After the locker engaged there was no air leak.
Is this common? it seems to be leaking only when the piston moves to lock it. also leaking from the inner portion of it... not the air ring that inputs the air.
Also.... the Poly pros I guess were the bad batch. the left rear was so worn at the bearing I had to use a sledge hammer to get it out. The bearing is trashed. Right side looks OK.
Tomorrow I call poly pro. we'll see what they do seeing as these are axles I bought from somebody else second hand. New, but second hand.
So, should I pull the diff and tear it apart too?
Good luck dealing with poly. Driver side poly axle on my truck was trashed like yours and getting anything out of them at all was a major pain. Same thing, trashed driver side after a short time, happened to another Slee customer who bought the axles new from him but didn't replace the wheel bearings at the time of axle install. Poly wouldn't replace a thing for that person under warranty since the bearings weren't new. My bearings were new with the poly axle install and the driver axle lasted fewer than 5,000 miles. Axle had a gouge/groove in it over 1/8" deep and poly made me pay for all shipping to and from them and that was only after Christo had a long phone conversation with the owner to get them to replace the bad axle. I've replaced the rear diff oil half a dozen times now and am still getting sparkly crap out each time. Probably looking at a new ARB seal before too long and I'm not holding my breath that the replacement poly axle is any better than the first pos. Should have stuck with the OEMs with 200,000 miles on them.
