I am getting ready to replace my rear axle with a new Lonestar unit. I wanted to freshen up the carrier bearings at the same time so rather than pound out the old and in with the new I decided to just buy an entire carrier with new twin row bearings. Seems like a quality piece but I have a question about the inner spacer, it has a seam weld going right down the middle of it. The stock carrier spacer does not have any seam. It looks like the axle won't contact this piece so it is probably fine but just wanted to check with a few of you guru's first.
