so I'm looking at buying a new mud truck. its a 91 truck newer paint, no rust frame is mint, front end upgraded to all spicer components ( ball joints, tie-rod ends, bushings, etc), 4 inch procomp stage 3 lift with all upgrades available and airbag helpers, 3 inch body lift (guessing performance accessories), 212,000 km on vehicle 42,000 on motor, 3 inch fender flairs, 35x12.50 BFG mudders on eagle alloy rims, re-geared with 5.29s.

apparently this truck has an ARB air locker in the rear diff but needs a compressor and its good to go. i know that the ARB's are fed air through an air line but i have never seen one in real life so i would have no idea where to look for the air supply line off the locker.


what i want to know is can i tell if there is an arb in the diff without having to drop the diff out of it?

a picture is worth a thousand words :hint hint:

thanks a bunch

 

yeah there is air fitting on the diff. its copper hardline in the diff...

 

See the little red cap, under that is a brass fitting for where the ARB line connects. That is just an indication there is an ARB in there but no way to be 100% sure without pulling the diff.

 

yeah i figured that that was the only way to know 100% but i was just looking for a way to check when i go look at it again this week
and its the same with the rear diff on the same side and everything too?

 

Should be pretty close to there if not exactly in the same spot.
