Dana 60 HELP!!!!
Hello,
I recently purchased a 68 roadrunner pro street set-up with coil over rear, ladder bar suspension. narrowed dana 60 spooled with 4:30 gears. It goes very well under power then when I left of the throttle you hear a chatter/marble sound coming from the rearend. I have had the rearend apart 3 times with very good dana people and they are all puzzled. The gears, bearings, lash, wear all look excellent. I have even changed both pinion bearings and made no difference. I am looking and all items to check. It just does not seem it's the rearend but very puzzled. Thanks!!!
