SRAD Strut

My front strut (left side only) is leaking fluid... Do I need to replace the whole strut or the seals inside of the strut?

I would go ahead and do the whole fork service on both legs. Check everything isn't bent or damanged, replace seals/oil. See if that clears it up.

Fork seals will leak over time. A couple of questions:
How many miles on the bike? If its high miles, go ahead and change both seals. If its low miles, figure out why it is leaking and, like Trip said, check for damage. Unless you stunt a lot or ride in dusty conditions, a set of fork seals last at least 20k miles.

^+1.... you could have dings/scratches on the fork tubes... in that case, new seals won't do anything. Hopefully that's not the case though.

I have 21k miles on it. Is it hard to replace seals and oil if you have common sense for mechanical repairs?

Never done it myself, but I know there are a few special tools you'll need to save your self a lot of headaches... That being said, check out the Maintenance section, I beleive there is a tut or two out there...

If you get the service manual and are slightly mechanically inclined, you should be able to do it, from what I have seen.

The special tools you may need and/or want are a seal driver, some nice long hex extensions to get at your damping rod screw, a spring compressor (if you have inverted forks), an oil level gauge, and brake cleaner. At 21k miles you probably will want to replace your bushings as well, check the surface to see if they are worn.

COMPLETELY remove from the bike and disassemble the forks, and get all of the gross chitty oil out of there. Clean all of the compenents individually with brake cleaner and let them dry. Then reassemble, get those new bushings on all the way, grease your seals and drive them in, fill to the proper oil level with fresh oil, and throw the forks back on the bike.

Write down your adjuster settings (rebound, high/low speed compression damping, whatever settings your forks have, etc) when you take the forks apart because you will forget. This is assuming you have them set up properly beforehand.

Careful not to lose parts... snap rings especially are a bitch to keep track of.

An impact wrench and a vise will make life much easier. You'll be one mad s.o.b. trying to get the caps off without one of the above.

Good point. A decent vice to hold the fork in place while you break it down would be helpful.

And if not an impact wrench, a breaker bar would probably work nicely.
