I've been thinking about putting one in my 89 Formula. While talking to one of the guys at Moser he stated that the gears they use make a "little" noise. Do any of you guys have one that can give me some personal feedback on the noise factor? Thanks

 

slight hum at crusing speed, not a big deal, but I have experienced clunking when coasting at high speeds (like 60-70) but I have the detroit true track posi, seems the axels run free when no load is on them from the tranny. which from what they told me is a gear driven posi and not a spring posi??? 'm still trying to get a good answer on how to improve this.

 

The noise factor is mainly in the type of gears you get and the setup. Any improperly set up gears will make noise. I had 3.73 US Gears in my Moser 12 bolt originally and it was very quiet. Richmond gears tend to make more noise because of the cut, I have 4.30 richmonds now and it has a very slight whine, nothing loud.

 

I was considering the tru track but maybe not, don't like the idea of clunking. Thanks to both of you.

 

i have the tru-trac in my 9", its very smooth, no clunking at all, i would recommend it.

My rear is a tad noisy, mostly when you are off the gas and coasting.

 

Well i have a moser 9" if that helps any and mine makes lot of noise it's something moser is known for.

I'am also detroit true track user and have to admit it is a very agressive locker but I like it a lot and it is still streetable.
