Just a hint to avoid trouble when you go to put the final c-clip on after the wheel locknuts; mine didn't have enough room, it was like the axle shaft wasn't "out" all the way. It was so close though, tempting to hammer the c-clip in but inside I pried on the u-joint and got the clearance I needed.
When doing the other side, I found the culprit;
It's the new grease on the axle shaft seal for the spindle and extra air being trapped forming a kind of suction/pressure point that doesn't allow the axle shaft to slide outwards enough. Once you're on the road and the axle shafts are spinning, all that grease will be worked in and everything will settle in nicely. It's not like anything is binding.
The solution I found is that when you go to put the spindle back on the knuckle, pull the axle shaft out as much as you can (without the other end falling out) and then slide the spindle on it, twisting it as you slide it on fully. This will settle the grease in, then you can slide both the spindle and axle shaft onto the knuckle. Once I had everything back together, I pressed the c-clip on the end of the axle, there was plenty of room, nothing tight but just loose enough.
