have to have more info to help you with that. hope this helps

I did not see anything about "thunking". Sorry for the bad advice then. Yeah mine would start around 50 and would continue to get worse the faster you went and it was consistent. The way he had me test it was to drive about 80 where I felt the vibration really bad and then put it in neutral to see if it went away. Don't know if it is the best way but it worked for me.
