USA trains passenger car wheel upgrade

[steveavaughn]

Hello!
I have USA trains aluminum Sante Fe passenger cars. The wheelsets are awful. They have a brush on the wheels for lighting pick up.
They are constantly squeaking. I have used electrically conductive oil but to no avail. I have many sets of new LGB ball bearing Wheels with electric pickups on them. Can I put those on? Thank you!

Where is the squeak?

Axle bearings I assume. Try a little grease on the stubs where they locate in the bogies.

If the LGB wheels are of the same diameter as the originals, then try them.

You've nothing to loose....
