Lunch Box Slack???

Anyone here running Lunchboxes front and rear in stock axles?
I'm Running a loc-right in my 30, and a No-slip in my 35 out rear, and when i go from drive to reverse, or vice versa i have a lot of slack, it makes a loud clack noise.

It was first noticable after i installed the rear one, as it went in 6 months or so before i locked the front. Anyone else have this? should i worry about damage, or is it just an annoyance?

Thanks.

if your getting torque steer I bet some of your control arm bushings are shot.

If everything else feels good, check the transfer case chain.

Im pretty sure all my ca bushings are finished, the torque steer showed up after the no slip went in the rear, step on the gas and she pushes to the drivers side, let off it and it goes to the pass side. Im ordering all adjustable ca's, just have to get the money together. I'm also waiting as i have to replace my front diff since its bent on the drivers side and my tire has a serious camber issue. so when ill install the new d30 and the arms all at once. How much is a t-case chain? or where would i order one from?

That sounds like pretty standard driving characteristics of a lunchbox locker to me. The increased slack is due to the extra clearance around the carrier pin. In the stock diff the pin is snug in the carrier. With the locker there is just a tiny bit of play back and forth. I bet you've also noticed that if you park on a hill and don't use the e-brake that it rolls a foot or so further than it used to...It was scary the first time I felt it!

The torque steer you're talking about sounds normal too. Worn bushings could definitely make it worse.

I had a lock right in a samurai and in neutral I could twist the drive shaft a lot. If the sound started when you did the rear then I would be concerned about the sound because you did not have a lunchbox locker then. Make sure your tc is in neutral when you check your drive shafts.
