I am having a run of bad luck with my front locker install. Im building my Dana 30. I trussed and sleeved it and welded gussets on the c’s. I purchased a 30 spline Eaton elocker 4 for my Dana 30 from Quadratec. The first one they sent was a 27 spline locker. They corrected the issue by sending a 30 spline locker. I grabbed my driver side 30 spline shaft and verified the fit. I dropped my Dana 30 off at my local trans. Shop and had the locker installed. I picked my axle up and brought it home. The drive side 30 spline shaft installed no problem. The passenger shaft would not spline up. Long story short, I removed the carrier and discovered the drive side of the carrier was 30 spline and passenger side was 27 spline. WTF MAN! This has cost me a month on my build, 2 sets of bearings, $30 in dif oil and my sanity. I had to cancel my birthday rock crawling trip. Has anybody ever heard of this happening before? I will be contacting Quadratec bright and early come Monday. They better make this right!
