How do you take off the u-joints on a '97 Wolverine? We have the shaft off. Do you take the nut loose so the whole yoke will come off then press them out, or can you knock them out while they're still on the atv? It sure would have been nice if they had clips like a truck. If the nut has to come off, do you have to use a special thin wrench, because there isn't much room to get a regular wrench in there? Thanks.
