Differential Whine (Revised Factory Diff with Cooling Fins?)

lewie145 · 03-17-2015, 12:26 PM

This is the pic of the "revised" differential with a new cover design that someone allegedly had replaced under warranty in CA, as you can see it is not the nismo diff cover and was replaced on a US car, just weird that I cannot find out any other information on this anywhere.

I guess i will just take it in Thursday and see what the dealer can come up with.

The car did have an intake when i purchased it but has the stock exhaust system and cats, stock suspension, no wheel spacers either. I find it odd that someone would mod the differential or install differential bushings before modding the exhaust, suspension, or adding wheel spacers.

that is not a finned diff cover. it is the finned differential housing that comes in warm weather climates such as the UAE and australia. some australian's can chime in here
