Alright this is gonna be a long post.
A while back I have zip lockers and 4.88 gears installed in front and rear 44s for my MJ project. I just got it up and running and went through the break in process for the gears as my installer recommended (Robert @ Rwkhaussupply).
When I first filled the diffs up I put in the factory recommended amount of oil and they both puked oil, at the time I thought it was over serviced since its a full case locker. So I pulled out a half quart of oil and continued the break in.
After the break in I changed the oil and only put in 1.5 quarts. Only driving on surface roads to work every now n then the rear diff wasn't spitting out oil anymore so I thought the issue was resolved.
This weekend I took the MJ on its first wheeling trip that was about 150 miles round trip with mostly freeway there and back. I noticed some oil had come out the rear vent and made a mess. I drained the oil out today and I lost a half quart of fluid from the diff leaving only one quart remaining in the diff. If anyone has some advise I'd love to hear it.
Some things to consider to help me resolve this issue:
-I did a search prior to posting on here and know about the relief that needs to be made in the rear for better drain back (my installer mentioned this step). I couldn't find much about this specific locker only ARBs pretty much.
-Its a rear 44 from a 91 grand wagoneer
-I have the breather vent moved to the top of the diff cover since I put a truss on the axle and the stock breather hole is blocked off.
-I have a Ruffstuff diff cover installed
-It doesn't seem to be leaking air in the diff since the locker stays engaged and my compressor doesn't kick back on.
-I have about 3' of breather tube that leads high up into my bed.
-The pinion is rotated up a few degrees since I have a 5.5" lift and a SYE installed.
I contacted the installer as well but it's Sunday so I'm waiting to hear back from him. Anything helpful will be much appreciated.
