I'm thinking about getting a torque wrench and was wondering which size drive will get me the most use. Any suggestions?

depends on what size most of your sockets are?I would say 3/8th would get more use and there are always the adaptors you can use to size up to 1/2in

Most of my sockets are 3/8". My immediate concern is troubleshooting a shudder coming out of my front wheels when I brake. ehoff121 suggested checking the torque in my front lug nuts before moving to the rotors. So now I want to know whether its better to torque 76 ft lbs using a 1/2" drive or a 3/8" drive. How much can a 3/8" drive take? If a 1/2" is better for that job, then I think I can get a 1/2" to 3/8" converter to accomodate the majority of my sockets. What do you think?

The progress bar required 150# torque of the bolts, which you will only find in a 1/2" torque wrench. The 1/2 to 3/8' adapters work fine. If you have only one, I agree that it should be 1/2".

The local parts guy let me take a few out to the car to try them out, though.

If you happen to remember the socket size (english or metric?), great. If not, no big deal. Thanks again for the tip on the lug nut torque possibly causing the front wheel shudder. I'll let you know what happens with it.

If I recall correctly, OEM lugnuts are 3/4" and any aftermarket tuner lugs are likely 19mm. Or I have it reversed I don't know.

It's a 21mm deep socket (hex pattern inside).I have the factory alloy wheels and an AWD, so you may want to double check that you have the same lug size.Good luck!

I could be wrong but the 1/2" drive is normally in ft.lbs and the 3/8" drive is in.lbs so it depends on the application.. I think for lugs you's want the 1/2".. and then size down for other..Just to note, Canadian Tire Maximum Line is on sale 50% off torque wrenchs today ($124 on sale for $59). Picked one up today.

Ah the useless stuff you can buy at Princess Auto!!!I have 1/2" drive Torque wrench. And all the tools I buy are 1/2". I never saw the point of buying a set with 1/4", 3/8", and 1/2" drive when you can buy it all 1 size. If you need something smaller, grab a wrench!

Believe it or not I use my 1/4" drive sockets and wratchet more than any of my others. I just find them more user friendly and they get in to places that a normal, say 3/8",10mm socket will simply because they have thinner side walls.

I first had a 3/8" which can do 0 to 100 ft/lbs but when I installed a rear sway bar I had to buy another 1/2" wrench that went up to 250 ft/lbs. It depends on what you need it for at the moment. Id say get the 3/8" drive wrench that goes up to 100 ft/lbs because it could be used on a lot more stuff. There aren't too many times you'll need to torque stuff down over 100 or 150 ft/lbs. Get one of each if you can! the bummer about torque wrenches is they're expensive for the nice brand names like snap-on but, sometimes cheaper wrenches will do fine. I've been wanting to have my wrenches tested for accuracy but, they do come with signed certificates showing they where tested at the time of manufacture. And the wrenches are supposed to be able to be used several times before needing to be calibrated.. Ohhh and make sure you read the instruction before turning or twisting any dials or adjusters on the torque wrench if your getting a clicker type.. I had a new wrench and I loosened the adjuster below the lowest setting. I found out your not supposed to do that after reading the directions..oopps!

We need a "Tool" sub forum.I've been 'renchin' for 40+ years.There is probably someone out there that has a trick that I never thought of or a tool that is more useful.With the Vibe being a more "younger" generation car, "old farts in training" like me could still be useful.
