Are Yukon Gears noisy?

Hi guys,

I put a set of Yukon 4.88's in my 8.8 last week. This was my 10th set of gears I have setup now, and I have noticed that the lower ratio the cogs are, the harder it is to get a good pattern.

Anyway. My pattern was pretty nice (no pics) but it was pretty much centered from Face to Flank, and ran almost the entire length from Heal to Toe on the Coast Side, and was slightly centered closer to the Toe on the Drive Side. Pretty much ideal according to the Yukon Instructions. All Bearings, Races, etc are new. Pinion Bearing Preload was dead on at 17 inch lbs. Backlash was set at around 0.010", which is a tad tight, but has prolly opened up to 0.011" by now. Carrier Bearing Preload was pretty much the same as when I pulled the Ford 4.10's.

So, after driving around, following the break-in procedures, I have got a howl that starts at around 25 mph and gets louder with speed, but goes away almost completely over 60 mph. Accellerating with a Heavy or Light Foot, Decellerating etc all have no effect on the noise. I have even thrown the tranny in Neutral at 50 mph and coasted.... Same, same.

Its not a horrible Howl, like when my Dana 35 started to die, but it is a bit troubling considering the meticulousness of the whole setup/installation. I have webwheeled around and read a fair number of comments about Yukon Gears, especially 4.56 or lower being a bit noisier that the taller cogs. Is their any truth to this?

Scotty

I have not had any problems either. You could try running redline oil in the diff. I ran it in my Shovelhead 4spd. tranny & it quieted it right up & made it shift smooth.
