Hi,
Noticed oil from rear of car .so sunday jacked car up and had a nose appears my diff seal is weeping and when I turn light to the left I can hear a faint rubbing noise .I have booked car in for tomoz morning for the work should I replace diff fluid with Diff fluid w/fm booster part#8 22 2 282 583 when seals are done any views will be massively appreciated Im not remotely mechanically minded but have read this fluid is really good.
