1999 C230k sport wishbone damage
Hi, I hit a traffic cone 60ish mph in the slow lane of the M6, the left front wheel tucked under and skidded to a halt. On checking the damage, I found very light panel damage to the front left wing and wing mirror broken off. However I was surprised to see the wheel become dis-attached from the lower wishbone at the narrow end just in front of where the anti-roll bar attaches and bottom ball joint. The metal looks extremely weak and corroded around the circumference slightly larger than a golf ball, I’m getting the impression that this is a weak point, either through poor design or corrosion. Can you tell me whether all of the lower wishbones are the same on C class 96 to 2001 ( have a 1996 wishbone available to me) Or does the sports model have the different,or stronger wishbone? No other parts appear to be damaged, apart from possible slight bend on the steering track rod end. Any comments or thoughts on repair would be much appreciated.
