That doesn't sound like the typical failure as I understand it, and I kinda doubt it could be covered under the subframe campaign. My '81 380SL had the old style subframe and a couple of the A-arm tabs were cracking when I bought it. I had had them welded, but when I went to the dealer for another matter and brought the repair to their attention, they had the MBUSA regional service rep come out to take a look. The rep had the subframe replaced by the dealer. I paid only for new subframe mounts and engine mounts. They did the R&R and alignment. The difference between the old and new style subframes is that the new ones have the tabs that hold the A-arms reinforced with a kind of a box section on either side of the tab. My guess is that, even if you had cracking in the new style in a place that could cause suspension failure, they may possibly replace the subframe, as there is a history of subframe cracking and failures. The liability, should one fail and cause someone to get hurt, may really be the deciding issue. The mention of that fact may tip the scales if the rep appears to be declining the repair. In any case, It's entirely up to the MBUSA field service rep. I'd also assume that if you have a really good relationship with your dealer it could go a long way towards getting MBUSA support. The original purchaser, at the dealership where it was purchased, always has the best bargaining position, especially if they see you come in on a regular basis. But again, since in your case it is the chassis rather than the subframe, they will likely decline to perform that repair as a warranty repair. Now, if they do, please let me know as I have just discovered a small crack starting in one of my chassis engine mount support horns on my SD. ;^)

At first, he said he would weld it (He had at least 2 nice welders in his shop), but then he said he would have MB do it. I am guessing he thought about the liability if the weld failed. Not knowing about any other failure, and only going by what he showed me, the crack was in the mount for the subframe, and not the subframe itself. Not sure if this is what the normal failure is. It definitely can't not be fixed without welding the old one, or cutting it out and putting a new one it. Dave W
