So I tried removing my front drive shaft this afternoon and failed! I could get the bolts out about a .25" and then they just didn't want to go any farther. Who has unbolted theirs and did you have this problem. I really didn't want to force them and snap one.
Did a starter on my dads 2005 grand cherokee over the summer. Lube them up a bit and back them out. You cant get the driveshaft out after its all un bolted. You have to support the transmission and drop the crossmember in order to have room to remove the driveshaft. Very stupid design.
I had to unbolt the drive shaft on mine when I replaced the starter and it was a ***** to say the least. The bolts on mine had loctite on them. I had to switch back to the breaker bar repeatedly to get them all of the way out. Several times it seemed like they werent going to come out, but the good ole breaker worked every time.

If you look at the threads on the bottom bolt on the pic you can see the thread kicker in the threads. PB blast won't help removing these bolts. Breaker bar or impact gun with the right combo of extensions is the only way. This was one of the harder tasks for me when doing my pinion bushing.

Thanks guys! I had them all soaking in PB Blaster before starting and then I using a breaker bar, that was as far as they wanted to come out. I was not sure if this was normal so I stopped and snapped the pic. Now that I know I will get the impact wrench on it next time. The bolt for the pinion bushing look like it will be fun too!
Look into a Matco MCL18IWVS cordless impact wrench for those without a air compressor. That thing is on my Christmas list this year.
for that price ($615 on Matco's website), you could get a decent compressor and pneumatic impact wrench. then you'd at least have a compressor if you needed it for other air tools (air hammer, ratchet, grinder, nail guns, etc.).
i run the ridgid compressor below with a craftsman professional impact wrench.
Not bad but in some situations you wouldn't want that out on the trails with you, I have an OBA system by Viair which has about the same power on a 2.5 gallon tank and runs at 150psi. It isn't enough to power the air thirsty impact wrenches and some of those drivers don't even carry the power that the MATCO offers.
I will be doing this on Saturday, breaker bar in hand. I have no power tools.
I have to get that pinion bushing done. I plan to leave the shaft in place but unbolted. I also need to do the differential solenoids and fluid while I am in there. I expect that you will want to use more thread locker when reinstalling. That reminds me. I will need to pick some up before Saturday.
On the design of the shaft, I bet that the pain for removal was intentional. You would hate to have the front mounting break free and have the shaft pole vault your ride on the freeway. This way, if it fails, then it just drops and sits.
