Never mind, misread RD142 as RD124

ARB has changed the design of the air locker carrier. The seal housing is now on the opposite side of the carrier, compared to earlier units. Allegedly it is being done this way for less parts and lower production costs.
I preferred them being on the non-ring gear side of the carrier, but after setting up some of these, you can easily route the air line so that it will not touch the ring gear or the axle housing when the center section is installed into the axle assembly.
Concerning the copper air tube routing:
I agree with the other folks who have posted up stating that the copper air tube needs to be routed higher on the housing. You do not want to bump into something with your differential cover or front axle and have the housing dent/bend and then cause the air tube to meet up with the ring gear.

good idea ...
at least i know i have the right part... thanks for the Phone#.

Biggest problem I had with that air-line config when I did mine 2 months ago was getting third member back in axle without bending the air-line back into the ring gear. It's heavy!! I ended up suspending the third member with some ratchet straps so I didn't have to support the weight and could just guide it into the axle housing. Worked great the first time (after four other tries) and had no rubbing.

actually, nils did a good job, but ...
the install went different. first attempt the tubing was rubbing on the ring gear. i took a lot of care to do the first try. on the second try, i re-measured the cavity between the axle housing flanges and sure enough i had the tubing to far back towards the front of the vehicle, front axle, so i reaccessed the situation and decided to move the tubing to about 1 inch from the thrid member housing at the top. this placed the tubing in the channel formed by the axle housing and slipped it in for an inspection mirror look see. sure enough, it cleared all the way around the ring gear.
i still feel that drilling a hole at the front top of the axle housing, just above and to the inside of the ring gear for the purpose of reaching in and pulling the tubing clear of the gear and securing it from vibration would be the trick.
one thing i do not know, is that the tubing is not rubbing on the inside of the diff housing/axle housing when bolted up. i tried to use my smallest inspection mirror and darkened the room to try and see throught the add oil port, but could not confirm. i need one of those small inspection cameras that would go through there for that. putting it on the "to buy" list now.
so here we go. hoping that i get enough arb locker engaging off/on's to do the job. at least next time, i'll know to remove the complete axle, and work on it on the bench. ugg.

sorry, here is the picture...
of the space where the tubing seems to need to be located when install the RD142 into a fj40-69-30 spline axle.

Bolt it up and stick your ear in the fill hole. You'll be able to hear any rubbing when you turn the pinion.

yup ...
i did that, and i also put my finger on the end of the air line that sticks out of the fitting and there was no vibration there either after reset of the tubing and second install.
thanks for the confirmation of a good idea. listening.
