Half the time I TQ them before AutoX, they are less than 140ft/lbs.

Yes, that's why when doing testing we measure and record all torque values, instillation torque and residual torque (some engineers wanted Torque to Tighten and some wanted Torque to Loosen but we always used an ST wrench). It's very time consuming to measure all the torque values at the start of a test, middle of a test, and end of test. And by all, I mean all. That self taping screw holding trim pieces to the dash/door panel/anything has a torque value. And most are over tightened when serviced at the dealership.

The 2019 manual is definitely updated to 140 lb ft. To bad my torque wrench is suppose to go to 150 but it will only get to 129#. So I borrowed my neighbors that is suppose to got o 150# also. Turns out his only goes to 130#. Lesson here is that two different brands of torque wrenches that are suppose to be 150# max won't reach that number, buy a higher rated wrench. Just ordered a torque wrench that will go from 25#-250#. Keep wrenching friends.

...and the bump from DOWNTOWN!!!


Had to search to find a 2018 torque thread

Glad this came back from the depths because I definitely just assumed it was 100. Oh well, the wheels didn't fall off.

Also, whatever lube tech put them on last definitely didn't do it to spec. Some of them I had to sit there for a minute with my Ryobi impact to get them off, others were barely more than hand tight.

When I did my brake fluid flush, torquing the wheels was the most difficult part...but it is at 140!

I have not independently verified this, but conventional wisdom is that torque wrenches are most accurate toward the center of their ranges. So, the one you ordered should be good.

If you don't mind sharing, what did you order, and what do others recommend for a torque wrench where 140 is about in the middle? I still need to get one.

Though I've not invested in an "Icon" item yet, Harbor Frieght's Icon line is supposed to be rather on-point :

I own some HF things, but I am not sure I want to trust anything from them requiring precision. Maybe those are fine, but I am a little leery of them. My current tq wrenches are Matco and Bluepoint.

Yeah, I definitely wouldn't trust a torque wrench from Harbor Freight... lol

This makes me wonder, how critical is it that lug nuts are to spec. Mainly how much variance before you start to see an issue. I mean, it seems like most cars lug nut specs are measured in uggas and/or duggas.

Opinion: For most cars driven routinely, I don't think it is very important beyond "tight enough". We've all had to change flat tires, and nobody uses a tq wrench when doing that.

However, when you are talking about a vehicle that can go around 180 mph, I start to want to be sure that things are attached according to specification, since the forces involved at high speeds are greater, and if anything goes wrong if could be very ugly. So, a little "click-click" would give me some peace of mind. Not that I drive terribly fast on public roads, but still...

My theory is that impact wrenches aren't the most accurate things, at least not the cheap one I have, and a torque wrench is just as easy to use as anything else, so why not use one.

I agree. We're not trying to beat the flat rate here.

I do like air tools for breaking free really stubborn fasteners and for running things in or out, but I like to do final tightening with a tq wrench. A lot of this comes from my background of working on motorcycles. Motorcycles tend to be a lot more "spec sensitive" than cars and trucks so you have to be more careful working on them, but the desire to do precision work carries over for me.

That’s crazy, I’ve done a bunch of track days torquing my wheels to 100lbs. Never had a problem, one track I hit 142 Mph. I checked after each session, the wheels never lost torque. I’ve raced cars for years, 140 is really tight, I never heard of torque specs that high
