5/5 steps released · 2 linked sources · about 25 minutes.

- Check adapter engagement, rubber contact and sweep clearance before driving.
FASTENERS & TIGHTENING
Check the hardware before you start
No separate verified fastener map is published for this guide. This does not mean no fasteners are involved. Follow the released steps and their cited specifications; if a required tightening or replacement rule is missing, stop and verify it.
How WrenchGuide treats fastener information
Material, reuse policy and tightening method are separate facts. Torque plus angle alone does not establish that a fastener is torque-to-yield or single-use. WrenchGuide will not invent a torque value or replacement rule.
