Tonight I decided to change the diff fluids with my oil change. The front i knew had been changed since I bought the truck. But the rear to my knowledge has never been touched and when i drained the fluid it was quite apparent. Now the bad part is when I took the rear cover all the way off, sitting on that little magnetic tray inside the pumpkin, was a huge piece of metal and metal shavings all over the place.
I researched the part that i found a little bit and what it is, is one of the limited slip clutch retainers had come out of its place and now rest at the bottom of the diff. And i found part of a second retainer that may be coming out soon. The rear end doesn't make any noise and drives just fine. So i pulled the parts out and filled it back up with fluid. This is my only truck right now so i don't have a real option of parking it again like i did when the trans went out.
But from the looks of it, I have to plan on swapping in my 3/4 ton axles a lot sooner than i had originally planned.
