Is this normal?????
I installed my 4.10 ring and pinion into my 03 gmc this weekend and i hear that it is making a whining noise when i go between the speed of 45 and 55 mph, and thats it. No other time do i hear a noise! It is not loud and i have to cut the radio off and pick the windows up to hear it. I installed it to the spec that the company (motive gear) sent me. I set my backlash to .010 and set my pinion load to +/-2 just like they said. It also track like the picture showed in the diagram when i put the marking paint on the gear. Also i changed the bearings that the kit came with. I'm just wondering if this is normal and the noise will go away? I do not even have 100 miles on the gears yet, and i do not want to ruin them.

Just my 2 cents, but I think even with the perfect install, your going to get a certain amount of whine from aftermarket gears. If you listen hard enough even some stock gears whine a bit. If its just a low whine, I wouldn't worry about it. My Richmond 3.90's whined something fierce in my old crew cab. I doubt the noise will go away completely, but will most likely soften up slightly.
If you are confident that you installed everything correctly.

i noticed a whine in my stock 3.73 gears at certain speeds at a certain throttle. i used to be a tech for jaguar, every single car had a tiny whine at certain speeds with light throttle. its amazing what some old people can hear. anyway i think i a little whine will be normal expecially with aftermarket gears.
