Hi Folks,

I'm new here..I just joined the forum the other day. My wife and I own a 2009 Tribeca and I am making plans to drain and fill the gear oil (front and rear). Subaru calls for GL-5 75W90 gear oil, but the manual does not state if the gears are limited slip and if it requires an oil that needs the LS additive.

So, do I need a gear oil with the limited slip additive or not. I don't even know if this vehicle has a limited slip differential...I can't find anything about it in the manual.

Thanks in advance for your feedback...great forum, really glad to be here.
