any tips on getting these knuckles and u joints apart on my 44? cant seem to get to the nut i circled. looks like im going to need a bigger wrench for one as biggest i got is 1 1/8" and its bigger than that. or does it take a special tool to get to it? once i get that nut off i should be able to drive out knuckle right? i got the top nut off and the c clip off bottom one. is there a c clip on top one? i didnt see one. any advice or tips appreciated.
