A Very Challenging Problem
THIS PROBLEM HAS STUMPED TWO INDEPENDENT MECHANICS AND 1 FORD MECHANIC AND ME. I HAVE A 95 E-350 AND IT SOUNDS AND FEELS JUST LIKE THE REAR BREAKS ARE TOO TIGHT.
THE HOTTER IT GETS THE WORSE THE PROBLEM. WE ADJUSTED THE BREAKS UNTIL THEY WERE NON FUNCTIONING AND STILL THE PROBLEM EXISTS. WE HAVE HAD THE BRAKES REPLACED ANYWAY, BUT NO HELP. THE PROBLEM DISAPPEARS IF YOU PUT THE REAR ON JACK STANDS, SO WE HAD THE HUB BEARINGS REPLACED ALONG WITH THE RACES AND U-JOINTS. THE REAREND HAS BEEN OPENED AND INSPECTED, BUT NO PROBLEMS FOUND. THE MECHANICS HAVE GIVEN UP AND I AM ABOUT TO.
H E L P !!!
I WOULD GREATLY APPRECIATE ANY HELP ANYONE CAN GIVE ME.

ron from texas...
your suggestion about the limited slip clutches grabing sounds logical. however; the problem exist at low speeds ( 3-5 mph. ) and in reverse. do you still feel this could be a possible source of our problem? if so how would one repair the clutches or should they be replaced?
We dont carry heavy loads, the drums dont overheat, and the drums pull off easily even when hot.

ps...thanks everyone for your replies

I have to agree that it's the rear differential, but putting it on jack stands puts no load on it whatsover. All that would be really good would be for checking binding breaks or wheel bearings.
Is not the brakes, you said they came off easily, and if they'd been binding they would have burned your fingers!
When you stomp on the brakes, do the backs lock up uniformally if at all?
Been my experience with these vans that the rear brakes don't do much & the fronts take the brunt of stopping.
Something else is binding, be it the diff itself, or else perhaps the axle is warped? Not at easy task for you I'm afraid, but good luck!

Your brake pedal might not be returning all the way back up. Put some spring on the brake pedal so it will pull up once the brake pedal is released.

Limited slip noise
The limited slip can make noise at low speeds and while backing up. The noise does get worse when the diff is hot. The limited slip will ONLY make noise when the vehicle is turning. The tighter the turn, the more it happens. In a straight line, the wheels are turning at exactly the same speed, so there is no differential speed between the wheels and the differential portion of the rear end turns as a unit. The limited slip is not active in a straight line.
My '69 Ranchero would repeatedly "clunk" and the back end of the vehicle would jump about 1" sideways when I backed into a parking place with everything hot. It was still doing that @ 130,000 miles when I sold the truck.
