Need some ideas on where to go next.
A couple of weeks ago I started hearing a noise while the truck is moving. Noise changes pitch as speed increases. Thought it might be wheel bearings. A buddy stuck his head out as we went down the road and he thought it was in the rear wheel. So, I replaced the rear wheel bearings and still had the noise. I did the front inner and outer bearings Friday night and still the noise. Where to next ?? Transmission, Clutch, U-Joints??. Clutch replaced 15 k ago, U-joints less that 3k. ANY IDEAS welcome.
