I had the same problem as described here ... quoted "sometimes flashing quickly, slowly, or sometimes turning off. The antilock brake light has also come on several times."

and the dealership told me that the electrical conector that goes externally to the gear drive is getting dirty with oil .... two times I sent the car and they told me the same and solved it ... no charges at least but I having the same problem again ... I really want to know where is that electrical conector just to clean it up or put something that avoid dirty or oil get in it again ...

Possible, but any noise should be investigated fully. Start by checking front diff oil, then transfer case oil. Best to just drain both then look for any metal in oil.

Noisy rear diff or bearing any advice?


Needs to be off the ground to see for sure. When it comes to differential bearings I replace all them, to include the axle bearings. Depends on the vehicle. No year make or model. the differential also needs looked at.

My mechanic has found the transmission in my 2007 Toyota corolla ascent seca Hatch(automatic) to be noisy in first gear and also to be noisy when in top gear cruising at 60-70kms. There is a whining n


planetary gears are normally straight cut spur gears and will be noisy in operation. There may be wear in the shafts that they run on and there may be needle bearing wear. Normally you will not hear the noise as you are inside the car. The whine is an indication of a mechanical problem and will be there in all gears . There is a possibility that the noise is from the diff but if you listen carefully when driving if it is there under load but changes on over run(coasting) then it will be the diff of is on and off when you hold a steady speed it will be the diff. Have an accredited transmission specialist shop give you another opinion but if it is the transmission I would not race out right away to have it replaced.

Why is the rear end making a whining noise


The whining noise could be for many reasons. Narrowing the possibilities depends on when the noise occurs. If it happens only while decelerating at any or all speeds is most likely caused by bad pinion bearings or loose pinion bearing preload. If it happens during acceleration over a small or large speed range is usually caused by worn ring and pinion gears.

One cheap thing to check is the fluid level in the differential. If low, topping off the lube may help for a while.

Disconnected rear differential


You must have a 4 Wheel-drive. You should have a driveshaft for that end of the vehicle and you should not let the Mechanic keep it. The rear unit must have a bad Pinion bearing or more damaged parts. Some of parts can "freewheel" without having power going through them.

But the metal shavings from broken parts can travel inside the differential and cause more problems. You don't always need the 4-wheel drive function and you do not have it since the Mechanic disconnected it.

Sometimes it can be what is called an "axle" bearing. Each side has this part so you have 2. The noise levels for this part can also change when the 4 wheel drive is engaged.

Make sure the rear differential has lube. Read the Web for articles about your vehicle. Search "2003 Ford Escape rear differential".

There is a Salvage yard site called Car-parts.com which is good for locating used parts like differentials. One would need to match the same gear ratio as the front.

The diff has a wine and i would like to know if there is some adjustment


There is a shim adjustment on the yoke, but this is not usually the whining noise. Check the oil. Remove the plug and the oil should just come out of it. If it doesn't add some 80w90 weight till it does. Ford makes a pretty rugid differential. I have heard these screaming and still last for years. Built ford tough. Just remember to keep check on the oil.

Whining noise during accelleration on my 2004 volkswagon jetta. Brought to VW dealer and said differentail needs to be replaced at cost of 4k?


Get a second opinion or a third opinion. VW's are a common car and there are lots of Foreign car mechanics in Independent shops. Car-Parts.com is one of many Salvage sites for used parts if the Dealer is right.

Do a Web search for Salvage yards, then check with an Independent shop for what you car really needs. The Pinion gear bearing usually makes a noise only under a load. When you back off on the gas, the noise goes away. It is a matter of inspection for wear after the Trans is open.

If this is a Stick-shift, check your Trans lube. You might want to try a product called "Duralube". It has formulas for both Automatics and Stickshifts. Your differential may be dry too. If you can avoid opening the Differential you will save big bucks. You may need a few specialized tools for this job so it limits what you can do yourself.

If the Duralube does not help, discuss using Salvage parts with the mechanic doing the job. Just tell him that your car is 7 years old and you do not have that much money to put into it. He may have his parts sources. Sometimes the Salvage yards will give 1 year exchange warranties, sometimes a lot less. With a 1 year warranty, thats about as good as it gets used or new.

Seems to be a winding noise from the rear at higher speeds


You mean whining noise. You could have a worn differential or the differential is low on lubricant. Another possibility is a a worn wheel bearing.

I have a 1993 Volvo I purchased new almost 17


Could be tire noise, could be rear wheel bearing, differential (if rear wheel driven), or could be something associated with the brake.

Try swapping the tire with another tire. If the noise moves with the tire, it's the tire. If it stays, it's brakes (unlikely for the noise you mention), rear wheel bearing, or rear differential (lack of oil). Will probably need to have a mechanic to identify and repair.

Whining/grinding noise at deceleration


We have the same problem at our shop. We haven't rebuilt the front differential yet. We tried 3 different shafts on 2 different Jeeps and the noise is on both just the same. By greasing the front driveshaft cv joint, we got he noise to quiet some, but it is still way to loud. With the driveshaft out, the noise is gone. We are about to buy a new shaft from the dealer for $600. There are some service bulletins about some noisy driveshafts.
