I had a very respected Mopar guy who runs a tranny and rear end shop rebuild my 489 pig. He advised against the 3:55 gear because he said they don't cut the teeth the same way as they used to and they ALL howl now regardless of brand. It just affects the 3:55 gear set for some reason. He also said that if I was determined to go with the 3:55, the best thing to do was find NOS factory gears.

Anyway I went ahead and they do howl around freeway speeds. I thought I could live with it but the gear reminds me its there over and over again. So now I'm thinking of 3:73...

Anyone else heard of this?
