MarkB only comes on here to stir things up, he's not a builder or a problem solver. he snipes from the sidelines at other peoples builds and in my opinion has nothing useful to contribute.
He seems to have failed to understand the problem Nathan had with the diff failure and has tried to use that as a way to attack the basic chassis design which has already been proven. (Are the Sierra based chassis's failing - NO)
He tried to use an example to highlight his point but the builders of that car are having EXACTLY the same diff problems!
His argument is as flawed as his engineering knowledge. Waster
Sorry AshG - I accept a wrap over the knuckles for such strong statements but we don't need this guy poisoning the forum.
