What is the cost for balancing my rear drive shaft. on 2003 Chevrolet Silverado 2500 HD

I was told by a mechanic that my rear driveshaft is out of balance. I took it in because when I drive around 62 mph and faster, the whole cab vibrates. I most feel it under my seat and center console. They said my U-Joints were fine.

Unless your driveshaft was struck by an object and dented,your mechanic is wrong. Get a second opinion. Is the truck a 4 wheel drive?

I don't know for sure on checking all of the u joints. I'm going by what he said and not by my experience. Yes the truck is a 4x4 also. What would the cost be to replace ALL of the U joints???? I don't have any tools to fix it myself. What else should I be looking at on the driveline to eliminate the noise. Oh, I have never heard any popping or clunking noises. Just the vibration only.

I agree wirh Parts Guy sure sounds like a locked u-joint. Did the person who checked it remove the shaft to test u-joints? Balancing a drive shaft went out 35 years ago!

You are correct wetry. There is a bad u-joint somewhere. My suggestion is replace all the joints.

Exactly, that is the only way to fix it! Just because a u-joint is good and tight does not mean it is good. Usually a gaulded joint is accompanied by popping and/or squeaking when accelerating followed by excessive vibration at road speed. This is assuming all other sources of vibration have been investigated and ruled out!

Take the truck to a repair shop have them pull the rear drive shaft out and check to see if the u-joints are DRY and gaulded. Replace all the joints in that shaft if defective.

you may just need u joints,that would cause this
