my rear end started making this weird noise, sounds exactly like when a thorny bush scrapes against the paint. i just installed a sphon torque arm and i checked and rechecked it for any signes of something being wrong, but nada!!

this happens occasionaly and it doesn't seem related to turning or not.

any ideas what could be going on???

Recheck your pinion angle...if it is more than -2 degrees (or even around -2 degrees) it could be binding the U-joint and making some noise....usually you are safe up until about -2 degrees....but check your measurements. Good luck!

I had the same noise. Checked everything under the car at least 10 times. Turned out to be a damn sway bar bushing. It only did it every once in a while, but it could be something easy like that.

This is from the Torsen website:

Torsen for GM vehicles:

Is it true that the Torsen unit in the production Camaro needs the GM modifier added?

GM issued a technical bulletin adding modifier to the rear axle oil. This was done to quiet what we call a "Rusty Screw" noise that we heard in a very small percentage of vehicles. This does not happen in all cases, however to address owner's concerns we asked that the modifier be used in all instances to insure that the driver would not get this noise. When replacing the fluid it is at the owner's discretion whether or not to add the modifier. Elimination of the modifier does not affect durability of the differential.
