So I was able to remove 1 bolt so far. I didnt want to start rounding off bolt heads.
Soaking with PB blaster. Anyone with experience removing these bolts undamaged would be helpful.
I am looking to drop drive shaft to pull engine and trans. this is the last connection, except motor mounts of course.
Thanks

They should just come right out. Make sure you use the right sized 6 point wrench. Sockets are hard to get on and a 12-point socket can round them off.

Apply heat to the yoke where the bolt threads in. Sometimes heat then cool and then heat again works best. While the yoke is hot, remove the bolt.

Smack the head of the bolts a couple of times with a hammer and punch not hard enough to mushroom the head but hard enough to jar the bolt also try tightening just a hair then loosening.

damn who knew it would be hard to find a 6point socket....everything is 12 point.

You need more tools!

When you do get those out, be good to yourself and replace them.

Oh they are getting replaced for sure.

Yup heat the yoke not the bolt.
Hot as you can get it with mapp gas and if that doesn’t work, Acytlene torch.
