How often the ARB pump should run?

#1 06-22-2009, 09:01 AM

I have an ARB in my front axle (Dana 60). When I engage the pump and locker on pavement, the locker will sit in "locked" state for a while before the pump will kick in again. When crawling in 4low, the pump will cycle on quite frequently. Looks like I have a leak in there (but only under load), just trying to figure out what's the culprit before digging into it.

I have turned on my F&R ARB's at the trailhead and left them both on many, many times, and the ARB pump will not cycle for several hours. Or maybe around lunchtime 4-5 hours later.

My pump operates like Joe described his does ... it runs when I first turn it on, but after that, it doesn't come back on all that much.
