I've experienced boot leak issues that may help you "slingers". I had both inner boots start slinging the goo. I went lazy mode and had my Indy re-boot all four. I noticed a few weeks later it was slinging AGAIN! As under warranty, the shop had another go. The tech explained, the factory style clamps are a bugger to get tight enough and they've seen this movie before where factory clamps are notorious to loosen. The second round has been fine for months.
I wonder if clamp grip pressure is your issue not an undersized axle? I've read where DIY's have used stainless worm-screw style clamps and cranked 'em down with no balance or leak problems. Just suggesting you re-clamp before condemning the axle.
Anything made can be made Better
