I've got an 06 2wd access cab. I'm getting an intermittment clank sound - almost sounds like metal on metal - when I let off the gas after accelerating (never from a constant speed). It appears to happen most when the engine is cold but I have gotten it a couple of times when it was warmed up. I looked at the TSB for the exhaust ticking sound but that doesn't appear to be it because it only happens once as opposed to a tick-tick-tick sound. I did have the exhaust manifolds replaced for the sulfur smell. Could that sound occur if the didn't get the torque right and the manifolds are slightly loose?
The sound appears to be coming from the rear of the engine compartment but it is not always from the same place. I haven't approached a the dealer yet. It's so intermittent it may not happen for a month and then it will happen several time and the stop again. Any advice on what to look for would be appreciated. I'm stumped
