## Questions & Answers

**Q: Will these fit my 1995 jeep wrangler yj?  should i put them on the front, back, or both?**
A: Yes this will work very well in your front High pinion Dana 30.    

You would need a different locker for the rear Dana 35 in your YJ but i would personally not put an auto locker in it.  You will break the dana35 easily.  

if you really want a locker for the rear - consider swapping the axle for a ford 8.8 or even a  dana 44 out of a waggoneer

**Q: will this work on my 87 xj?**
A: Yes, this locker will work GREAT as long as you have the Dana 44 Rearend.Let me know if you have any other questions.Thanks,BRYDON641-751-8060staticz2229@gmail.com

**Q: Will this fit my 2007 Jeep Unlimited with Dana 44 rear axle with no additional shims or parts?**
A: Yes this should fit in your 44 using the same shims you already have in there.  This will pop considerably on pavement in your rear diff.  I have it in my front and it behaves like an open diff when in 2wd.  It locks up in 4wd and becomes stiffer to steer but climbs rocks much better.  I have the D-30 front.

**Q: Does this locker make noise on tight turns?**
A: Yes, all lunch box type lockers make a clicking noise on turns.  On slow tight turns you may occasionally hear and feel a loud banging.  I have this locker in my front D30 and while turning into a parking space I turn slowly and don't accelerate while doing this type of turning. As others have said, it's normal.
