I did't know that, thanks. Brakes are good, but not sure how that works. I don't see anywhere the break T goes into the rear end. Attached is what I have. I'm not the first oner and this may not be the original rearend.
I have a 2003 Jeep Wrangler. It has no rear differential vent. I assume it had one and for some reason the previous oner welded over the fitting. Can I simply weld a fitting on the differential cover near the top and attach a vent hose there?
