I have a jeep cherokee sport 2001, 4 wheel drive, strait 6..
I had a humming sound in the rear driverside tire. Bad bearing. So I replaced it and the fluids.
Still made the noise and was told its just "tire noise"
Took tire off and saw fluid, so was told my axel seal was blown.
Why is this...
I noticed a knocking sound coming from under the hood. My father looked at it and said he is unsure he will have to look at it when he has more time. It knocks when I start the car up and once I begin to drive it stops. Soon as I begin to slow down the sound comes back. If you have any ideas...
