    Broken Subframe.

    Well, it appears that the car I just bought has a broken subframe rather than a broken motor mount. Not that I really car either way. Can I weld this subframe back into place? Where the rear passenger mount attaches the cradle has come off. A welder should be able to hold that up, right?

    Broken Subframe.

    Same thing happened to my friend's Regal. He got one with the rack and pinion on it from a j/y for $100... it's not to terribly hard to do but it's still pretty hard to do. Welding may be the way to go if you have the tools and such.

    Broken Subframe.

    Hmm...with some of the problems Ive been hearing about,I would feel safer getting a complete Good Used frame cradle from the salvage yard then trying to fix the old one.I have no doubt a good welder can fix it but theres no guarantee the fatigue of the metal isnt still gonna be there someplace.

    Maybe get a used cradle and have a welder reinforce stronger plates onto it in places for extra strength?

    Btw is your cradle rusted a bit?Do you know what the main cause of the breakage may be?Those are important questions to ask before repairing old cradles.Just trying to offer some additional insights to the problem.

    might help if you post pictures, but depending it ought to be just fine if its welded back together, if the welder is somewhat compitent.

    it just broke at the original weld. The previous owner hit a decent pothole and it fell. The subframe isn't terribly rusted. Looks to be in decent shape.

    just get it re welded, its not going to weaken it, if its welded good it will be just as good if not better then OE

    Do you mean that one of the cradle mounts broke? Welding it back up woudn't be a good idea in that case, because the subframe needs to be dropped to do quite a few repairs.

    it's all welded up. Holding like a champ. Much easier and cheaper than a new subframe.
