Just noticed that my left shock on my 06 Honda crf450r has decided to leak on me. How hard is it to replace the seals? Do I only need the seal, dust seal, and oil to do the job? ( i have access to the 47mm seal) driver). Any help is much appreciated

Just my 2 cents... if you have it apart, replace it all. And do both sides at the same time.

Is it leaking because the elastomeric seal failed or are the sliding metal surfaces scratched? If the latter, new seals will die an early death.

You will need to disassemble the forks. Not hard but time consuming for a novice. Do both sides. Fork oil will need replaced. Get a shop manual. Try to find seal kit that uses "SKF" brand seals. They outlast others 2:1

There's some good videos on youtube.

Do you have basic mechanical knowledge? Can you tear down your bike? Do you have a decent set of tools including the correct seal driver?

If so, have at it. A pretty simple job overall.

Try that plastic scraper cleany thingy first. You might just have dirt in there.

My Kaw was doing the same thing. I just told the old girl to stop it and ran that thing up her skirt a few times.

Seems to have stopped it. Either that or it's dry.

here's another version.

Like others have said. On those bikes the job is pretty straight forward if you have the correct tools. I would probably order new slider bushings as well if it's been ridden decently hard. It sucks to get the forks apart and realize the bushings are wasted and have to wait to order them.

Also, check you pm's.

sliding surfaces look to good, It appears to have happened when I was trailering it to the dunes and forgot to stick a block between the tire and fork.

Thanks for the help! pretty simple job overall, bushings still had a decent amount of copper on them but I will change them out next season. Took me an hour on both shocks so overall pretty easy

Sorry, I'm a newb when it comes to bikes. I only recently switched from race quads to bikes. In my defense though forks are technically shocks

forks seals are pretty easy to do, a little bit of a messy job but not terribly difficult. and if you're gonna do one fork arm you may as well do both since you have to take the front end apart anyway.

I've rebuilt the exact same forks twice. It took me a good hour or two the first time, taking my time. The second time I did it in my driveway in about 30 minutes, just seals and new fluid.

Super easy job to do. It's intimidating for some the first time, and messy, but it really isn't that bad. You can make a ghetto seal driver out of PVC pipe and some U bolts, but spend the money and buy the correct size one for your bike

Oh, you're a quadtard. You're excused.
