Hello All, I would like to pick your brains. I have gotten a lot of good info here in the past and I'm hoping one of you can help again. I have a 1994 Ram 1500 4x4 with a manual tranny.
I have a noise that is worrying me. It has gotten progressively louder over the last month, and I'm not sure what it is. It sounds like a winning, howling sound that seems to increase in pitch with road speed. It's the loudest between 30 - 40 MPH, but can be heard slower and faster. Sort of like tire noise, but I don't think it's the tires. The tires are only a few months old and I suppose it could be them if they get louder as they wear. I did not hear the noise at all when the tires were new and it's pretty loud now (about 6000 miles). I also replaced both front hubs and axle joints over the summer, about the same time I put the tires on. I don't think is the transmission, the noise does not change when I push the clutch IN, put it in different gears or even coast in neutral. The noise doesn't seem to change with load either. I even put the transfer case in neutral and ran the tranny through the gears with no noise. I replaced the rear u-joints and changed the fluid in the transfercase and front differential with no change. Last week, the right front axle seal started leaking pretty badly, but I have no idea if it's related. I replaced the axle seal over the weekend, but have only test-driven it sence. The leak appears to be fixed but as expected the noise is still there. Any Ideas?
