Yes, a Lockright or any auto locker increase driveline freeplay quite a bit. With a numerically high diff ratio like 4.89 or 5.83, it can approach 50-60 degrees. The Lockright has I believe 16 or 18 teeth (same # as side gear). with 18, that's 20 degrees per tooth. Figure 1/3 freeplay, 7 degrees. Multiply by 4.89, add some for freeplay in ring/pinion, pinion/yoke, side gear/axle - it can get up to 50 degrees. The diff won't work without the freeplay.
