Review on 🔧 Yukon Gear & Axle YGK013 Gear & Install Kit for Jeep JK non-Rubicon 4.88 Ratio - Optimized for Enhanced Discoverability by Edwin White

Good: everything you need is in the box. Seals/bearings/extra pinch bushings/gear color/new bolts The guide is laid out well for those experienced with this type of installation. It took me and someone more experienced two full days to completely overhaul both differentials and U again to set up -Links in a well-stocked farm shop. (This included a trip to the parts store, lunch breaks, and beer breaks) The Bad: Yukon's torque specs for the Dana 44 (55 ftlbs) and Dana 44 JK (125 ftlbs) sprocket bolts were misleading. I'm working on a JKRubicon that has a D44 front and back, but the front isn't as strong as the back. We took the "jk" specs, tightened the front to match the back and screwed in before realizing we needed D44 specs. The rear of the Rubicon uses larger screws that can take the load, while the front has smaller ones that cannot. Luckily the included screw failed before the holder/ring so she was salvaged. I just think the instructions should say "Dana 44 JK Rear/Rubicon". Ugly: The drive gear, bearing cage (and even their chromoly axles) were chipped and damaged. I would like to slide the axles towards the UPS as they were loosely wrapped in plastic and could rattle when handled. But the race and gears were very well protected, soldered and wrapped in foam with the boxes intact. I could only assume it came that way from the factory. This next mistake is beyond me, so get over it. According to my mechanic and his boss, the gears should have been engraved to some prescribed depth after being tested at the factory. They have used this information on TJ, JK, Ford and several tow vehicles in the past to help with their own projects. I was very upset with this kit however, a couple of home made jigs were screwed onto my axle housing to confirm their suspicions and after a few measurements and some head scratching I was told to "throw those numbers out". Automatic transmission for Toyota 35x12.5x17 AT. Up to 17.5hwy 1900rpm at 65mph with lots of downshifts. After 16.5 hwy / 13 city 2500 rpm @ 65 mph and he doesn't care about the hills anymore. With no throttle, moderate trails require 1/4 the amount of skinny pedal to get up. So much torque on the ground, it's unbelievable. Commuting and hard days on the trails and I haven't heard or felt any awkward noise front or rear and imagine if I hit the 37 I'll still feel like I have plenty of energy.
