Noisy ARB air locker?

So, I've been chasing down this noise I've had since my axle install. I've finally narrowed it down to the ARB air locker. I thought it was the tcase but that is a different noise that I'm not concerned with right now. Below is the response I got from ARB saying it is normal, which is fine by me. I just couldn't find much other info on the web about people having this issue. Any of you have this clicking noise on accel and decel? Almost sounds like a light ujoint.

ARB's response:



And here are the diag steps I did before contacting them:

Huh, I've never heard any noise like that from mine, front or rear but then my wife is always saying "I can't believe you can't hear that!" so what do I know. I have heard the racheting style lockers make noise but only when going around corners.

Those ARB guys are solid. I talked with a rep at length last year for over an hour. They don't seem to be a company that'd bust your nuts over this issue, especially since you've documented it. If they aren't concerned I'd roll with it.

It's been a LONG time since I've run an ARB up front on anything other than an axle with manual locking hubs but, so far as I can recall, I had no noise coming from it. But, if they say it's normal, it probably is and really, my hearing isn't that great anyway :crazyeyes:

Thanks for the comments so far. And as I said in my email to them, as long as it's just a noise and nothing else, I'm good with it.
