Okay I am trying to get my 1/2 shafts out to replace the U joints. I figured the real tough part was going to be getting the bolts loose on the flange side of the shaft. Got that done but I cant figure out how to get at the u joint cap nuts to get them loose. I cant get a ratchet or breaker bar into the confined space due to the differential housing getting in the way. I have spun the shaft around in different positions but cant find a spot that works. I can get a 9/16 crescent wrench on the nuts , there is limited space to turn the wrench plus the wrench is way too short to get any decent leverage on it to loosen the nuts. And yes I sprayed PB blaster on them several times and let it sit for well over a week soaking before working on it. Any tips on this?
