Whining rear end I just installed a strange 12 bolt rear end. When i was getting into the throttle the rearend got louder and louder. 
Than i would back off the gas and it wouldnt make anymore noise.
What could be wrong? I bought this from a friend.

Correct me if I'm wrong, but aren't Strange Gears more noisy than other Aftermarket gears? I know all aftermarket gears, depending on the quality of the install are going to be louder than stock gears. How loud is it?

I talk to the guy that sold me it. He said it was noisy for him too. I have never had aftermarket gears before so it got me worried. I am going to change the gear fluid to see if that helps.

Yukon, Superior, Prescision, Spicer etc..... All have been utilized in applications with no hint of added gear noise over the stock Jeep gears made by Spicer. IMHO, the whining is coming from an improper setup on the gears and backlash. I've heard Moser sets their rearends up "tight" from their factory to make the rear stronger but will result in more noise.
I run auto lockers in my Jeep application and when locking and unlocking they make a ratcheting sound that is muffled somewhat by using a 85W-140 gear oil over standard 75W90. HTH

I am friends with chevy94c and a mechanic.
I drove the car yesterday an dthe noise is better described as a HOWL especially above 40 mph. it is very loud to the point that it echos off of the jersey barriers on the side of the road.
it also has noise coasting to. just not as constant
this sounds just like a 8.8 i rebuilt last summer where the pinion bearings were so blown that the pinion was "digging" into the ring.
I think he needs a ring + pinion, bearings and a decent setup.
I will do it for you mike, but i have to buy a universal pinion depth tool. I only have ones for fords.

When I bought my diff from strange in 2003 it was so noisy out of the box friends told me they could hear me coming 1/2 mile away.
I was sent a replacement gear by strange but had to pick up install costs.
Still makes noise thought not as bad (US gear )

I spoke with strange today. They said change the gear oil and check the backlash. They told me the 12 bolts are louder than the OEM 10 bolt. This doesnt sound right to me.
Hopefully svttech can check it out soon. I really want to drive it around.

My Moser was dead quiet until I started beating on it with QTP's. Ive driven over 2000 miles on them now and its spewin diff fluid all out the drivers side axle, from the vent tube, and still loud but it aint hurtin nothin. I just keep puttin fluid in and keep beatin on it
