Regearing and rebuilding my axles

[RedRoad]

I recently did the 44 on my K20 as well and X2 on everything Chris said. The only issue I had with mine was the outer seal/slinger. The 44 on my truck was a first series which used the bronze slinger, the available seal kit comes with a plastic one which was the wrong diameter. One of them was scored badly but luckily I had a core with a single good slinger to donate. I was able to get USA Timken wheel bearings at my local autozone, maybe just old stock.
