Welcome to the Michigan FBody Association website.
The Michigan FBody Association is a centralized website for FBody enthusiasts to discuss what's going on in the Michigan area. MiFbody.com was created to allow for an easy one-stop place to find out what's going on in Michigan as far as FBody events, to find out what clubs are available in your immediate area, and for an easy place to post classifieds for items you want to sell! Our goal was to create a more close-knit community of FBody enthusiasts in the state of Michigan, and to bring Camaro and Firebird enthusiasts alike together for some amazing FBody events!
The most important thing to know about the Michigan FBody Association is that we are NOT a club! The Michigan FBody Association is open to everyone, and is a community. Thus, we will have get togethers, casual cruises, events, and such like that, but this is not an exclusive club and it's 100% free to join this site! So what are you waiting for? Register now!

I have a Moser 12 bolt, and a 3:73 gear, also a custom aluminum driveshaft. Right before I put the car away for winter it started to make a noise. It sounds like the driveshaft is loose, maybe the U-Joints, could this happen from it being cold out? I've never really dealt with a rear end, or any of the stuff there. So this is all new to me. Maybe someone can come look at it? I'm lost with this thing.

If your close to 12 mile, i could have my dad look at it hes a master mechanic, and deals with transmissions and rear ends as his job.

The car is not at my house. It's at my parent's. Which is 15min. away, I'm not really worried about it now, as it's winter and the car won't come out of storage until it's warm. I just thought I'd ask so I can get a rough idea.
2 guess based on your description and where the noise is. 1. u joint, and 2. trans mount. tail of trans would be right there. But we all know how sounds travel.

how often do you tighten the torque arm bracket?
I bet it is loose.
describe the noise better
Thats a good suggestion too.
One way to distinguish u joint sound, they make noise when going bad under load or power, shift to neutral and coast a bit. if noise stops could likely be u joint.

torque arm bolts will loosen over time if not loctite'd. i found this out just hitting them with my impact one day when i was under there and didnt even realize they were loose.
the 4 bolt mosers have issues. I have made it better but still have them.
I have shims between the houseing and TA bracket to limit the clearance. before you the bolts would tighten but the tightness was just from the bracket tweaking. the bracket would never actually clamp the housing without the shims
I have now tack welded the head of the bolts to keep them tight. I broke two of the tacks this year
Well it was doing it while I was driving it on Friday, so therefore I think it's something with the driveshaft or rear-end. Larry (Plum Nuts) mind taking a look at it? Maybe next time on Woodward, I'll take you for a ride too.
