Drivetrain noise

[aaronb]

Thanks for the replies. I also forgot to mention I replaced the torque rods and got an alignment 3 weeks ago. I just bought the truck from my boss in January. He had put 4 drive tires on the back axle when I bought it. I just replaced the other 4. I ran the 4 he put on for 30,000 miles with no noises. I put the other 4 on last Friday and then I Monday I noticed the sound. I can’t really hear the sound at 60 mph. I don’t know if it’s not there or if I just can’t hear it over wind and road noise. I can hear it from taking off up to at least 40. I’m going to check the u joints again and check the transmission and rear ends for any metal. I’ll grease everything up again.

I also forgot to mention. The clutch release bearing was getting noisy awhile back. I finally found the remote lube line had a hole in it where it went through the inspection cover. I fixed it and have been greasing it regularly and it seems to be fine.

I’ll double check the ride height. It does sound like a drivetrain alignment issue. It not doing it all the time has me confused. It doesn’t seem to do it when the truck isn’t warmed up first thing in the morning.
