Rear Deore XT Derailur jockey pullys hard to turn.

I have an '88 or '89 Alpine Monitor Pass hardtail MTB with all
Deore componetry. While I was cleaning & oiling the chain I
noticed that the jockey wheels on the rear derailur were hard to
turn. I sprayed their axles with Triflow which helped some, but
they still are not free spinning. Turning them has the same
resistance as turning a spoon in honey.

What I am wondering is what should be done. Do I need to
disassemble the rear derailur and lubricate the jockey wheels ?
How? If so what do use oil or grease? Should I replace them with
Bullseye pulleys or an equivelant? All advice is much
appreciated.

A fix might hold you for a while -- in which case, you can use grease.
A new pair of pulleys might cost your $30-40.

For $40, I'd probably buy a new old stock Deore rear derailleur and be
done with it....

Correction (to my other post). Here's a Deore RD for $21

Shows you how to take care of the jockey wheels and the rest of the derailer. If it is 17 - 18 years old it may need the service.

Interesting that they seem to recommend oil for Shimano and Campy
pulleys and grease for Sram. Why is that?

Be careful that the guy on ebay isn't selling his NOS derailleur
because the jockey wheels are old and stiff to turn. You might end up
right where you started - stuck with having to perform the horribly
tedious and humiliating 5 minute procedure of cleaning derailleur
jockey wheels.

The triflow won't get where it's supposed to because the jockey wheels
should have rubber seals to keep stuff out.

Lubrication should be the only required solution.

Definitely a light oil such as Prolink. Triflow will work, but it will
likely gum it up in the near future. The Prolink will loosen up any
gunked-up stuff in there, and it'll clean off more easily before you
reassemble.

Not worth the expense.

It's easy to remove the wheels. The bearings are usually just bushings,
you just may have dirt and perhaps some corrosion. Remember which one
was the top wheel, and screw the bolts back on pretty tight so they
don't loosen later.

After market wheels are usually more expensive than decent derailers --
don't bother.

Your old low-level derailer may just be shot, no great loss, newer,
better ones are available for little $$.

Take off the chain, clean it and while it is soaking, take off the
pulleys, clean them, pry the seal off, add grease, reassemble.
 
When the pulley wheels have to much play I replace them.
But till then I take them off, clean and repack them with grease
no matter Shimano or Sram.Which I have both 6 Sram one Shimano.
