Detriot slack

[1-tonmudder]

I have a no-spin Detriot locker in my 10.5 14 bolt with a 4:88 gear and I am pulling the stuff from my truck and putting under my CUCV.I pulled the 14 bolt today and noticed it has quite a bit of slack in it(less than a 1/4 turn) before it locks up.The locker and gear have maybe 8k on them and the gear still has a good pattern and the grease still looked good.Is this normal due to wear,or do I have a problem.I have never heard a noise from it,(that I could hear over the boggers) and as far as I know has always locked.The parts were bought new and set up by a reputable gear man that has done work for me before,and never had a problem so I dont think it's that.This was found by turning the yoke and not the tires.Anybody have any ideas.

detroit locker = 1/4 turn play in drive line.

It might have been there all along but I just now noticed it

My Detroit is the same way, it's been like that through 2 housings, 3 ratios and 20 years. It's the nature of the product, no worries.

To learn why it does that, go to my web site at
http://www.angelfire.com/super/ThunderTruck/Technical.htm and click on the "Automotive Locking Differentials" link. It's a 1+ MB Word doc, but well worth the download if you want to really know what's going on inside the diff.
