Mark the diameters that enter a mating bore and state whether the joint must slide, rotate or hold its position. Keep a fit requirement separate from a non-functional relief diameter.
A stepped shaft can be the correct size at each section and still need an alignment requirement. Identify the datum axis, the relevant surfaces and the agreed method for checking runout or straightness.
Show shoulder locations, groove widths and end details clearly. Include the required edge condition where a pin enters another component, and flag any surface that must remain free of burrs.
BUILD A USEFUL HANDOVER
Shortlist the closest examples and attach your own current drawing. Your review should cover geometry, exact material grade, finish, quantities and acceptance requirements.
