Need help diagnosing vibration
Vibration started about 5 months ago. Last repair I had done before that was new rear brake calipers.
Vibration only occurs at speeds over 55mph, most pronounced between 65-70. The dash rattles, floorboard vibrates, etc. It's felt all over. Things I have done with no resolve: new tires removed front drive shaft and drove replaced both U joints on rear drive shaft.(the said it was balanced but I don't know that they had the equipment to do it?) If you left off the gas and coast at 750rpm's, the vibration remains so I don't think it's related to the engine. The vibration feels the same speed as the drive train. If you hold on to the 4x4 shifter, you can feel the vibration there. I just don't know what else would be vibrating? I suppose I could remove the rear shaft and drive it to see what happens. Any advice? thanks, -

driveshaft could be positioned wrong, i've actually had this problem on my fathers dodge, take the driveshaft out but mark it on the transmission side. put the driveshaft back in 1 or 2 notches from either side of that mark. i played with that until the vibration went away.

If you say you can feel it in the t-case shifter really well I would check the t-case out. Might have a chain that is loose or something like that. -

a friend of mine's f-150 had the exact same problem. it started around 55 and got worse the faster you went. so it was obviously rpm dependant. the 4x4 was actually trying to engage and was about $900 to fix the grinded teeth. -

Thanks for all the suggestions. I haven't had much time to check each one but I'll get there. It is a frustrating deal. -

I agree with the other guy, these transfer case chains get loose and then they vibrate. Also, if this started when you did the rear brakes, put your truck up on stands and let someone put the truck in gear (while idling) and see if you have a wheel on crooked. The rear wheels go on and off really tight and the mounting surface has to be clean. It is dangerous so I wouldnt do it yourself, have someone sit in the drivers seat just incase. -

Subscribing. I have the same thing and replaced everything in the hunt with no luck. EXACT same symptoms. the only thing that has fixed is when I run stock tires. I'm curious to know what size rims and tires you have. I'm suspect its a wheel bearing issues due to tire mass or my 40" tires are out of round. This is what I have replaced in the hunt without improvement: 4 new rims rear drive line ujoints rear drive line carrier rear drive line balanced front drive line ujoints front drive line balanced entire new trackbar entire new tie rods new front axle ujoints new front rotors front end alignment front ball joints 3rd gen gear box stabalizer -
