Spartan locker problems need help!

Installed a spartan locker in my front D30 not too long ago (about 50 miles ago). I am however having some issues and can't figure it out. At first had issues with axle shaft u joints but got that figured out but am still getting lots of popping and half time won't unlock when making LEFT turns only. Right turns no problem but lefts make lots of loud popping and banging. Can't figure out why only left turns. Help please!!!!

What were your tolerance measurements before you pulled the spiders? If you failed to take the proper measurements then I'd go back and do it right. First I'd pull the locker back out completely and make sure it's not damaged and that it was properly installed the first time. If that all looks good I'd pull the carrier and make sure the bearings are good. I had a bad carrier bearing on my 8.8 and it did the same thing. Look for excessive scoring on the rollers and races, if you find anything out of the ordinary that's most likely your issue. Another thing could be that the carrier holes that center pin go through might be sloppy, I'm guessing you did buy the locker specific center pin as well correct (no cut outs)?

Yes I got the center pin. I don't remember the exact measurement but was within spec. Guess maybe bearing. No idea age of bearings as it jy axle. Is there a breakin period for a lunchbox?

No, no break-in. I have a couple of Aussies but I'm pretty sure it's out of tolerance if it's skipping on one side. That means that there's a significant difference between the two sides.

I know this thread is old, but Snoopi what ended up being the problem and how did you fix it? I'm having the same problem with my dana 30 spartan locker, installed about two months ago, except my popping sound comes when turning right mostly. Thought maybe I had a broken cv joint on the pass. side, but you said you replaced yours and still had the problem?

Popping with an Aussie type locker are usually caused by the bad bearings (out of tolerance per side) or tires of different heights. Both are easy enough to diagnose.
