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?
