Topic: Weird crawler chatter after spartan locker instal

[slander]

So i just installed an fzj80 rear axle with a spartan locker and took it out for its shakedown run this weekend.  When driving down the highway (55-70mph) and i let off the gas i hear a noise almost like when the 4wd lever slips back and starts hitting the gears, but that isn't happening.  I have a crawler with a mc07, "noisy" gears, with a lefty gear drive case behind it on my tacoma.  The setup has almost 50k on it, fluid came out clean last time i changed it (i got home last night and have not drained it yet).  There were no unusual noises prior to the axle swap.  The only thing i can think of is the locker ratcheting and sending vibrations through the drive-line and i am hearing it in the crawler.   

Has anyone had this problem or heard of it?  Worry about it or turn up the radio?

Are you running a CV rear drive shaft?

Its a cv driveshaft, i'm also running an fj80 rear axle, but it has no drive line vibes.  The noise has went away, so i guess its wait and see if something blows up time.
