Just wondering if anyone had replaced their leaky pinion seal with the revised 'triple lip' seal? (GM #: 26064028 )
If it'll seal better, I'm interested - but from what I see, this seal is a two-piece design, and requires either yoke replacement or a special sleeve adapter to accommodate. That sounds like more trouble than it's worth, especially concerning getting the bearing crush / lash set correctly with a different yoke, w/o replacing the crush washer outright (requiring disassembly of the diff, and all that entails).
If anyone has put in the 'triple lip' and retained the original yoke, & no adapter... I'd like to hear from you, especially about setting the lash and how it worked out, long-term. Didn't see any mention of it when I ran a search.
Leaning toward just getting a '1st design' one piece seal from a good company like National and calling it a day. The OEM lasted until about the last year (?) or so (when I R&R'd the fluid a couple of years ago, the outer housing was dry as the Sahara). FWIW, this revised seal is considered a valid replacement for all 8.5" / 8.6" rear diffs from '99-up, not just for our 360/370 platforms.
Not a serious leak yet, but want to get it replaced before it gets that way. Thanks.
