ticking sound from a wheel is usually a dry or worm wheel or axle bearing
The wheel bearing
When you drive over a clicking bettle.
Sounds like a bad drive shaft/CV joint
your Imagination.... :)
The wheel bearing?
Apparently it is the rear air "blender" ( whatever that is(?)) My 2003 Explorer was making the loud clicking sound from the rear driver side above the rear left wheel. I lived with it for a month before I just found the answer on the net. I turned off the rear fan control (from the front controls) and the clicking has stopped. I guess there is no more air from the rear now but the clicking has stopped- Car is long been paid off and I'm happy again.
there could be excessive clearance in the rear differential case if this is a rear wheel drive vehicle.
rear differential got lube? rear wheel bearings?
Bad tire, wheel bearing, bent wheel???
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.
the most probable cause of clicking on rear brakes are weak return springs or a broken one.
This is more than likely a rear wheel bearing/hub. Is the noise related to road speed? If the noise gets louder with increased road speed, then the problem is almost always a wheel bearing/wheel hub. Terry Naber Naber Automotive Inc
My 2003 cts has "differentail noise"not wheel noise. I hear its somewhat common. Unfortunately rear end failure is somewhat common. I have had the same noise for years, and I am at 130,000 mi. No failure The answer to your question is that when the transmission stays in the lower gear due to not having got your speed up, the noise will happen... it`s not due to a mechanical problem.
it sounds like your wheel bearing if its a whaling noise
Frequently the scrapping noise indicates that the brakes need repairing.
As with any bearing going bad it would growl and the noise would increase with speed.
it might be your drive shaft or transmission going out.
without more information i would say it sounds like the wheel bearing.
If it happens only when turning corners, this is likely to come from the differential. A ball bearing problem would make noise all the time.
it could be a bad wheel bearing.
u might want to check your rear cv-axles also rear wheel bearings , sometimes when bearings are worn it may takes a little load to start a rubbing, scrapping ,grinding noises or something similar if the axle may be bad also it may take a little load to start a little poping noise or similar to a little clicking noise excetera... note: if is a 2 wheel drive then u wont have rear cv-axles
If the clicking noise you are hearing from the rear panel in your Mountaineer is coming from the passengers side, you could be hearing the relay contact opening or closing for the automatic headlights (if equipped), rear window defrost, rear wiper, or a host of other features. Behind the trim panel in the rear passengers side are a bunch of the control modules, including Security and Body Control.
Probably a damaged gear or bearing.
