Long story short, 2 of the 3 bolts holding the left rear trailing arm broke on me. One broke and left some of the bolt out of the hole so I thought I could get it with heat and vise grip but nope. She is stuck. The other one broke and what is left is in the hole.

I cannot believe I am the first 914 owner dealing with this.

As I said, for the bolt that left me something to work with my plan was to heat it and use vise grip to try to get it. Tried on multiple occasion but she does not want to come out.

For the other one I guess I only have left to dril it out and try to redo the threads hoping for the best.

Does anyone has any other advice or method to try.

I do not have a welding machine so welding a nut is not an option for now and not sure it would work (for the one that sticks out of the hole).

I am open for any advice. I plan to work on this with my son this weekend.

Thanks

I had the same thing happen to every one of my studs. Didn't know that much about the way the bolts were held in and snapped every bolt.

I drilled out every bolt with a small drill, then larger and larger until I could slide a bolt all the way through.

Temporarily I put a bolt through with a nut and washers through all

Then added my own nuts welding 2 in series then welding to the mount.
