I've heard Richmond can be noisy. But the overriding consensus is that's nonsense, opinion is, it's likely just a poor pattern or lack of proper pinion preload.
I went with a 3 series Eaton Posi. I will be using Super Shims on the carrier, and ditching the crush sleeve for a solid pinion spacer and shim.
Should all be here within 3 weeks (the Moser axles are backordered).
Looking forward to this rebuild. The rear end bushings are so toast, the rear end sounds like it's about to fall out over bumps.
I'll make a small post on the build.
Cheers,
