Need to remove the driveshaft from the wife's F150. Obviously I've removed the four bolts (and marked the position of the driveshaft). I read in another post before that he had to use a floor jack to pop it loose. So I tried that and started lifting the back tires off the ground. Driveshaft won't budge! Any help?! Thanks!

 

Use a large screwdriver or pry bar to get the drives shaft off the spot face and then slip the drive shaft out of the transmission or transfer case.

 

This was my second unsuccessful attempt at removing the driveshaft. After the first unsuccessful time, I went to the forums and read about using a floor jack to pop it loose. Tried that last night and still could not get it removed. Only had about a half an hour before I lost daylight, so not much time to mess with it. Sprayed it down with penetrating lubricant (did that the first time too) and went back to work on it this morning. Gave it a few whacks with a mallet (not on the driveshaft) and then took a pry bar to it. Finally came off! This isn't my first time removing a driveshaft (been a long time though) but never had such a difficult time.

 

You don't say but I'm assuming you're trying to take the drive shaft off the differential. I have not had to deal with this in years, but I did have one once that wouldn't come out. Friend showed me a trick that worked. Loosened the bolts on the straps that held the u-joint onto the pinion maybe a half turn each. Started the engine and put the tranny in gear and rocked it forward and backwards 3 or 4 times. Shut it down and checked, the U-Joint came out of the pinion without any issues and was able to remove the driveshaft without any further problems.

Good luck, hope it helps and be safe.

 

I did get it removed, and yes I was trying to get it off at the diff. I actually thought about doing that, using engine torque to try and break it loose. Was kind of nervous to do that though, didn't want to make matters worse! The whole purpose of this was to replace the output seal on the transfer case that was leaking. Didn't go as smooth as planned (imagine that!) but got 'r done. Thanks!
