I know this thread is about 3.55 gear but this is my story as George mentioned Yukon.
I bought a ring and pinion, 3.38, from Yukon and it whined big time. I'll admit they sent me another and to my surprise it was WORST than the first one. They then told me they didn't guarantee it anymore! I then put the first one back in and sent the worst one back.......they then said it was because I ordered a 3.38 so go figure. I'm out my money and have a whining ring/pinion. We just never know............
EDIT: just to make it clear, I had a professional do the build. A guy who has built more ring/pinions then 98 % of other guys. Big trucks to rock crawlers to work for other dealers..... so it wasn't me!!
