The first thing to check for a wobbly rear end noise is the wheel bearings. If they are ok, check the brake system for worn or broken parts.
I hear a clicking noise coming from my jeep when I hit speeds greater then 50 MPH? any ideas on what can cause this
sounds like bearings in the differntial
leaking or cracked manifold
Its hard to say... do u know where the noise is coming from?
The most likely cause of the whistling noise is loose or worn weather stripping around the door. If this is the case, the sound heard is the wind.
