Just changed my 05 CRDs rear diff fluid and replaced it with Moble1 75w90 stuff and it seeks to have a slight whine now. I added the additive also, even though i'm not sure I need it. Maybe I should have used 75w140? Anyone else have this problem? |

do you tow anything? if so, shoulda used at least 75w110 (not available from Mobil, only Amsoil) though it calls for 75w140 for towing. at the least I would have used the 110 even if not towing. |

I don't tow a whole lot but once in a while I do and I might be pulling my buddys boat more seeing as he just rolled his truck heh. I think I'll use the vacuum and suck out the 75w90 and throw in some 75w140. I don't see a point in removing the cover since I just changed and cleaned it last weekend. But do you think the light oil might cause increased whine? I never noticed it before the change but my girl friend has been driving it since I just bought a TJ. |

I'm pretty sure I posted something in here about that, bad news it might need servicing. My rear end needed a complete rebuild, warranty though. Wont hurt to take it in if your the original owner... Now when asked if you changed the fluids, you can say yes I did, when you visit the dealer..

Sorry, but until the locker went into my KJ, I never ran more than a 75/90, despite occasional towing. Rearend's never made a peep. Could just be that the thicker fluid kept it quieter...but you have a problem now...so you'd better get hoppin on fixing it |

Well it is a slight noise it's hard to notice if your not listing for it, the girl friend can't hear it but you know how that goes. I guess I'll try the 75w110 and see if that helps. Thanks. |
