One of my fork seals has blown, and it is leaking oil slightly. The last time this happened was 3 years ago with the *other* fork seal. At that time, I'd the dealer do the repair--costing over $160. The mechanic recommended that both seals be replaced so I OKed the work. Since the current leak is with the *opposite* seal, I'm suspicious now as to whether this seal was ever replaced back then--might just be a coincident but it does make me wonder... This time, I am going to replace the seal myself. Anyway, what is the best practice--replace the leaking one or both seals? Any input would be greatly appreciated.
Both fork tubes go up and down at the same time don't they? Wear on the seals' lips will be about the same and the one you don't replace will probably start leaking sooner than later... Since you have to hoist the front end of the bike off the ground and remove the front wheel, why do that work twice? Replace both seals at the same time...
Thanks for your inputs! These were the same rationale that the mechanic made three years ago for doing both seals at the same time. I already have two seals on hold for me so I'll be replacing both tomorrow. Thanks again!
there is a bushing in top of the lower fork tube. right below the seal. replace it also same time as seal. you'll be glad you did. ............................. Motorpsycho Jim
Thanks for useful advice guys! Actually, there are two sets of bushings: outer tube guide bushing located at top of outer/lower tube, and inner tube guide bushing located at bottom of inner/upper tube. Should I replace both sets too, or just the pair of outer tube bushings? Thanks again!
