You're due for the fork oil and service! About every 15,000 miles or 2 years.

Two special tools are needed to do the fork seals. )ne can be made with a length of PVC, and the other with a piece of all thread, and a couple of nuts. Get a manual, and review the proceedure. Looks a little scary, but is fairly easy.
When you go to order the parts the fische says you need two kits to do the job. It is wrong. One kit comes with everything for both tubes.

BTW white lithium has the bad habit of wadding in the cable housing. Get a pproduct called "Cable Life" along with the aplicator. The cable will pull better, and last longer
