If it is a solid sleeve then yes you can tighted to torque. If a crush sleeve, then no as you chance crushing the sleeve more.
Mine was a crush sleeve.
What I did, was mark the nut and pinion shaft. Then counted the number of rotations for the nut to come off. Then put nut back on that many rotations.
NOt the best way to do it, but I knew i'd be back into it in a couple months to regear.
Maybe someone will have better idea.
