The single most expensive part on a CCKW?

[pfarber]

One of my TM10's has a price list. The prices that are listed (some are POA) are June 43 TM10 parts book (the last one before the information vanishes and the SNLs take over:

GM 2170974 FRONT AXLE ASSY. (6-3/6:1 ratio) (Timken-Wisc. Div. No. F-30-B-28-H-X33) (With Razeepa joints) NEW $505

Some other prices

SN-3230 GMC 270 motor NEW $282
Fire Extinguisher GM 2176169 $9.32

Seems that the most expensive parts on a CCKW are the axles, but a wide margin.

Amazing that the axle is more expensive than the engine !

Rzeppa CV joints seem to be much more complex assemblies to machine than the Bendix. The Bendix axle was about $100 cheaper... the parts are basically the same until you get into the hubs and CV joints proper.. then the complexity of the Rzeppa joints are clear. The G503s also had this this issue... two types of CV joints... Rzeppa and Bendix, Bendix was also much cheaper.

Add to that the banjo casting itself.. that alone was probably a big chunk of change in 1942/3.
