I have a 2005 KW mule that front u-joint went out in. Besides cracking a couple of yokes I notice that the yokes even though they look alike some are marked “A” and some marked “B”. What’s the deal ? When I ordered yokes they never call them A or B. Will they work. I know the new u- joints I ordered before I cracked the yoke came with alimites, are there going to be enough room and can you get a grease gun on them? Looks to me the answer is NO. Help please , my yokes will be in this Thursday coming.
