New Gears
So I just got my rearend back together after 2 months of money and research but apparently I didn't learn enough. The pinion depth is right and the backlash is .009, the problem is that it still howls under deceleration and when I turn right. The carrier doesn't fall out like it did before but I don't have to tap it in and it doesn't take much to pull it out. Could it be that even though the backlash is right, if there aren't enough shims in there to keep the carrier from going side to side, that would cause it to howl especially when I turn? Need some help. They are new Motive 4.10's

Anyone? I got a performance mag for fbodies and it's saying that the cast iron spacer that comes in it stock should be put back in. Well I didn't put it just new shims. Could that be it?

Read this Yukon Gear Installation Manual http://www.yukongear.com/Downloads/M...structions.pdf
And this from Randy's Ring and Pinion, last paragraph particularly. http://www.ringpinion.com/TechnicalH...n_Settings.inc
It sounds to me that you don't have the carrier shimmed tight enough with the side shims. When I built my rear I shimmed the carrier to as tight as I could get it as per the above manual. Don't worry about overloading the bearings by shimming the carrier tight in the rear housing, those tapered rollers can take enormous loads.

So right now that my backlash is good, but the carrier can just slide in and out, can I add the same amount of shims (equal thickness) on both sides enough to get a pretty tight fit and that should fix the howling sound under decel and turning right?
