Hi all.....I am new here to the forums.

I have a 2002 7.3 CC 4x4. I noticed the other day when turning sharply and getting on it a little to cross in front of traffic I was getting a thumping feeling from the rear end I think. I am not sure if I have limited slip or not but it almost felt like it was grabbing as I turned. Any ideas what it could be?

thanks,
Tracy

 

Welcome to FTE Tracy.....

Have you ever changed your rear diff oil ?

May just need to replace your oil and add some modifier.

Here is a link showing you how - Welcome to guzzle's Rear Differential Maintenance Web Page

 

agree with Mevans
get the Purple Red dif fluid, it has friction modifier in it.

and see what happens.

and welcome to FTE.
