REVIEWS & CUSTOMER MEDIA
Installed these chromoly front axles in my 2022 Jeep Wrangler Rubicon at the same time as installing new Synergy ball joints. The u-joints and yoke that come with these axles, Spicer 5-1410-3X, are significantly larger than the OEM u-joints and yoke. It fit perfectly, but it definitely makes access to the top of the lower ball joint a tight fit for greasing. I do not believe a taller lower ball joint, like the Teraflex HD, would fit with this larger ujoint - it would be very close.

Added these with my Reid Racing knuckles for my 38" tire upgrade. They fit perfect. However, when running Terflex Ball joints. They did not clear. So I had to smooth (grind) down the ball joint a bit to clear the outer stub shafts. Other than that they work. Instructions should say what ball joints they work with.
