Moser 9" gear noise advice please!!
Hey all, I just finished installing a Moser 9", Tru-trac posi, 4.11 gears, 31 spline axles, weld-in LCA relocation brackets, c-clip eliminators, and aluminum center section(just so you know what im working with), and I am experiencing a fairly good amount of gear noise, both speeding up and idling down. My 10 bolt was whining only on idling down before it failed. What can I do to fix this, or is this "normal" for a performance rear end? I've been hearing that "some" noise is to be expected, but how much is normal, how do i know if it is too much or a bad sound?

It was installed as is. Had a guy at napa check the backlash while he was pressing on my bearings and installing new u-joints, he said it was .009, which was fine for the band i called and got from moser (.008 - .012). I've heard something about a yoke or pinion(cant remember) adjustment; can it fix the whine?

It is is indeed the gears, chances are that it was assembled correctly and you just happened to get a st of gears that are louder than most. It does happen, you can have to sets of gears that have an identical pattern, and one can be quiet and the other one loud. In this case the only thing you can do is to remove the center section and send it back in to get another set of gears installed. Bob

IONO, the decel noise might be a preload problem on the pinion bearings. Lockers clunk and make all kinds of noises. can sound like the rearend is gonna fall out(totally normal).

When I changed out the spider gears on my wrangler I replaced the pinion seal as well. Torqued the nut down incorrectly and experienced a growling noise when driving. I backed the nut off and retorqued following the correct spec and it took care of the problem.
