Which Impact Wrench and Jack?
Been collecting some tools to work on my E93, and looking for a good a impact wrench (I think I need 100ft lbs of torque), and a jack (low profile, already have a jack adaptor).
Would the craftsman C3 impact wrench be a good choice, or harbor freight have any good ones? Not trying to break the bank. Will be using this jack to get to tpms transmitter, oil changes, etc. |

What are you going to use the impact wrench for? If it's only for the jobs you've listed I would skip it all together.
Generally I dont recommend using them to apply your final torque, I'd suggest a proper torque wrench for this. That said, I don't think 100 ft/lbs will get much done for you. I have a corded electric impact wrench (1/2" drive) that puts out 270 ft/lbs and there have been times that it doesn't have enough power for the job. This won't be available to you (not under the same brand anyways), but it'll give you an idea (price is in Canadian dollars). I think I paid around $75 when it was on sale. Truthfully, I diy all my work, and I only use this thing once a year or less. I don't even use of for tire changes. https://m.canadiantire.ca/#/products...182&quantity=1 I know this doesn't help you pick a wrench, but maybe it'll save you the cost of buying a tool that may not be useful. |

I use a Dewalt electric (gift years ago) mostly because at the time I had no compressor and really for simple jobs the electric is handier then charging up a pancake or such. I don't have a full time shop with constant air supply running.
Other then suspension and other bigger jobs, I don't have any need for air tools. Its perfect for lug nuts of which I do a lot since I swap multiple sets of wheels each year with dedicated snows for all my cars. Most of the time its fine, but if a shop apes the lugs I still need to bring out a breaker bar to crack the lugs loose. If I put them on with proper torquing, the gun spins them off with ease. Jacks to me are where you should not skimp. I have been using a low profile AC hydraulics for a long time. - b |

Do you think its better to get a torque wrench or impact wrench? Seems like a impact one would cost more, but a torque one would require more effort?

A torque wrench will have a handle the right length for the target torque range. You should never trust an impact to set a torque value, it is a recipe for disaster. These tools are complementary, not replacement for one another.

Then why do the people at tire shops use them, etc? Is it always better to use torque wrench?

Personally, I like the really low profile jack from HFT: http://www.harborfreight.com/automot...ump-68050.html
Their electric impact wrench is now on sale for $39: http://www.harborfreight.com/12-in-H...ODA1MiJ9%0D%0A

Get snap-on. I got it, and its really good 750fp of torque i belive. Its battery so no need air compressor. Plus i am a mechanic and about 90% of my tools are snap-on. The rest is mac tools or matco tools. With snap-on i never had any problems.

You can use the impact to tighten it, but you'll either way overtighten it or not get it tight enough. They use them at the tire shop because it's fast...they should be checking each lug with the torque wrench afterwards. There's really no need for an impact other than it saving a little bit of time...there are some suspension bolts and crankshaft pulley bolts and other things that you really need the power of the impact for, but for the wheels you can loosen them with a breaker bar. The only advantage of the impact is that it saves time, which doesn't make any difference if you're not doing it all day in a shop. |

Glad you brought this up, just saw its on saw today for $11.99. I just need the 1/2 one right, or should I get a 3/8 one too?

You would be fine with the 1/2. You can always get the other later if/when needed.

An impact wrench is also very useful for removing rust/corrosion welded nuts/bolts. The impact hits break away the rust bond. A breaker bar can break the bolt before breaking the rust bond, don't ask me how I know. |

The 1/2" is normally the first one people buy when building up their tool collection and you can use a 1/2-3/8 adapter socket to use smaller sockets with it. |
