the noise is coming from inside the diff... man im really bummed out about it. i just changed gear oil with lucas 85-140, but u can still hear the noise. when i took off the cover i did notice that the teeth from the pinion were already marked on the ring gear.. im thinking to much preload..? the pattern was dead on center though so i guess thats a good thing.. i dont even have 1 mile on the axle but im already getting burned out from all this.. been working on it for almost a year and havent been able to drive it.


members on naxja are telling me that it might be normal for a little while?? any thoughts..?

Actually though the wear pattern will tell you everything you need to know.

what are you suggesting? you think i shouldn't worry and take it for a drive in the freeway?

setting up rear axles take some time heres a pretty good write up hope it helpshttp://www.differentials.com/install.html

No you said it already has a wear pattern. Look at where the pattern sits on the ring gear, how even it is, look for metal shavings. Be an investigator. Sounds like you might want to start over on tour set up. My friend did gears in his 9" back in high school for the first time. They lasted like 200 miles.

heres a video of the sound.

heres another video..

Wow that's a nice sound. Sounds like they aren't meshing right.

That noise can't be good. I would think a do-over is needed.
