Yeah I definitely overtighten and also check them after a while, never had a wheel come off. Happened to my dad in the 70s though, got passed by his own tire.

Save money on a torque wrench by just adding jb weld to the threads before you tighten

Almost had a wheel fall off on me years ago. Sounded like a helicopter hovering right over my car. Since then I check twice after I change a tire(s) with the car on the ground,take it for a 10 minute drive, check again. Check the next day,ns then about a week later. Don't really pay attention to the kms I've driven though.

Point is...you don't need a torque wrench calibrated to super tight tolerances such as a Snap-on (or whomever makes them). You want consistency across the criss-cross or star pattern which something like a HF will be more than happy to provide at these torque levels. Now, if stranded changing a spare. Stand on the lug wrench and hear the creeeek. Move on.

honda whisperer posted:Get a torque wrench. All of you. Lug nuts HOLD YOUR WHEELS ON. What I do with those nuts is not your business! The other thing to consider is when overshooting the torque spec it stresses the lug stud, hub, nut, wheel, etc. I kept three torque wrenches on board while on the road. Any time I rotated the tires on the vehicle it got torqued to spec and rechecked at 50 and then 150 miles. Outside of that? Most of the time I don't bother. My hands are pretty well calibrated. Other areas for whipping out the torque wrench is flywheel bolts, steering, suspension work, and brakes. HF wrenches are ok enough for the home gamer. It's more important to develop good tool care and unwind its spring, don't leave it out in the rain, use it as a hammer or prybar, etc. Know that there's a range their good at. A 150ft-lb rated wrench is gonna be most accurate between 40 and 130ish ft-lb so don't use it for torquing down m6 coolant pump bolts. Get the inch pound jobbie for that.

I don't use a torque wrench and even if I got one I doubt I would use it on lug nuts, I'm used to go by feel there and will likely continue that practice. I'm interested in torque wrench for other stuff where I don't have a feel developed for how hard I ought to tighten. My future also likely holds other projects where it becomes even more important.

I came into this thread to ask why my brakes might be shaking only once they're hot (I.e., they're fine for a while, but if you drive 30 miles in traffic, they'll shake bad as you get off the freeway), but I'm going to go make sure my lug nuts are tight before I actually ask. I'm pretty sure they are, but ya know, feels like a sign.

I always just get my wheels snug, "rent" the torque wrench from autozone (I believe it's free), torque them in the parking lot, return the wrench, and continue on my merry way. To be completely forthcoming, the first couple of times I did that, I had accidentally over-torqued by hand. I'm still kicking though.

I have a 99 Camry with about 94000 miles. Intermittently the transmission will hesitate on upshifts. When it does this, it may also shudder a bit while driving a constant speed. Fluid is fine, but maybe a bit overfilled. What should be my first thing other than that to start looking at?

I didn't have a problem with torquing by feel when most torque specs were 85-90 ft/lbs. Now that it's 120 for my truck, I'm older and weaker, and don't tighten two or three hundred lug nuts a week, I use a torque wrench. The HF one that stays in my truck is just as accurate as the Snap-On at home for this purpose.

Warped rotors are exceedingly rare, I would lean more towards pad deposits. Go find a long empty stretch of road, get up to 60mph then brake HARD down to 5-10mph immediately accelerate back up to 60mph and do it again. Do this several times, say 5-6 to get a lot of heat into the brakes, then just cruise for a while with as little braking as possible to let things cool back down. This will clean the pad and rotor surface and is generally referred to as bedding in brakes which is recommended when you put new pads on old rotors.

My Vibe (toyota drivetrain, probably a very similar 4 speed auto) had similar symptoms albeit more mild at similar mileage, and a fluid change fixed it right up.

I will put a vote in for using a torque wrench for lug nuts too. I dont care how well you think you can do it without, the torque wrench will almost certainly be more accurate. Under- and over- tightening pose risks, so best to be as close as possible. Just my two cents though.

honda whisperer posted:Get a torque wrench. All of you. Lug nuts HOLD YOUR WHEELS ON. I have four of them. I use them on: Axle nuts that set bearing preload Flywheel bolts Ring gear bolts Pressure plate bolts Bearing cap bolts Head bolts Basically anything that's very infrequently changed or checked and is super critical for bearing preload or similar reasons. But lug nuts on a 35 year old poo poo box on studs that may have been used 20 times and the actual preload from those gummy old threads at spec torque may be a tenth what they intended? Nah. I'll go with my gut based on how much force it took to spin it down most of the way before it even contacted the wheel. VelociBacon posted:Greasing the bolts would wildly change the appropriate torque spec wouldn't it? Yes. It also varies by like 25% from plain steel to black oxide to zinc plated and all of those are available on the market depending on whether it's a OEM, new, or different company new part, so good luck picking what torque you're going to use I guess, people.

I'm usually one with the AI hive mind but I guess not here. I've caught failing wheel studs maybe 5 times in my life by always using a torque wrench. Star pattern then around in a circle. One moves significantly again. Give it another.... Nope still turning. Would have passed a gud n tite. It doesn't take that much longer. A lifetime of torquing lug nuts will never add up to waiting for a single tow truck. For re-checking they're tight after your 5-7 year tire change? Quick check with the trunks wrench is fine. For the AI goons that are wrenching constantly and already own a torque wrench? You're wrong and should feel bad.

Overtightening is not always safe. I had an issue with thread loosening after durability and the fix was to decrease the target tightening torque. Of course, this is in an application with some thermal cycling but point is, sometimes things can be counterintuitive and potentially get you into trouble. Also, it's always safe until the day it isn't. If the result of "it isn't" is "drat it I got a paper cut" then fine, keep doing that. If the result of "it isn't" is "my wheel fell off at 80 mph down a highway" then that's probably not what you want to gamble on. It's not about "under what conditions could I potentially undertoque my lug nuts and be safe" it's more like "does doing this raise my chances of the wheel falling off from basically zero (it's never zero, is it.. ) to not-basically-zero"? And the answer is yes. And do you want to find out just how many miles you might have to drive with those to run into a problem? No. You absolutely do not.

I would say that the vast majority of people who have ever changed a wheel never owned or used a torque wrench, and wheels dont fly off as often as the thread seems to imply.

I rarely torque my wheels. I do on my Cayenne, but Porsches are weird German beasts that prefer a little pampering - or they may bite. In 45-years, I have had one wheel nearly fall off (on the Econoline; I caught it with 2-loose lug nuts, the rest were already gone) but that was due to my lack of familiarity with the American Racing mag wheels it came with; I had gotten rid of the weird 12-point narrow-head lugs for standard chromed hex lugs, and this was how I discovered that the wheel center hub casting was interfering with the barrel of my socket / impact wrench so they sounded tight when they weren't. I had to buy a set of thin-walled sockets. Also carefully ground down the five lobes on the aluminum center caps to insure they weren't interfering (the center-cap lobes stuck out further that the casting of the wheel itself). I'm old. Maybe don't be me.

The fuckin dealership actually did this during an oil change and then tried to say it was already like that and that I must have done it when I tried to change it myself, even though no one else had changed that cars oil but them. That's what spurred me changing my own oil for the first time and never bringing the car back to the dealership again unless it's to sell it or get a recall fixed for free. Fuckin scumbags.
