[QUOTE="lulu62, post: 2021612, member: 66733"] Hey guys, I'm Lauren. 2010 scab here with my second diff leak in a year. Clearly my repair last time didn't do the job - looking for guidance on round 2! Backstory - 8 months ago, I noticed a slight diff fluid leak on the rear passenger side on the outer end of the axle. After some research (lots on this forum!) I figured it needed a new axle seal. Well.. I was kind of right. When I took the wheel off and axle out, I noticed that the actual axle housing was slightly warped at the bottom (photo attached), which caused the seal to not sit quite perfectly. While I was in there, I replaced the bearing and seal for good measure, but was still left with this housing fitment issue. I decided to go with some JB weld around the outside in hopes it would seal off the gap. Well, 8 months later, I started smelling diff fluid again and when I crawled under the truck, it was drooling diff fluid in the same spot. I'm guessing my JB weld blew. Before I go in and do it all again, wondering if anyone has solutions other than replacing the whole rear end? Is it worth trying to get the housing shaped back up? Should I go with motorcraft RTV instead of JB weld? Speedi sleeve? Is it possible to replace just the "cups" at the end of the housing? A bit at a loss here. Appreciate any help or advice. Thanks guys! [/QUOTE]
