HO heavy weight passenger car trucks crumbling.

Has anyone else had a issue with the last run of the Spectrum HO heavy weight passenger car trucks metal crumbling apart?  These are for the last run they made with light bulbs and separately apply hand rails. 

Not sure if there are any replacements available.   This also makes to very Leary of purchasing any of the new runs.  Will they also fall apart after 10 years.

Walthers has many 36 inch wheels if you can't get them from the Bach Man.

Thanks for the replay.  I replaced one set of trucks with a Walthers heavy weight set. It was not a not a simple task.  The replacements trucks are not available from the Bachmann parts shops.

I first noticed cracks in the trucks between the wheels.  Then a car would go though a curve or turnout and truck will just break apart.

It's the die-cast metal parts of the trucks that are deteriorating and becoming brittle .  This is happening on both the 6 wheel and the 4 wheel trucks.
