Hey guys my 85 with a GSL rear end sometimes makes a loud groaning noise when coming to a stop. The noise is not constant and is quiet as can be when driving. I just recently change the fluid as well but did not have any GM lsd additive on hand so I use KW positrac instead. Any thoughts?

Thanks, Ed

Anyone? I have searched but found nothing. One member had a similar problem back in 03 but posted no results.

Thanks, Ed

i've noticed this too... sorry, no idea...
