I am having some issues with a Full float conversion that I purchased from Herm. Over the weekend, I stripped the splines on my short side axle. It appears that the axle pushed the snap ring out of the back of my warn hub. This allowed the axle to work its way out and then strip 1/8" off the splines. I removed the hub, cleaned the splines up with a file. The power lock was disassembled and inspected, the side gears appear to be fine. Reassembled with a drive flange this time, it appears that the short side axle is 1/8" to 3/16" too short. About 6 months ago, I scored a set of ecj5 axles for $100 on craigslist. 27 with a powerlock and a offset 44 rear with powerlock and full float kit with locking hubs on it. I felt really stupid after spending nearly $1000 only 6 months earlier, and threw them in my parts stash. Yesterday I tore down the rear axle I found that both rear axles had snap rings on the outer ends. In addition to the snap rings, they had a couple shims on each side to keep the axle pushed further in. On top of that, the short side axle was 1/8" longer than the short side axle that I received from Herm.( just what I believe I need) The long axle was the exact same length as Herms. I now understand the reason for the snap ring on the outer end of the axle is to give the drive flange or hub something to push against to retain the axle in the two gears in each side for the powerlock. The additional shims allow you to fine tune the axle depth. My axle kit as received from Herm did not come with any snap rings or shims. I pulled the powerlock out of the craigslist axle and found that it still had the center pins installed. When I installed my full float conversion I removed the center pins from my powerlock. What is Herm's reason for removing the center pins? The craigslist axle still has the center pins and appears to have been working just fine.
