Guidance on servicing Shimano R550 wheels

[Acyclo]

I've just acquired some old Shimano WH R550 wheels. I'm seeking help servicing them. Can anyone point to definitive help and advice?

The Shimano web site has some help, exploded diagrams etc, but it's all rather terse. Thanks.

What seems to be the problem with them? Do they wobble when spun? Do they feel 'sticky' when spun? Wheel maintenance can be tricky to learn but it's a good skill to have, apparently (I'm still trying to learn).

 

[Acyclo]

Yes, they're slack. I can feel it.

Do you mean the spokes are loose? Does the wheel appear buckled, rubbing on the brake pads, when spun?

 

[Acyclo]

No, it's the bearings. The spokes all seem good.
