Will used 4.10 gears whine?

[mvvette97]

I put some in the other night and have them set up right I believe but it still whines at about 55 or 60. Some people say it's because they are used and the gear are now in a differant wear pattern, like the ring and pinion are not matched up to the same teeth as they were originally. Is this true?

it may be that theyre used.

although, i think it matters more whether theyre aftermarket or gm gears. from what ive heard, aftermarket gears tend to whine, but gms dont.

but hey, thats just what i heard

Kind of scary when you say you believe there in right. I'm guessing something is not aligned right. But for my opion I wouldn't have put used gears on mine.
