2003 clunking from rear
Hey guys, first off thank you for any input anyone has on this im at a loss. Ive got a 2003 supercrew with 145,000 miles on her. When ever i turn and go over even the slightest incline i hear this huge popping clunkety noise coming from the rear. U joints replaced last summer so i ruled that out, plenty of fluid in the differential. I jumped up and down in the bed to see if i could recreate to no avail. It seems like it only happens when the truck is twisted. Any help is greatly appreciated! THANKS!

You might want to add some "Friction Fluid Modifier" to the gear oil. Under a twist or turn the clutches in the limited slip rearend may be sticking and they will pop or clunk when the break free. Very common issue.

My 05 is doing the same thing. When I'm driving around on back roads with slight inclines. It doesn't do it all the time though. I had my transmission serviced and replaced differential fluid. And it still does it.
