I've been hearing a low pitched rumble coming from somewhere when i used the brakes. I couldn't tell if it was the front or rear so i pulled the handbrake up while i was rolling and i could still hear the noise so determined it was coming from the drums on the back. Not a horrible noise, but its there.
So took off the left hand side drum to check the shoes as i figured they were worn, but didnt see any issues....went to the other side and found this as seen above.
Diff grease pissing out of the half shaft, so new bearings for that side im assuming? (Im right in thinking that there are no seals, as the bearings are the seals themselves, right?)
Only did the opposite side last year because of the same symptom (grease leaking out, there was no rumble then though), so im guessing the grease has found a new path of least resistance and is now leaking out the opposite side which has weaker and older bearings, probably not the ones with the correct raised rubber seals.
As i turn the wheels however i can hear the sound of cogs turning and you can feel it through the axle, am i right in guess this is the crown pinion in the diff? Is this normal and something to do with the fact the car is up in the air and theres no weight on the axle, or a sign of a bigger problem?
Im assuming the oil level most be low inside too by now? It never makes a noise while im driving though, literally only when i brake which i find strange.
Didn't think the axle did any kind of braking so not sure why i only hear the noise when the rear brakes kick in, but this leaking must have something to do with it? Could the grease on the shoes be making the noise?
Guess i should have done both bearings on each side at once when i did the left hand side last year i suppose, but budget and time was likely the reason we didnt.
At least i know which bearings to get now!
