    Prorock 44 leak(s) Need Help

    I have a Prorock 44 with a 35 spline ARB locker and RCV shafts I bought here in Wisconsin from a vendor. The axle has about 3000 miles of mostly street driving and the last time it was wheeled was December of 18. I know the leak is new (today) because I installed a metalcloak lift about a month ago and there was no leak. I have gear oil in 2 places. One is at the knuckle near the rcv shaft but the other is puzzling and it is on top of the tube I think near the diff. I have no idea how this is leaking. I do run 37's also but have had no issues until now. First off please tell me how difficult it is to replace the seal? Do I have to pull the locker? DO you usually replace both seals? I also have heard 35 splines eat seals. Not sure if this is true but I hope not What parts do I need to fix this and what is the deal with the leak at the tube? Any advice / help is appreciated.

    The leak near the diff looks like something above it dripping on it. Power steering or the coolant reservoir overflow. The one at the knuckle looks like an inner seal possibly.

    The one by the knuckle looks like a classic inner axle seal leak. Haven't experienced that with my PR but I had that same looking leak on my old JKUR. From the research I did with that one yes you have to pull the carrier to replace that seal and will need some sort of long pipe to pound out the old seal. I didn't end up replacing them in my old Jeep before selling it so can't help much there sorry.

    The other leak though I would agree it looks like something dripping from above. Maybe try cleaning that one up and catch it sooner might be more of an indication of where it's coming from. To me it doesn't look like it's coming from the tube or the plug welds and maybe just maybe a small leak from the cover with driving wind could spread it up on top like that but a cover leak would be an easy fix especially since you will need to pull the cover anyway to get to the inner seal

    Agreed with the others... Check your steering gear and trans cooler lines just above that general area. Probably the steering gear as the trans lines are probably too far forward to hit the axle.

    What color is the fluid on the diff? Lightly press a white rag and post it. It looks slightly pink in the pics.

    Call Dynatrac before working on it yourself. They have a 12 month no-fault warranty.

    Dynatrac will take care of it. We recently installed a PR44 with 35 splines and it immediately leaked. They sent out a new immediately.

    Thanks for the replies folks. Its been in for more than a year but I certainly will take any help they will give. It certainly has not been wheeled hard and that is the truth. I like doing what I can but this one is a little beyond me. Id love to watch the guy fix it because I think it may be a trend but now I have to find that guy to fix it and the parts he will need. Thanks again!

    I have the Spicer part number you need at the shop. If I don’t post it back up here later then you might try calling me at the shop and I’ll give it to you. It’s a $10 seal, with about $250 labor at a reputable shop.

This is a lifestyle that transcends age, gender and race as the only thing you need to be a part of it is a love for the outdoors, a desire to explore, a yearning to take on a challenge and a will to conquer it. Over the years, Cindy and I have attempted to capture the essence of this lifestyle through photographs and videos and share it with others around the world. And, this is how WAYALIFE was born.
