i just swapped out the differential as part of my famous auto-manual tranny swap, and the first 100 miles everything was great, then today i noticed a slight rumbling sound from the back. it went away every time i accelerated, and started rumbling the minute i let my foot off the gas. it got progressively louder over the next 25 miles to where the only time it doesn't make any sound is when i'm hitting the gas.

i'm thinking i got a bogus ebay rear-end. i had an open 3.91 (i think) so i got this 3.23 lsd.

can someone give me bit of knowledge on this? any tips to help me diagnose this will be used!

Either a whriiring/whining sound, or a light grinding sound
