My 89 has the stock axle and I bought Warn's premium manual hubs (part # 20990). The problem is that when I put them in it seems like they stick out a little bit and need to go in another 1/8 inch to put the snap ring on the outside of the hub. I know some of you have encountered this problem, so I'd like your input. Do I have the correct manual hub or do I have to buy the conversion kit also? FWIW, the hub is on tight (no play in the wheel) and the lock ring is correctly seated.
