Gear Install - Now Whines
#14
Rear end gears don't need a break in period. After you get them up to highway speeds just once after leaving the install shop, the pattern is set.

You're the victim of a bad install. If he had set the backlash correctly the first time, you would have no whine. Unfortunately, after you drove with them in for a while at the improper backlash setting, they established a wear pattern that caused the noise to continue even when adjusted to the proper backlash (if the mechanic even reinstalled them, which I am suspicious of). There is no "noisy" gear ratio. All gears should operate silently and any mechanic who tells you otherwise does not deserve your business.
To the op: spend the money on a good install and be done with it. It's not worth your time or piece of mind to put up with noisy gears.

I want to believe that so bad. I'm going in for a gear and differential swap and really want 4.30's, unfortunately almost all the feedback on them is to expect noise. I'll ask my gear guy about his experience with them. I've been the victim of a bad install before and this guy knew what the other shop did wrong and was able to install dead silent gears for me.

I did the same thing as Bruce and was very happy about it. If you have the time or connections, talk to people who race at your local drag strip and ask them who they have used. It's what I did and it worked out really well for me.

I promise you, that's the way it is. I worked in two automotive performance shops before hurricane Katrina. The reason I quit the first one was because the owner (who also did the gear installs) had a bad habit of giving customers the runaround every time he did a crappy install (not just on gears, but on anything). If a mechanic won't warranty his labor for a gear install against gear whine, find a new mechanic.

I remember the trouble you went through with the dealership. Is this your second set of 3.73's or did they just reinstall the first set?
