Impact driver what size do I need?

[edcartwright]

Hi all,

My sons car needs a pair of shock absorbers replacing and I'm thinking of getting an impact driver to aid removal. However I have no idea what size (NM) impact driver to buy. Any ideas, I had thought 240NM, but after watching some Youtube videos, I think I may need higher?

Thanks for any advise.

That's not going to require anything with huge torque. 'Going big' is good in the sense that having extra power is less likely to cause you issues than having too little. It does tend to make the tool more bulky however, which can mean that you are unable to fit it in the area needed to access the fasteners (very relevant to working in a wheel well).

I would go for something like this:-

Plenty of torque for anything you're likely to encounter doing a shock absorber and very compact. Also comes with two big batteries which are well worth having.

i would go for the most powerful one you can afford.

I did what you did and went for the one i thought would be the power i would need. I ended up buying the biggest makita they do. I found when doing suspension work, some of the nuts get so corroded that even the big one struggles sometimes, but it's better to have too much power than not enough.

the other benefit is you can get wheel nuts off super easy, which isn't always the case with the smaller impacts.
