I'm in the process of swapping my 6 lug front 10 bolt to 8 lugs and it already has warn premium hubs installed. I started on the passanger's side 1st, I removed the allen bolts and pulled the outer piece off, and out came the inner splines with a large thin spring behind it, I removed the outer retaining ring, then used 2 of the allen head screws to help pull the outer splines out..........finished the swap then bolted it all back together, but now the hub lock is very hard to turn. I went to the driver's side to see if I re-installed something out of order, and found that there is no large spring behind the inner splines - what gives? is there supposed to be a spring only on the passanger side?
