I have posted this before, but a while ago. I have a rumble (almost like bad u-joint's) when I reach 60-65 miles an hour an higher. above 75, it seems to either go away, or I just can feel/hear it. It hasn't seemed to be doing it when I ease off the throttle until tonight.
I had my tires rotated and balanced, and had the u-joint's replaced, but it's still there. Any ideas? I don't want this to turn into a prblem if I can stop it quickly.

Describe the rumble. More info would help understand better.

it's actually more of a vibration then a rumble. It feels like u-joint's but it can't be 'cause I just replaced them about 9,000 miles ago. It doesn't feel like it's coming from the front end.

Yeah, the rear driveshaft u-joint's where the ones I replaced. I haven't changed the rear diff fluid yet, but the level is good.

Is this a physical vibration or just like in your ears. Thes trucks tend to have a drone from the engine close to the speeds that you are describing

Well you repalced the rear u-joints but what about the front? Front drive shaft, and 4-wheel drive shaft u-joints on either side. I'm having my driver side replaced u-joint replaced as we speak. How many miles on your rig?

It's deffinately a physical vibration.
Ram-it: I haven't replaced the front end u-joints yet, pretty sure it's not in the front, tho. I've got just over 84,000 on my truck.

Could be a bad carrier bearing on the rear driveshaft
