well, i'm now starting to hear weird noises from my diff at low speeds (1-10mph). i'm getting very wary. i don't know if it's a big deal, because it sounds like the regular gear whine from the 4.77s, just a lot slower. just in case, i want to get another diff as a backup. please PM with offers

 

get a ap2 diff

 

I have an AP1 diff on the Mid A Swap that needs a rebuild. You can get it pretty cheap compared to buying a used one and do a rebuild yourself. PM me for details
