Well... after working thru most ( not all ) of my basic driveability issues (still doesn't always wanna idle ) I've got one that really worries me. My rig has a terrible "shudder" if I attempt to give it too much juice on a hilll or even slight incline ( especially noticable if turning at the same time) on the street. Does this sound like a driveline ( transmission / t-case ) or rear end issue. It's stock 10 bolts with 3.08. Which ( and how ) do I test without breaking further? Thanks in advance!
