OT torque multipliers Options

[JFG]

I need a liitle more torque than my wrench has on it's scale so that i can correctly tighten the rear axle nuts.

I've been looking at torque multipliers but as i've never seen one before i don't know what they're like.

I read the descriptions and they talk about releasing nuts and how easy it can be but they don't all say about tightening. It may be obvious to those who have used them but are there versions that only undo and others that only tighten or do both?

Rear axle nuts don't need to be torqued. I pop then on and off all the time as it's my preferred method of removing the CV. I use a breaker bar and a 3ft cheater bar for removal and then for install I stand on the breaker bar and give it a couple bounces. ~250lbs of force. Or I use my cheater and get it good and tight.
