I own a 2001 Dodge Ram 2500 with Dana 60 front and rear. After driving any real distance when I turn left or right in forward or reverse, there is a clunking noise from the rear differential. Just curious if anyone else has had this issue. Friend suggested limited slip fluid to replace my current fluid. Thoughts or comments appreciated.
I would check your u-joints first. And just replacing your gear oil with limited slip fluid isn't going to do anything. You limited slip isn't going to cause a clunk. If your u-joints on your rear driveline are good then you need to make sure that the noise is really coming from the axle. You could have a clunk from the suspension, brakes, shocks or it could be something inside your rear diff.
Agreed with WMan on what to check. I'll disagree only slightly about sounds from the diff housing itself though, but that is based on the OP calling it a "clunk". Is it dull, low sound clunk, or higher pitch click? lol B/c the higher pitch click is a sign of the clips being broke...like here: https://dodgeforum.com/forum/2nd-gen...-rear-end.html
I had a similar problem, check the axle tube since the weld might of broken which causes the axle to slightly twist every time you go from drive to reverse or a slight turn.
I found out the hard way, which was to late to re-weld and broke my spider gears.
