Thanks to you all I got the diff out today and sure enough its locked up. Boght a new one off a local rover guy for 150 and it should be her monday or so... Ill let you know how it goes. Thanks again. -Joe

Yes I am quite sure it is the rear diff now. I left one wheel down and lifted the other and i cant turn it for the life of me... isnt that suppose to turn the drive shaft prop? Oh and youre not going to believe this but i am finding it impossible to remove these little decorative caps over the nuts keeping my wheels on. I dont care if i have to break them off... any ideas?

quick update: I removed the drum parking brake and the rear axel and put the car in neutral with diff lock off and i cannot push the car... the rear wheels are still locking up... gonna look inside diff tomorrow. I will tryyour suggestions starting with the easiest tomorrow, but for youre amusement, only one drop of oil came out of the rear diff when i tried to drain it, which is a big clue that there is potential for a big problem. anyhow, im off to class, i really appreciate the help. Ill post again in the morning. -Joe

Thanks for all youre help. I will recheck the handbrake by simply removing it before i proceede further with the differential. Ill keep you all posted. I thought I had tried driving it with the drumbrake off completely, but i could be mistaken. Thanks again, Joe

I thought of the handbrake problem so I took it off completely and tried it to no avail. I also completely jacked up the rear of the car till both rear wheels did not touch ground I spun one, making the other spin in reverse as it should, but then i got under the car and tried to turn the prop (triangular thing pictured above) without the driveshaft on just to see if it would turn the wheels, and it was stuck. this all bipasses the handbrake and other gearboxes so it must be the differential. As for opening it up, i did not remove the halfshafts... I dont know how i would do that with only one jack in my driveway. Any suggestions? thanks, Joe

I have very limited knowledge but as you can see from the picture i have removed the driveshaft and removed all the nuts around the differential case. It still would not come off so i assume i have to remove the flange (trangular part at the front where the driveshaft connects). It will not pull off, and im not sure what to do. Also i dont know if i have to pull out the pin in front of it, and if so... how? Also, i meant that the gears inside the diff are seized.. or so i think but i ont know unless i can open it up. My rover drags his rear end if i try to drive him and its not the Transfer Case or the Transmission. More images are available here http://70.187.217.161:5222/rover/

Hi all, my 97 Disco broke and after much investigation on my driveway it turns out my rear differential has seized. I have a rear diff from a junkyard lined up but I cant get the cover plate off the one still on my car. I plan on replacing just the gears rather than the whole rear axle. I know i have to remove the flange but i cant do it... I assume you remove the pin with a special tool but i heard you could do it without the tool. I also heard you could just pull it off with some force but thats not working for me. Anyone know? Thanks, -Joe
