no it does not
It's either the control arm bushings or the rubber mounts for the shocks.
quite possibly the A/C compressor clutch. The whining should decrease when the A/C is turned off. You will still hear some of the noise due to the clutch turning while the engine is on.
Check for spark plug blown out. Cylinder head repair may be needed as well as replacement of coil and fuel rail. This will cost a few dollars.
Usually when a wheel bearing goes bad, it will begin to make a high pitch noise like a bad humming sound and the sound increases as the speed of the vehicle increases. Take it to a shop and find out if they will check it for you.
Check the belt on the ac compressor of the 2004 Navigator. It sounds like the belt is slipping when the ac first comes on.
Typical U-Joint noise. Makes noise in reverse but not in drive. Check both front and rear U-joints of the drive shaft. If one is bad replace both. You do not want to go through R&R of the drive shaft twice.
I every instance that I have experienced this same "clicking" noise that you describe, it has been a "CV joint" or constant velosity joint which is at the drive axle pivot point at your right front wheel. If I am correct, this noise you are hearing points to a replacement of the joint. In the future you might (when on a hoist) check both of the rubber "boots" on both axles that house these joints by inspecting them for wear, this joint is heavily greased and protected by this rubber boot and should not be ripped or torn. If the rubber is damaged it will not be long before the absence of grease, including the effects of sand and dirt completely destroy a CV joint. I agree with the answer above, however, will add that I recently had new tires put on my 04 Navigator and "suddenly" developed a clicking noise from the drivers side front tire. It turned out to be my brake dust cover that was BENT at the tire shop. I removed it and the sound is gone. If you have dust covers on check that as well.
State your noise.
You should be able to hear the compressor Overtime the compressor will get noticeably louder. This doesn't necessarily mean that it's failing or should you be alarmed. If you are concerned I would suggest that you take it in and get it checked out.
yes
i hear a noise every time i turn the rear ac
