How to: Checking Differential Breather on Samurai.
If you have a leaking pinion seal on your differential or leaking axle seals it could be a clogged differential breather that is causing the differential to leak. The differential breather is located on the top of the differential. It may be a press on breather or a screw in. In either case you should be able to pry off the cap on the top of the differential breather and remove the rubber flap and see if the differential breather is obstructed. Many times these breathers can become clogged with mud when going off road and that will cause the front or rear differentials to leak from the pinion seals. The real solution is to install a differential breather hose and run it up high and put a filter or one way check valve on the end of it. In the case of the Suzuki Samurai a 9/16 inch inside diameter hose could be clamped over the differential breather and that could be used a differential breather hose.
