I have a leak on the rear right weel. The fluid is being sprayed around the inside of the tire and is building up on the bottom of the brake pad. I believe this is a hub seal leak from looking around on the forum. Brake fluid levels haven't changed.
Strangely, this happened right after I added a "homemade" (read, 3 ft of fish tank tubing) breather extension to that axle. As far as I can tell the breather line is clear, even with the extension. The extension tube is transparent so I can see that there are no obstructions there.
I can blow through the tube, though it does take some force (I'm assuming this is because of the sheer length of the tube - about 5 ft). When I connect the tub to the axle and tighten it down I can blow in the tube, but not for long b/c pressure builds up within about 1-2 seconds. I'm assuming that's because the entire axle & diff are sealed & that the fitting is not blocked. I've visually inspected the fitting and it looks fine.
To be safe I've removed my breather extension, but the hub still seems to be leaking.
Am I missing something? Is it just a coincidence that the hub is leaking right after I started working on the breather tube?
