Will this work on my vehicle's specific hub design?

Universal pullers work on most front hubs, but jaw adjustment range varies by vehicle. Test-fit the jaws on your hub bore before starting the pull — if the jaws don't grip firmly across the diameter, you may need a specialized puller for that application.

Do I need to remove the brake assembly first?

Depends on your vehicle's rotor and caliper layout. Some platforms let you work around the rotor; others require caliper removal for safe jaw clearance. Check your service manual for the correct disassembly order — pulling with obstructed access can damage components.

Can I use this with an impact wrench or do I need manual strikes?

Slide hammer extraction is the intended method — controlled, measured strikes that pull gradually. Impact tools can shock-load the hub and bearing, which defeats the purpose of a three-jaw puller. Stick with hand strikes using the hammer weight.
