So last year I took the plunge and bought a metric G2 Core 44 front axle housing since I managed to bend my front housing on my 2012 JKUR. At about 5000 miles I had to swap ball joints since they went out, I cant remember the brand but they were included in the axle. These were swapped out with some Synergy ball joints which I found out also need to be replaced. I am using the stock knuckles and other components with 37" Pitbull Rockers. Any ideas why this would need to be swapped out so quickly? Pretty much my entire front end is new sans the rubi-locker, calipers and axle shafts.

 

Running spacers? How much wheel backspacing?

 

Yes to spacers 1.5 inch Spidertrax due to the aftermarket metal-cloak tie rod. Normal backspacing is 4.75.

 

your net back spacing is 4.75" or the wheels are 4.75" back spacing? What brand were the ball joints? Were they mopar?
