Does anyone have access to TSB's? My truck makes a clunk/bump in the drivetrain that i can hear and feel when i stop and sometimes when i accelerate. i saw that there is a TSB on edmunds.com about a problem like that and i was wondering if someone who has access to the full technical service bulletin would mind posting it in a reply? I think it's bulletin #68 or possibly #75 on the list that i saw. Thank you so much.
