I want a complete guide for designing gauges and fixture for a part with tolerances.

This could be anything from designing interplanetary spaceships to a shut off valve in a water heater. Care to expand a bit?

I want to design it for front hub

Front hub is a reference to wheel bearings, so if you could be a lot more specific maybe we can help. The more information the better. A drawing picture would be great.

Most fixtures for hub measurements are available today. I have used them for rotor and hub alignment on front ends. Run out gauges are commonly available and use magnets to hold them on.
