Is there any way to discern if the noise coming out the rear is the differential bearings or the gears going bad. I have 3.23 gears on a 98 Trans Am with 125xxx miles. It whines going down the road at idle as well as at any rev point.


On another note I get a ping noise every time I shift directional gears (From P to anything, from Reverse to drive, from neutral to drive, etc) I believe is the U-joints. I also get a tapping feeling in the gas pedal while accelerating. I dont believe its related but you never know.

What do you guys think? ]]> nhraracer http://www.ls1tech.com/forums/gears-axles/1207351-differential-bearing-old-gears-noise.html New thread! http://www.ls1tech.com/forums/gears-axles/1207338-new-thread.html Fri, 20 Nov 2009 23:24:19 GMT has any one ever went from a 4.10 to a 3.73 in an m6 and had better results in performance? has any one ever went from a 4.10 to a 3.73 in an m6 and had better results in performance? ]]> ODAWG http://www.ls1tech.com/forums/gears-axles/1207338-new-thread.html Hit a Curb.... http://www.ls1tech.com/forums/gears-axles/1207290-hit-curb.html Fri, 20 Nov 2009 20:50:19 GMT im sure i bent the Axle Shaft should i replace the hole rear end or should i get new shafts, ball bearing ect.... btw im still using my factory rear end. im sure i bent the Axle Shaft should i replace the hole rear end or should i get new shafts, ball bearing ect....

I have set the pinion shim to 0.020" and backlash to 0.009". I feel that I need to take some pinion shim out and move to 0.015". I checked the pattern and think it is not that good. I know the axle housing can mess with the the pattern and the flank to face is the major concern in the setup. I am just not happy with the set up. Plan to rework some more.
Any thoughts on the pattern? Thanks

The problem i am having is that when i left off the gas and turn the steering wheel towards the right while making a turn, the rear end makes a weird grinding noise. And the farther towards the right i turn the louder the noise gets. It sounds like the posi unit but I'm not sure. And this only happens when making right turns while the car is decelerating. Does anyone know whats happening or how to fix it?? Any help or comments would be great!!

Will the tubes interchange, and is it possible to use c-clip eliminators on the trans am with the factory rear disk brake set up? I know I will need to make a tq arm mount also.
