    my machanic did put an additive in the differential.and he said the same thing. that the noise is common, and not a major problem. I thought maybe there could be something else going on inside the differential. ( the additive helped alittle ) Thank you.

2003 ford expedition leaking some type of fluid from what looks to be the differential and the while driving the floor vibrates as if somethings grinding together in the front.


Can be vibrating from loss of differential fluid. You have moving parts in the front, more so with 4x4 units, that need lubrication.

The driveshaft can also transmit vibrations.

You need to have a hands-on inspection of the underside of your vehicle.

My 99 Ford Expedition rear differential locks when I turn the steering wheel to the left or right, also as I am driving it makes a grinding noise and it locks as I am breaking and when I accelerate. Should...


This is bad, rear end locking up and grinding, i will bet the bearings are shot and so is the ring gear and pinion gear . the cost to rebuild this will be costly and you would need a tech to rebuild it . if the ring depth and pinion depth are not correct then noise will start and wear,

I thing the best bet is to locate a used rear end, and install it. it is not hard to install used differential .

When you remove the cover save tag that is on bolt to cover, you will need this when locating used rear end, also count teeth on ring gear and pinion then divide to get the ratio. there is a good website that will help you locate a used rear end in your area.

the site is http://www.car-part.com/ Hope this is helpful. good day

Corvette makes a distinctive 'clunk' when engaged in gear and starting to move forward or back. Chattering in left rear hub when making left hand turn. Rear suspension and all brake suspension...


The two symptoms you posted may or may not be related. I'd check the driveshaft and axle joints for any looseness or binding. (do this with the rear wheels hanging free in neutral, front wheels blocked)
The chattering may be an axle joint or the posi unit in the differential. Most times replacing the diff lube, (using posi additive) then making tight left and right circles will free the clutch packs.
Difficult to diagnose noises online. If you have any problems finding the source, have an experienced tech look at it,,,You still have the option of actually doing the work itself.

While in drive, hear clunking and grinding from front differential and axles chatter and hardly spin, drivers side chatters,passenger side spins, put in park, then back in drive and then passenger side...


It sounds like your limited slip differential is in need of a fluid change.
The clutch packs in the axle require a special friction modifier,about 4 ounces added to the axle lube,which fixes the chattering issue.
I'd suggest someone drop the axle diff cover and check or change the
fluid,to see if there are any big metal pcs. in there. If there is no damage,drain the diff fluid and add the friction modifier,only if a SLD..

Note: Only add the friction modifier,if you have a limited slip differential.
Since I can't physically see your vehicle,make sure a mechanic does
it right.

After my 2001 Eddie Bauer Expedition warms up...


well i have heard that the front hubs are known to go bad in the 4x4 pickups,which should be the same parts as an Expedition,there may be metal dust on the ABS sensor or the flywheel it reads off from,thats if the hub and or bearings are bad.Jack it up with a jack under the lower control arm just behind the wheel and grab the wheel at the top and bottom and see if there is any movement,that should help explain if the hub is bad if there is alot of movement

2001 Ford Expedition - starts, won't shift out of park, windows n


Check the #15 fuse in fusebox behind marked panel on left lower dash just below and left of steering column. This is only a 5 amp fuse but it controls a lot. This fixed our 2001 Expedition. 25 cents.

2004 Ford F-150, my rear differential seems to be chattering when I turn left or right from a stop. Do I need to replace clutch packs or just change differential fluid and add modifier?


start with a fluid change.its the cheapest. chk the fluid as it comes out for metal flakes. you may have sticky parts. drain , fill with diesel and turn tires by hand, let sit for half hour and turn the tires again.do this three or four times then drain and replace fluid and modifier.

Grind in Dana Differential


drain the fluid and refill with limited slip gear oil, add one bottle of friction modifier, ( this is very important) the noise is the clutches sticking.

1998 ford expedition 4x4 not working transfercase works


Today I fixed the vacuum lines to the front differential (nee transaxle). I had trouble finding parts in the local auto store that would do the trick - but I got something cobbled together. Based on my experience, I can go back to the store and get the right parts for a proper fit.

As of now, 4WD will engage but will not disengage - clearly one of the connections is still poor, or I accidentally switched the ports, or the vacuum shift motor (attached to the front differential) is shot (obviously from abuse).

As near as I can tell, once I switch into 4WD-HI, it will not shut off. 4WD-LO will engage and disengage properly. If I turn the car off for a while, a couple of times 4WD has disengaged. Hmmm...
