Your method sounds suitable but I copied this for you for specific instructions just in case your bored and want to check end-play!!
1. Release internal bolt of clamping nut, and tighten clamping nut while simultaneously turning the hub until hub can only just be turned. Loosen clamping nut approximately 1/3 turn and relieve tension by striking stub axle with a plastic mallet.
2. Position a suitable dial indicator onto front hub assembly.
3. Check endplay by pulling and pushing on the flange. Turn wheel hub several times before each measurement. End-play obtained should be 0.00039-0.00078 inch (0.01-0.02mm).
