Help snapped rear body mount bolt Mu

Postby tonkamu » Thu Aug 16, 2018 8:39 pm

Will put some pictures up but I managed to snap a high tensile bolt trying to get it out for my body lift. The mount is the smaller rear one near the fuel hose, I think its the only mount you can't reach the top of?

I can still move the body from the chassis, It sticks out half an inch and rubs on the lower mount while driving. I haven't tried to get it out yet still scratching my head and so have the mechanics I've briefly asked.

Anyone have an ideas how to get it out?

Did you get the bolt out? I would like to do a little body lift on my Mu but don't want to get it certified. I wonder if the WOF boys will notice 10mm packers of rusty old steel slid under the mounts? I have pushed up the autotrans and transfer case hard up into the floor tunnel and could do with a an extra 10mm of clearance now.

They probably wont notice 10mm spacers unless it looked obvious.

Nah I haven't had a go at that bolt, not sure how to get the broken bolt out.

Quite often when you start drilling with the smaller drills and opening the hole out the rusted bolt will start to move. Only the really bad ones don't loosen up and they need to be tapped out the best you can. Guess its also in a place you can't get any heat (gas torch) onto being near the fuel tank. Good luck.

that's all good in theory if I could reach that broken bit of bolt which starts about 4 or 5 inches above the bottom body mount up a small hole. id need a drill bit over 6 inches long small enough to start a small hole with out sliding off and it would have to be made out of some sort of really hard alien metal.

Was I reading correctly that there is a stub about an inch long? No promises but this might work. (better odds than winning lotto on consecutive weeks) Tonight spray your favorite penetrating oil on it generously. Tomorrow night do it again. Repeat for 12 evenings. Then following morning while your kids are opening their presents get your mole grips and if you have been good this year Santa might let you unwind your present.
