"thunk" on right turns

Recommended Posts

My 97 SE has an lsd that as far as i know is acting like an open diff...likely the plates are worn? Anyway...i often notice a pretty good thunk coming from i believe the rear end on right turns. I feel i once knew what would cause this...but memory goes when getting old. Anyone know what causes this?

Only thing in the suspension i've NOT replaced in last three years are springs and my OME medium loads arrive today. Otherwise ..all links have 4x4parts poly bushings as does panhard rod. Sway links are a few yrs old as are sway bar bushings. It is a "only on 90 degree right turns around city street corners" phenomenon.

 

IIRC..i thought this happens with like a locked diff...?

You are certainly suggesting the characteristics of a locked differential. Have you checked your pumpkin for signs of leakage? Checked the oil level?

Put in Mobil 1 a few yrs back...and lsd additive. Haven't checked level in a while..will look for leakage tonight. But this past winter backing out my driveway which is uphill to get out...driver side didnt spin at all while drive tire was spinning like crazy. Is it even possible for an lsd to lock up? Can the plates fuse or something? Iirc what i'm observing is called wheel hop?

 

Maybe it's my pathy's way of telling me it wants me to put in an ARB air locker? :-)
