Differential lube??????

Jan 11, 2004 12 Replies

What type and viscosity lube oil should I put in my differentials. I have a Corporate 14 bolt in the back with a detroit locker and a Dana 44 up front with a ARB air locker. I would like to change out the oil, but don't know what kind to put in. I would like to use a synthetic, but I don't know what range or brand.



Thanks for the help

I'd use whatever the factory put in. Synthetics are a waste of money. (At least in the axles.. despite the hype, you won't live long enough to notice the difference.) Your lockers are gear-type, not friction-plate type, and don't need any friction modifiers.

75W90 Mobil 1 Synthetic, or 80W90 Valvoline Durablend.

I have synthetic AMSOIL gear lube in my rear diff on my 98 Sonoma 4x4, that stuff is really good....look into using it.

I just did the front and rear on my '99 Silverado 4x4. Thats what I used.

Adair

That's is what I wanted to use, but I wasn't sure if you needed to use something different due to the locker. Thanks for the help

Can you give us details on the improvements you've experianced?

Had I known what a rude person you were I wouldn't have even responded. Jerk.

Doc

I'll second that notion, what improvements over dino or synthetics have you seen?

Doc

Jerk? This guy was completely rude to me. Sorry I didn't see it post the first time, it never showed up so I posted again thinking I did something wrong. Then this asshole goes and tells me how inconsiderate I was for posting twice. I thought the purpose of these newsgroups is to help others out. Sorry if I don't know everything.

But I do appreciate the help from those that offer it. It's unfortunate there are those out there who are too busy finding peoples mistakes.

Don't worry about it....... there are a lot of folks around here who act before they think. Sometimes things get lost in the few words posted here. I try to help here and there.... sometimes I'm wrong or may have mis-understood the question. Like you say this forum is to share information and help one-another. I try to refrain from making judegments of others. Some folks are just learning about the newsgroups and may not see the "way things work" before they post, but thats not a big deal anyway.
