Wheel bearings

My drz400 has 17,000 miles on it. A few questions:

1. How long should the wheel bearings and swingarm bearings last?

2. Should I replace them now so there are no problems in the future or are they expected to last much longer?

3. What has been your experience with how long these last?

4. The piston and rings were replaced by the previous owner at 15,000 miles. Is there anything else I should consider doing because the bike has 17,000 miles?

Thanks.

Do u use your bike in the mud and dirt? And use a pressure washer to clean Ur z? If so I would inspect them. It's not very hard for grit to find it's way past the seals once they are worn.

Bearings are cheap, a failure won't be.

I do and I'm pretty hard on gear so I'm on my third set in 7000 miles.

I don't pressure wash the bike. It is ridden on dirt. It never goes in mud.

Pull the wheels and take a look. I bought my S with 15,400 on it not that long ago and changed the tires and found the front bearings were in decent shape but the rears were horrible. The spacers are scored really bad, the seals are shot and the bearings are lightly rusted.

The only way to tell is to pull the wheels and have a look. Depending on where and how you should clue you in to haw often you check them. I beleive the only way to may the seals and spacers last is to pull them every once in a while, clean the seals and spacers and regrease them.
