I’ve read all over online that the rear diff. breather can get stuck causing pressure buildup. I just noticed that my diff is leaking oil right where the axle goes into it. I’m assuming a seal is bad, or the pressure built up and started forcing its way out. I looked EVERYWHERE and cannot find this breather valve!? I have a 2010 Rav4 Base 2.5L AWD. Does this model even have one?? I’ve seen pictures online of the diff and they point out where this breather valve is and when I check on mine, it’s not there. What am I missing? Thanks!!
