I show how to disassemble and assemble a Shimano freehub body. I clean, lube and install new bearings into the freehub. I basically overhaul/rebuild the freehub. Generally, freehubs are not meant to be taken apart like this. The common thing is to just replace them, or to flush them and lube them like I do in this video:
This might be useful if you are having a hard time finding a replacement freehub body for your particular bike wheel. They are not too hard to take apart and overhaul. They might still have more life in them. And it’s kind of fun anyway.
Here is a video for how to make the freehub body disassembly tool I used in the video:

Weber State University – Automotive Technology Department – Transmission Lab – Measuring transaxle front differential side gear backlash on a Toyota A245E transaxle. Too little or too much backlash can cause noise while turning corners. Backlash is typically adjusted with shims behind the differential side gears. This procedure is generic and will work for most transaxles as well as front and rear axles. It helps to have the axle shaft installed to hold the side gear centered in the differential case.
This video helps demonstrate part of NATEF Tasks:
A2.C.17. ” Inspect, measure, repair, adjust or replace transaxle final drive components.”, a priority 2 task.
A3.E.1.10 ” Disassemble, inspect, measure, and adjust or replace differential pinion gears (spiders), shaft, side gears, side bearings, thrust washers, and case.”, a priority 2 task.
