Driveshaft bolt removal

97 4.2 manual. Trying to get driveshaft off to drop tranny. The bolts are really stuck. Not particularly rusted, but putting PB Blaster on them nonetheless. Have tried long-handled half-inch ratchet to the point I am afraid I will twist one off.

These things are not reverse threaded for some reason are they?

Anybody else had the same problem and come up with a trick to break them loose?

All I have are normal hand tools, so no air impacts or acetylene torches...

Thanks!

Try a 12 point closed end wrench with a cheater bar.BTW,don't forget to mark the driveshaft flange with the differential flange before removing it.

Thanks BlueOval,

I got a hold of a 3/8 flex handle that allowed me to put wrench to socket right on the bolt with out any swivels and such and made myself a cheater pipe that I could manage under there. Heated them with a propane torch and finally managed to get two of them lose so far -- started raining today so have not tried the other two. Had not had a chance to get back on here until now.

Those bolts have a 70-95 ft-lb torque spec and are very stiff... Would you recommend replacing them when I put back on? Not sure if the amount of heat I applied would be enough to change the temper or not -- just a Burnz-o-matic thing.

Does not matter how it goes back into the tranny does it? Just want to match up the bolted end to its original position, right?

Thanks..
