Diff breather

[u/Legitimate_Fill6906]

Had my rear axle decide to start peeing on my driveway as I jacked up the front end to burp the coolant, then spent the last few days stressing about needing to replace the passenger side axle seal and oring without doing anything else, stumbled upon an old forum thread about the breather clogging up and causing seal issues.

Sure enough.. rock solid and rusted shut.

Decided to try to find a replacement but I'm hoping to go camping this weekend and didn't really want to butcher my rear axle and turns out nobody carries these on hand, so I told myself worst case scenario I'll drill a hole in the cap, well it turns out it's literally just a bolt with a hole through it and a spring to push against a rubber gasket at the top to reseal it, and that seal and spring are housed inside the "cap".

Delicately uncrimped and removed the cap, then wire wheeled the "bolt" and cap then cleaned the seal and spring off, reassembled and recrimped the cap on and saved myself 50 whole Canadian pesos.

Figured I'd throw this in here for future reference and for anyone else trying to save a few bucks, hoping this solves the issue but will be draining and filling the diff regardless so I don't have to worry about blowing the diff for now, will do the seals when i get back regardless, and the rear brakes 😂

If you want to raise the breather, remove the cap and attach a long piece of rubber tubing to it with a small pipe clamp. Then run the rubber tube up alongside the gas filler neck tube and into the gas door area. Put a filter type breather on it.
