Review on Yukon Gear YA F880038 Differential by David Silva

You'll need pins and a tool to install them, but it's a lot of fun! It only took me 15 minutes to install these studs! These waves are great! Let's see how long they last. I always change all bearings/seals every 50,000 miles and my original ones have done 190,000 miles. I also only use Royal Purple 75w-140 gear oil. Nothing but the very best!
