This is a set of "banjo" or "corporation" axles for the Tamiya CCKW 2-1/2 ton truck kit. (#35-218) They replace the one-piece Timken "split axle" drivetrain, and add the option to pose the front wheels at an angle as if steering. You will need to cut off all the prop shafts and add them to the new axles after gluing the axles in place on the springs. The Tamiya wheels should be a simple press-fit on these new axles. Note that there is a new transfer case to replace the kit part.
What do you get?
3 axles (front, middle, rear)
2 steering hubs (for front axle)
1 steering tierod
1 transfer box with brackets
1 pillowblock (sits on middle axle, connects rear axle prop shaft to main prop shaft)
2 link bars (connect rear axles to frame crossmember to limit sideways movement)
1 transverse link bar for rear bogie
