Now for the stem bearing replacement.
We’ll use the later-model retainer-equipped ball bearings.
I personally like the light feel they give, and they seem to last longer.
Maybe it’s because there’s more space for grease to get in?
This is based on our shop’s clinical results.
Please don’t take it as gospel, though.
We also use the later-model seals—the GSF’s stock seals are just plastic with no actual sealing function.
Upgrading to a proper seal makes them last much longer.
Of course, applying grease to the lip area too boosts performance a bit.
Once you’ve worked grease into both top and bottom, spin it—spin it—spin it.
It’s not about bleeding air out, but working the grease in thoroughly all the way to the back really does make them last longer, I think.
After that, change the fork oil and you’re done.
