and....one more little note
Some of the "rope" seals out there right now come all powdered up with a graphite looking powder and Guess What? They install DRY--wet one with some oil and $%#@*&% You have an oil leak anyway.
That info is also not included with some of these seals so you may not be to blame when the gusher starts.

Again I feel like the main issue is with crappy Fel Pro seals that are a shadow of the former part quality--Go with RoadHazzards premium part and hope for the best
