Thanks for this Thread, this last week, noticed vibration under load with full jake, loud clunk when I throttle out of Jake. Also a load noise(sounds like air rush to clunk) when downshifting on hill quickly, if I throttle down a little and then shift no noise... Half Jake no symptoms. Trying get home, be ok if I drive no exhaust brake? I just bought this truck with 461k and have put $15k into parts and repairs so far...this exhaust problem is a 8 hr fix?
