When this truck was put together someone did not weld this joint very good and could cause it to drop off to the ground.I a talking about the exhaust manifold pipe where the exhaust is hooked to. I had to have a catalytic converter replaced the one under the cab but I discovered thee is another one close to the exhaust manifold The weld is on top of the first catalytic conv. Bad weld and a short in the wiring in on door that the service manager taped up and said fixed and the fan motor switch in 8 years not bad?????
