You probably are having pinion bearing problems. It seems that ford had some rearend problems with some of there trucks and suv's.

Ford explorer making thumping noise from rear driver side only when turning left has been doing this for two years not all of the time I have been to 8 different shops and no one can figure it out

Has anyone checked the rear driver side axle shaft when it is making noise? The length of the shaft can be shimmed on some applications. When the vehicle turns left, this axle is on the inside and it is pushing into the differential. The position of the axle bearing usually limits travel of the axle shaft. Whether or not the axle bearing is properly mounted on the shaft or if the axle housing is worn and allowing the shaft to travel is a possible issue. But it is worthy to note that the brake components can make noise when rust is being knocked off from parts shifting from where they normally ride. The extra play could make rust ridges hit and make noise.

That is why I asked about someone jacking the rear wheel up and noting if parts are binding.

Whine in overdrive 5R55S

Update: Differential shop says all components appear to be in good condition, ring and pinion pattern good, no metal in fluid. Slight noise audible, apparently not differential in origin.

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.

Msn.comi have a 2002 ford explorer xlt that was making a whining sound in the rear end and now does not drive at all. Looking thru some web sites on this problem i have noticed that this has been a...

there was no recall for this and the only solution is to replace the differential or if there is no housing damage then replace the interior components(gears,bearings,races,shims,etc)if there was a whining noise then you should have done something about it before this happened and let get to this all receipts and make sure the shop documents everything and you get a copy in case ford is pressured through the court system to repay customers with this problem at a latter date(class action law suit).

Whine from rear differential when accelerating. the whine stops when I take my foot off the gas pedal.

when was the last time this was a replacement differential oil with additive MIGHT quieten this down.........however, this might be unlikely if the vehicle was not regularly serviced......if it only occurs whilst acceleratin this indicates wear on the main wheel/pinion......this COULD be an expensive repair....

I just started having problems today. 2001 ford f150 . It felt like tranny was slipping. Checked fluid, a little low, topped it off. truck goes into reverse but wont move backwards. truck moves forward...

Sounds like the rear end differential is going out. I had a similar problem on a customer's truck, and it was the differential in the rearend. Replaced the rearend, and the noise was gone.

I replaced the 2.73 gears with 3.42's and it makes a whining sound, and a knocking noise. I've checked the backlash and tried putting shims in, but it still makes the sounds.

why not go to the local salvage yard and buy a whole rearend with same gears as original or new gears but remember to change the drive gear on the end of the speedo cable or you will have the wrong speed

Rearend noise on 2004 Ford Explorer Sport trac

what type of noise?
have you checked the fluid?

if its a grinding noise while driving it could be choppy tires carrier bearings or axle bearings.

if its a whine while accelerating or decelerating than it is pinion angle.

if you can safly get both rear tires off of the ground than start it and put it in gear, try to locate the exact location "center chunk or out far in axle tubes" make sure vehicle is secure and safe befor climbing underneath.
