Slide one wheel/axle assembly into a wheel pant, and install the wheel assembly on the landing gear leg.   
Tighten the locknut as shown to secure the assembly onto the gear leg. Repeat for other side. 

Attach the gear to the fuselage with short 3mm screws, use loctite. Install gear cover plate as shown.    We have used clear 
tape in this photo, but thick CA or epoxy glue works well.
