    Help! Rear subframe bolts stripped to the frame

    I have 3 more bolts left to drop my rear subframe. I was feeling good, almost there then bam they 3 of the 4 bolts are stripped just enough to slip. I stopped so I didnt make it any worse, but I am stuck here.

    Options?

    drill them out. Once the plate is off, you can remove what's left with some vise grips.

    Digging all the schutz out of those hex holes usually seems to help them not strip.

      other options - angle grind the heads off, hammer a torx into 'em

      those bolts suck and commonly get frozen in place

        Thanks, the first one came out so easy, the next three I knew they were bad the second I tried to turn it.

          You can probably get a bolt extractor around them or drill them out.

            yeah all options listed should work.

            1) Take angle grinder to the head.
            2) Pound on bolt extractor socket.
            3) Drill it out.

              Just bought some bolt extractor sockets, lets see if those work.

                  Got them out. One came out normally. One I was able to get out with a bolt extractor. One I was able to break off the head with the bolt extractor and knock it out. Last one I had to drill all the way through.

                  At least its done and the subframe is out.
