whine on decell any ideas
so i just put 456 in the fromnt and rear and new 35 km2s i am at about 250 miles in the break in and there seems to be a whine at around 20-25 mph and onnly on decell
i have read what randys has to say about noises in the tech area. but theres nothing about decell noise. im sure its from the front as a gm tech pretty used to diff noises i was wondering if any else is running km2s and if so fo they sing when decelling and why do i hear it more from the front. . she has 4 inch lift tera flex upper rears and 6 speed any ideas
thanks for feed back in advance

i had km2s and no whining noise from them ever. could be a nember of things not sure if you installed the gears but to do so requires to tear the entire axle down. might be wheel bearings

Several situations can create ring-and-pinion noise. If the gears have been quiet and begin to howl, they are probably worn or wearing. If the gears howl during deceleration only, it’s possible that the pinion-bearing preload has loosened. Howling under acceleration at all speeds indicates that something in the differential -- gears, pinion or carrier bearings -- has worn or no longer keeps the gear alignment correct. If the gears howl while accelerating over a certain speed range, but not all speeds, it’s likely that the gears are worn due to lubrication failure or overloading. When a newly installed gear set howls, suspect the design or setup.

SWEET thanks for the artical and feed back i did the gears my self and ( I think im a chevy tech or atleast thats what they pay me for) anyhow randys sent me usa standard gears and after install i found that they state that they might be louder
than other gears (you would think that when a guy calls and wants to spen a grand or more the person on the other end would let them know of this ) so its not getting louder but i know its just not right gonna open r up and take a peek next week keep you posted

It turns out gears fine km2s are bit loud usa standards are a bit loud and found out yukon doesn't make 456 so 488 would be better way to go.or another brand for now just gotta expect noise
