One of my cab supports has a broken leg.
Those of us that have spent a lot of time in the "engine room" of GMC know of the three legged support that goes from the cab floor to an isolator on the frame. I had never noticed any problem here, but when pulling the front frame yesterday, I have found a problem. At that time the assembly was rolling nicely, when I noticed something wrong. The A/C clutch had carried along an unrecognized piece of aluminum.
That piece was discovered to be one of the legs of the right side cab support. Quite specifically the one the leans into the engine space. It appears to be a part of the welded aluminum structure. It also shows a lot of wear on the surface that was supposed to be a part of the cab floor structure.
Plan to repair is undetermined at this time, but if anybody has any experience here, I would love to hear about it.
