Harbor Freight Cordless Impact Wrench

Is the Harbor Freight cordless 19.2v impact wrench strong enough to take strut bolts off with and then reinstall?

What about for taking the top nut off the strut as well?


TIA,

Brian

Do they give a torque rating on the thing, bigb? I can vouch for the Harbor Freight el cheapo corded electric impact doing all that, but having a battery one would be a nice thing.

If it's 200 ft/lbs, Brian, that should be enough. How much do that want for it? I've got a suspension install coming up this spring.

Peace,
Mark

200 oughta do it. Just about anything will take off the top nut - that just takes patience and penetrating oil (and either the impact wrench or some inventive four-letter words), but the lower strut bolts oughta come out with that. I saw Kevin of Comprent use a Snapon battery impact this weekend to pull off the single nut on the wheels of an S2 and I'm pretty sure those had been taken down to 140. The Snapon was no monster, and for the limited use you're going to give it, I wouldn't worry about wear. BUT - just imo, why drop $50 on one of those when for our use most of the time a cord and a $15 or $19 special will do just fine?

I don't see a 19.2v listed on their site. Where are you getting this from?

I've had one for a year or so and no problems breaking lug nuts loose (until the battery starts to lose juice). Also used it when changing the stuts in my SE-R. Works great if you have the rental Pep Advanced Zone 2-piece manual spring compressor, too.

I've been using my HF cordless impact gun for 2 years and I have no complaints. I have used my gun to undo the lower 2 strut bolts before, but I've never used it for the top strut nut.

I bought two of them as it was $10 more than buying an extra battery.


I DOES NOT WORK WELL. Only ~80ft/lbs. And it tightens stronger more than it loosens.

I heard that the other, older style is the one to get. After I get my money back on these two I will try it. This is supposidly the good version.....



that has been discontinued.

You're saying specifically that the 19.v model is not good? This one here?

Chris,

That is the one most everyone uses down here that is not either SnapOn or Matco... it works very well at pulling lugnuts at the very least.

Thanks B, the whole reason for buying it is taking for tire swaps at the track. I already have my HF Earthquake at home. Hell, I only torque my lugs to 90ft/lb so this should be overkill, and since I use my torque wrench for final tightening, I'm not looking for allot from this.

I'd still like to hear fairgentleman z's opinion.

Yes, I ordered 2 of those 19.2V charged both batteries and tried both impact wrenchs. I like to have my lugs ~ 100 ft/lbs. It could not break them free. So I broke the lugs free, and then tightened them with the cordless impacts, it put them on tight, but then it didn't have enough torque to break them free again.

Another member off of improvedtouring.com measured the torque around 80 ft/lbs.

IMO an impact wrench should be able to break away lugs. Break away torque should be higher than tightening torque. This wrench does neither.
Tightening I'll always double check by hand.

You can always try it out for yourself. You have 90 days from the date that you RECEIVED them. I told them it did not work as advertised.
