I'm having issues with my speedo in my 96 Bronco. The needle starts to jump around when I reach 40 mph and greater. I replaced the speed sensor in the rear end and continued to have the same problem. I pulled the speed sensor to check the tone ring in the rear end and noticed that just one tooth on the tone ring had the top of it missing (not sure how that could have happened). Could this be the cause of my problem and if so how hard is it to replace the tone ring in the rear end. Any help would be greatly appreciated. Thanks in advance, Chris.

"...1- Remove carrier cross pin bolt, and then the pin.
2- Push in each axle to expose the c-clip, then remove the c-clip and pull the axle out of the carrier.
3- Mark the orientation of the bearing caps... The bearing caps are marked for direction when they're cast. Remove bearing caps.
4- Pull out the carrier, taking extreme caution to not mix up the bearing races and shim packs. They must go back in exactly as they are in right now, or you'll have to do a full gear set up when you put it back in.
5- Don't remove anything from the carrier that doesn't fall off.
6- Find the internal locating tooth on the tone ring, then spin the carrier 180
