Hey guys,
Doing a complete front end overhaul. Everything came apart fine except for the driver side upper wishbone pivot bolt. It's seriously stuck in the frame. Unfortunately even after soaking in PB Blaster overnight, I broke the head off of the bolt. Next I tried to pull the bolt out from the back by stacking washers and turning the lock nut onto the threads, thinking it might pull out the opposite way. I heated everything up with MAPP Pro first (probably not enough) and I cranked it down with a breaker bar until suddenly the nut jumped threads, making the end useless. I then thought I might be able to drill into the front side of the bolt where I can get a drill in, stepping up with bigger bits until it's mostly pulverized, but the only way to do that was to get the A-arm out of the way. No way to slide the wishbone off of the rear of the bolt where the threads are so I cut the bolt thread side off between the frame and the arm. Once the arm was out of the way, I tried to drill into the bolt but it's extremely hard and I ended up breaking a bit off inside the bolt.
Yeah, that kind of disaster.
So I have been heating up the ends of the bolt along with the tube that the bolt runs through with MAPP, and then holding a slightly smaller short bolt in vice grips while hitting that small bolt with a hammer so that I don't flatten the ends of the shank I'm trying to get out. No luck so far. I keep hitting it with PB Blaster in the meantime.
I need some ideas because this is getting bad.
