[QUOTE="Fred W, post: 1356645, member: 3828"] The reason the seal starts leaking to begin with is that the seal lip[B][U]s[/U][/B] get contaminated with road spooge and bug guts that get plastered on the inner fork legs, and then works its way down under the dust seal to the oil seal. You may not be aware, but the oil seals actually have a double lip. If after cleaning the seal it is dry, even for just a short time, that's good as it tells you that the seal is not damaged. You really need to make sure the seal mate slips under both of the lips when cleaning to get all the spooge out. You also want to diligently clean the upper part of the seal that you can get at (Q-tips are your friend) the inside of the dust seal, and the inner fork legs. I seriously doubt that the small amount of dirt that might get past the seal would cause too much of a problem once it has fallen into the large quantity of fork oil inside the fork leg. More likely you just aren't getting all the spooge out of the seal. PS - FWIW - I have found I can do a much more thorough job of cleaning the seals with the fork legs off the bike vs when still mounted on the bike. Of course that isn't always practical, like on the side of the road in BFE. [/QUOTE]
