LS400/430 steering wheel motors

This may have been mentioned before and I've missed it.  I've always wondered if these motors can be rebuilt, now I see someone on eBay doing just that.  So I'm wondering what's involved, and if it can be done with some basic info.

Do you have the eBay link Phil?

I always thought that these were AC synchronous motors similar to the ones used in domestic microwave ovens for the turntable which consist of a cylindrical ferrite magnetic core, a coil winding, various reduction gears and an output shaft gear.

The ECU has a warning sticker attached warning of high internal voltages which would suggest the voltage is higher than the normal 12VDC system so may contain an Inverter.

The core apparently breaks up resulting in a mechanically seized motor but I would be happy to investigate this further should someone wish to donate a defective unit I can reverse engineer.
