Snapped a transmission mount bolt on T-Case skid plate

While installing a transfer case drop I snapped one of the four transmission mounting bolts.

So ... now what?

Can it be driven like this?

How do I pull the broken bolt out and to replace it? The head cleanly snapped off.

Out of curiosity - and if you have a minute to read on, how critical was it to loosen these bolts when doing a TC drop? I bought a Skyjacker t-case drop kit (which I do not recommend) and their instructions don't mention loosening the four transmission bolts while dropping the t-case. The t-case drop written in 4x4xplor http://www.4x4xplor.com/t-casedrop.html states to loosen them first and then tighten them as a final step.

Who is right? After having it installed for about a week I went back into it tonight as strange thumping develop under my foot while driving - I could feel it hard when driving 30 or less over minor road bumps. Figured something had to be loose which is why I started checking everything tonight and snapped the bolt.

And while I'm on the topic of conflicting info ... Skyjacker says to torque their six skid plate bolts down to 75-80 ft lbs. Two of the six stripped before getting to this level. As they were around 55 to 60, I left them in until tonight. I pulled them and replaced them with grade 8 hex bolts and torqued them to 55 ft lb per 4x4xplor.com. Again, which is the right spec? 75 ft lbs or 55?

It is a good idea to loosen them before dropping the skid to lower the t-case. It will eliminate any stress on the transmission mount.

You should be ok with 3 bolts, but if you want to replace it, you are going to have to support the transmission and then drop your t-case skid plate to get to the mount.

Off the top of my head, 55-60 ft/lbs sounds about right for the t-case skid plate bolts.

The clunking you are experiencing is most likely your t-case linkage that is contorted since your t-case drop. To correct it, I suggest installing an Advance Adapters re-location bracket.

Thanks Rocky. Nice rig by the way.

Anyone else with an opinion on how critical this fourth bolt is and ways to replace it?
