Put 2 wheelbolts back in then use a pry bar against them and the road to lock the wheel in place. Then you can use as much force as you can.
Ha, I did that first! Now I have a bent pry-bar, and a bent wheel bolt. I was jumping on a 3/4" breaker bar, so around 700NM I estimate.

With a long bar, most of the sharp force that breaks the join is taken up by the suspension....

Honestly with an impact gun, I don’t even bother to unstake them - just whizz them off.

It's a beast. The only problem with the 18v batteries is with the 2ah ones that are a bit weak. The others are fine.

If you don't have an impact driver, shove a screwdriver down in the cooling vanes of the brake disc so it rests against the caliper then get your breaker bar and find a long length of pipe or scaffold pole or similar so your breaker is 1.5m long or so and lean on it. Easy.

When you say weak do you mean the torque output is affected? All my batteries are this 2Ah type. I thought they would just last less time? Now I'm thinking I should get a higher capacity battery.

I started to do that , but the caliper frame started to flex alarmingly, and of course the screwdriver bent.

I did that once too, good to see i'm not alone. I had quite a meaty screwdriver when I did that and a breaker bar the length indicated too and it came undone OK. I might have used some heat on it as well, I can't remember.

I think it reflects the run time of tools. However, I would think a battery with a higher Ah rating would be able to continue with the peak power for longer over a lower Ah battery, as well as lasting longer in general too. Generally though modern batteries tend to just quit and don't give much warning at all so what I said may not be the case.

Done lots like that and never had an issue, even with the tight one's that need 2000Nm to crack them. Not sure how you managed that.

The 2 Ah batteries cut out very fast, and do generate less torque. It’s not just on this impact gun - they do it on an SDS drill when I’m using a 2 foot long bit.

If you want it at its best, get a 54v FlexVolt battery - 6Ah is fine. But a big 18v battery will do the job.

This is the onlt one I can get today:


I may try my 2Ah batteries first, and if they are no good, I ccan always pop back to the shop. The flexVolt batteries are quite expensive, and on 3 day lead time.

Try your 2s. It may be fine. But if the 2s aren't, I wouldn't drop more money on a 3..... go bigger.

I just checked they are not even 2, they are 1.5Ah!. I needed four to drill a 5" hole through the wall of my house. I do not expect to do anything like that again though.
PS accidentally bought a 4Ah .

Well, I didn't need the big battery after all. I did have to jam a screwdriver into the brake disk, and put the deWalt on max for about 20 seconds, but I used it to undo both the hub nuts and all the wheel nuts, and there seemed plenty of go left in my 3 year old 1.5Ah battery. Screwfix let me down in the end, so I ended up buying the impact gun from Toolstation, for a little bit more money. I tried a 10mm hex impact socket on the 156 suspension pinch bolt, and it just rounded the inside of the cap head pretty quickly, which I sort of expected. I already ordered new ones a few days ago.

I was just quickly jotting down the torque values for the front suspension bits, when I came the hub-nut. It says to torque is close to 71Nm, then turn it a further 62 degress checking the torque stays between 2000 and 3600Nm ! So basically as tight as you can possibly make it? This seems way too much, is this a mistake?

There’s no point in overthinking this stuff. We only have 2 settings:

FT - when you really put your pack into tightening something with a conventional socket wrench. Or the DeWalt on 3 for a few seconds.

VFT - as above, but with a scaff pole. Or the DeWalt on 3 for about 10 seconds,
