2009 Mazda B2300
31,000 miles
5 spd manual
Axel: 3.73 gear ratio with a 7.5" Ring Gear
So I crawl under to check the spare tire pressure and once again notice an oil leak around the rear axle vent. It's not new and I can not tell you when it started. I did change the dif lubrication at 21,000 miles. I took some pictures and it appears that it's leaking from the axle vent connection. I can understand the need to vent the axle, but it seems if the vent was working there would be no pressure build up in the axle and no need to leak. So if I pull off the "rubber cup", what will I find? What is the procedure to diagnose and correct the problem?
