Will the new complete truck replacement parts (622XX-OODO2) fit on an older DC model Spectrum 44 tonner?

Thanks

Tom,
Thanks for the quick response.  This unit is a Spectrum with two motors and DC.  I don't know the date of mfgr.  Bought it for cheap on Ebay.  I may go ahead and pull the gears to see if they are cracked.  If I can establish that one or both are cracked, I will order new gears.


Have had the motor units off the frame, but have not attempted to pull the gears.  Anything I should know before I try? 

Thanks again.

Joe

I have a Bachmann GE 44 tonner that runs good but is exceptionally noisy.  The drive gears are clean and have been lubricated.  Upon close inspection (as close as my old eyesight permits) it appears that the axles/wheels may be out of square.  On both trucks, one set of wheels seems to be "bouncing" or rotating in an oval pattern.
Is there a recommended fix for this problem? Are there replacements available?
I like the loco and have a place on my layout for a light duty industrial switcher, but the noise is certainly unattractive and un-prototypical.
