air lockers

I recently swapped my non-rubicon axles for rubicon axles with stock air lockers. My front axle locks up no problem, but my back won’t lock. I’ve tried swapping pumps, replacing air lines, using an air compressor, replaced the pumpkin and air actuator, etc., and it still won’t lock. I’ve also...

If anyone is interested in looking it up, I can't seem to figure out how to link it. There's a 2006 TJ built up at our local Ed Morse Chevrolet GMC dealer in Sierra Vista az. Under used cars, there's only 2 Jeeps. I think it has 124,000 miles on it 🤔

So I’m looking at doing a re gear on my axles and I was wondering what years did the tj have air lockers for the rubicon. (My axles were swaped) And I was also wonder if I could use the factory air system and just hook it up to arb air lockers, any help would be appreciated

I have a 1999 TJ Sport which I understand has a dayna 44 rear axel with True Track difff. In the intrested of moving forward (no pun intended) with limited funds, should i up grade the front axel to air locker now and try to get by with the rear with true tract. Thanks for any input! Dennis
