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. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/87710197-spartan-locker-for-dana-44-not-d44-hd-30-spline](https://www.desertcart.us/products/87710197-spartan-locker-for-dana-44-not-d44-hd-30-spline) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-15*
