Good video as a retired aircraft mechanical engineer one point you missed on is the surface face of the rim and hub, both need to be clean and free from chipped paint, dirt etc Back in early 2000 their was a time when a public bus company had a lot of wheels coming loose and a few occasions they came off, all nuts correctly torqued but with paint chipping on the both faces the nuts become loose. Recommend anyone changing a wheel to wipe both surfaces the hub and rim both sides especially if Dusty, sandy, muddy areas

Yeah, I can attest to the excessive robustness of the wheel studs. From when I was about 13 years old working on cars I used to lubricate my wheel studs when reassembling and I NEVER reduced the torque value I applied until I went to college (majored in Electrical Engineering - Minored in Mechanical) and better understood the dynamics of a bolted joint. I NEVER broke a wheel stud even with a lubricated stud at full torque. Now I do 80% and fight the urge to do more (it never feels like enough). I've also never had a wheel nut loosen up in my 45 years of working cars. So I can attest that 80% isn't a bad number.

50 years of driving in the North American rust belt has given me appreciation for anti-seize. Make sure the wheel to hub mating surfaces are clean, apply a thin film of your favorite flavor of anti-seize to the surfaces and threads. You won’t regret it next time you need to remove the wheels for maintenance or roadside repair. Nice hat John. Dave in CLE.

Never used a Torque wrench on wheelnuts and don't own any type of rattlegun, never use neversieze. Just tighten them till the spider gets stiff, give the wheel a few belts with a rubber mallet(or something !) give the nut a half to quarter turn. A new to you motor ? before undoing wheel nuts, douse the wheel nuts with whatever you have, they'll come off !

I was a boilermaker in another life and the rule of thumb for torque on bolted connections was "Tighen 'er a much as you can, then 2 more turns, and she'll never leak." However, this is probably a bad idea for your alloy car wheels. Mr. Cadogan is absolutely correct that when stud manufactures say "dry connection" it means a coating of light oil (not actually dry). A SMALL amount of copper coat, or even better, a nickel based lubricant isn't a bad idea and multiplying by 0.7 is also a good approximation of the reduction of the specified torque that should be applied. I have a boat trailer that regularly gets dipped into the salty water. Because of the way the brakes are designed, the wheels are held on with screws, not studs and nuts. I put a small amount of non-hardening gasket sealer on the threads before installing and never had a issue with getting the wheels off when I need to.

@peglor 2 ай бұрын

One feature on wheel nuts that is essential but not understood is the purpose of conical shape of the back of the nut which matches the hole in the wheel. This is to counter a behaviour called thread precession, which causes bolts that see a circular loading in shear to work loose if the load spins in the wrong direction. This was initially remedied by having left hand threads on one side of the car (In the era of wire spoke wheels and hammer off central wheel nuts), and can still be found on bicycle pedals, which are left hand threaded on the left side.

To lube or not to lube, that is the question. Being aware of the differences in torque required by having read a pamphlet by Never Seez back in 1965, I always check to see what is required. Never Seez stated that you were to lower your torque values by 40% when using their product. In the case of my standard motor vehicles, the studs are supposed to be clean and dry. My Alcoa Budd wheels on my motor home, based on a bus chassis, require lubrication at certain places before torquing to 500 foot pounds. Since I do not have a 600 foot pound torque wrench I bought a torque multiplier so that I could use my 250 foot pound torque wrench. An inconvenient feature of the studs on the motor home is that one side is left hand thread.

Great video as always. Next items to buy is a torque wrench and some copper grease. When my rims won’t come off, I loosen the nuts 1-1,5 turns and drive car forward as well as in reverse and hit the bakes in both directions. The click heard tells me the rim are now ready to come off.

I've used Copper coat for the last 40 years. It's been a tremendous help re fasteners exposed to the elements. Like wheel nut as John points out. The nuts don't unwind and when you do unwind them with force they don't bind. Yet they do hold when left so long as they are torqued up right.

@gerardwood4059 2 ай бұрын

Hitting the breaker bar with a hammer works really well. Word of warning, the shock wave that you put into the breaker bar, that helps undo the wheel nut, also goes into your hand and arm at the other end of the breaker bar. So do wrap a thick cloth or something around it to absorb the shock. Alternatively, do not push hard on the breaker bar, or hit it less hard with the hammer. Start gently and work up to more force, until the nut comes undone! Remember keep all parts of your body out of the way, nuts, especially hydraulic, have a tendency to suddenly become loose, you do not want to hit yourself with the hammer.

I completely agree with you. I'm not as good about removing torque after I use lubrication but I do use less and I've never had one come lose (or break from over torque). On a real-life experience, we bought a used Ford F150 pickup and needed to remove the wheels to replace brake components. I got out my normal 1/2" drive rachet and was unable to remove a single nut. So I got out a 2 foot breaker bar and was only able to remove 1 nut on each wheel. 😐 My assumption was that someone used a very large impact wrench to put them on, which was more than irritating. I ended up buying a large impact wrench and ultimately got all but one nut off which I finally took it to a tire shop and they used a torch to heat it enough to get it off. Did I say grrrr... oh I did. So the interesting part of this (to me) was that I learned it's not the friction between the nut threads and bolt (stud) threads that is the issue in this particular application. It's from the friction between the nut face and the wheel. The tire shop said especially on these F150 pickups they see this frequently where the nuts are torqued to spec but later become much harder to remove. The answer I'm told is to put a small amount of antiseize on the face of the nut. I'm only about 3yrs into ownership of this F150 so I can't swear this is "the" answer but so far so good. Long story, sorry, but maybe it is helpful to someone.

This is why the hand tight and angle method is more accurate, hand tight just means for the nut or bolt head to touch the surface and then an angle ( depends on pitch of thread ) to enure the correct amount of pre-load ( stretch of the stud ). Torque is quoted for a dry thread, once lubricated the torque is 25 to 30% less... Get one of those telescopic wheel wrenches - use the collapsed length to tighten nuts and use the extended length to slacken..

This was a really great episode. Been doing a lot of rotor and break pad changing at home starting easy just doing 2 sets of pads then doing all 8 rotors and 8 sets of pads on our family cars. Have cleaned with acetone on general but also break cleaner spray (mechanic strength - smells like ammonia) and haven't lubed the nuts, just scrubbed down with wire brush - I haven't had this much satisfaction in years! Got Brembo pads all around, DBA rotors on my forester and Brembo on wife's Jazz. I noticed that my local premium branded Japanese tyre centre over tightens the occasional nut and over inflates the tyres. I bought a compressor to fix the problem. I love my two torque wrenches, they give me piece of mind and a sense of satisfaction knowing there is a right way only to use tools. I went to school with Jezza - he hasn't changed. Plays a wicked electric start into a Hotrodded Marshall amp! Question: the Honda engineers seem to have put white nut lock on the bottom bolts for the caliper pins... do I have to reapply these or would I be better just changing out the bolts?

Thanks John. I’ve been using copper slip for years now without issue, although have not used the torque correction, may start using that. The point about smearing this onto the hub/wheel before putting the wheel on is good one as I had this trouble before reading about copper slip. Picture me (85 kg of muscle) using a length of timber as a level and pulling harder than an Olympic rower to shift the wheel! Just have to be careful not to get any on your brake disc / rotor unless you want the ABS to cut in unexpectedly.

A very worthwhile video thanks JC. There's an interesting variation on some vehicles, such as the 200 series Land Cruiser, where the wheel nuts have captive washers fitted to them. I assume that the washer is included to reduce steel to alloy friction and perhaps also wear of the wheel. At first I was unsure how to deal with the intermediate friction surface, but have settled on cleaning and lightly oiling the nut-washer interface.

Since most lug nuts are specified to be torqued in a “clean and dry” state, I tend to do so that way. This also lessens the chance that the garage monkey will yield a stud when replacing my lug nuts during mandatory annual state inspection, which is a crock, but that is another topic. If the nuts and studs are lubricated, combined with the overtorque from an impact gun, it isn’t that hard to ruin a stud. To prevent corrosion, I add grease to the stud and outer face of the nut after installation. This prevents corrosion, but lessens the risk that someone will not apply the lubricant torque reduction factor and ruin one of my studs. It is easy to clean off the little bit of grease at the next wheel change before removing and installing the nuts again.

Small tip for stuck wheels on flanges: screw all bolts/nuts on their treads by hand, lower the car from the jack, balance the car a few times and you should see the stubborn wheel wobbling under the car's weight. If this doesn't work just drive a few meters at idle speed with the wheel lose.

My own personal experience of incorrectly tightened wheel nuts could have killed me and my wife. In 1984 (where has my life gone?), I had a Range Rover in Denmark WA. Had it serviced in Albany, and picked it up to drive to Perth. Half way to Mount Barker, the steering suddenly felt wobbly. Pulled up, and found 3 out of 5 nuts on the front left wheel were missing, and the remaining 2 were unwound several threads. Early Rangies handled like a boat, so didn't really notice the deterioration until it was terminal. Pinched a nut off 2 other wheels, tightened everything up and kept on driving. Wheel and studs were ruined, but we lived. Wasn't particularly happy with the service crew at Manley Stanwell in Albany that day.

@peglor 2 ай бұрын

An excellent technique for loosening tight wheel nuts especially if all you have is the factory wrench, but it can be applied to whatever wrench you use, is to position the wrench at around knee height and use your knee (Cushioned by your hand), driven by the calf muscle (Which on most people will quite happily lift more than their weight) to push the wrench upwards to loosen the nuts. This has the benefits of removing your back from the load path, allowing much better control of the force being applied and most importantly it means you and the wrench are a lot less likely to go flying if the wrench comes off the nut or anything breaks.

100% agree with all this. You did something on bolted joints (and wheel studs) a little while ago and this is is consistent with that. I once had to remove a set of wheel bolts (VW) after an ape had tightened them with a giant rattle gun and I needed a 2m extension (scaffold pole) on a breaker bar. The bolts were stretched and dramatically bent like banannas and these gave off sparks at each thread turn. I'm no fan of inept garages like this and wish I'd filmed the shoddy practise. I'll never go back to that place (also their lifting techniques were terrible). Good contnet here!

So I haven't watched the video yet, I'm a mechanic of 17 years experience. I have heard all the things to do and not do, like if you lubricate a wheel bolt it throws the torque reading out. I have a Snap-on torque wrench an auto click style torque bar so no spring. I do wheels up with my rattle gun, the reason is I know what I'm doing and can check my torque at any time with industry leading tools. Would I recommend a DIY guy do what I do, hell no, I do it because of my experience. But let's look at the VW wheel bolts, they say don't lubricate them, well what do you do if you have a Amarok that has been on the beach many times? The rust on the bolts will throw the reading off more than a little grease.

I have found the tools that come with my cars are adequate IF the nuts are correctly torqued. I’ve only ever had problems when I forgot to loosen and properly torque the nuts after a garage monkey has installed them with an impact wrench. Sadly, it is almost impossible to find a state inspection station that will properly torque lug nuts even after I specifically request that. So, I drive home and loosen and retorque the nuts after every mandatory state inspection at the local zoo.

I've always been in the habit of dressing up wheel studs with a welder brush and diesel fuel to clean them up. I've always used a torque wrench and never had problems, so is it safe to assume that the diesel is to be considered "light lubrication" and "dry" torque specs are still correct, as you mention factory studs come with light lubrication?

@richardtite8469 2 ай бұрын

Well said. However torque settings and nut loosen due to vibration, is a bit of a science, and the reduction in torque when lubricated ( which is correct) doesn't always take into account the ability of the nut to remain tightened. Normally in engineering a secondary locking system is used. It would be interesting to do a vibration test on wheel nuts, out of curiousity.

Could you please tell tire shops to do this? The last two times I've either had to change a tire or do a rotation, they had criminally overtorqued the nuts. I'm not a small or weak guy, but the one tire I had to change, I couldn't. I was easily pulling with well over 200 pounds of force (or putting 225 lbs of body weight) to no avail. I was in the middle of the Everglades at 2 AM and ended up having to wait for a road ranger, who also couldn't do it. I ended up using a six-foot long extension he had to get the nuts off. When I last rotated my tires, I had a similar situation. I had to use my arms, back, and legs to apply enough force to loosen them. They only need about 80 lbs-ft for any car I've ever had. That I can loosen with one arm as evidenced by when I torqued the nuts after said rotation and wanted to see the difference.

Hi John, I really enjoy this kind of content , all of the content really. My question is, If there is a specific torque value for a nut should you , as in ,is there, any need or benefit to use something like Loctite? Does the torque value negate the need for its use? Thankyou kindly.

Have always used a tiny tiny smigen of copper slip or something called ceratec which is a lube for brake pads here in the UK and slightly thicker in consistancy than copper grease. have never lost a wheel or had loosened wheel nuts ,even on a Citroen 2CV which only has three on each wheel, the beveled nut heads against alloy wheels tend to corrode and stick to the alloy wheel holes if you dont lube them slightly it also stops the alloy wheel holes from pitting and griping the steel nuts so much that they simply wont let go. Ive never understood why in some peoples cases they have to call the breakdown truck because they cant get their wheels off their car, garages that use air drills to tighten the wheel nuts/ bolts overtighten them and sometimes fail to use a torque wrench properly. If Im doing a lot of mileage Ill check mine once a week, less milage once a month. Tyre fitting centres always say on the documentation to return in one week to have the wheel nuts/bolts re-torqued althougth I suspect many Drivers do not. I check em as soon as I get home and then a week later its worth it if you want to change a wheel at the roadside and get the wheel off easily. It beats the heck out of using a torch you havent got to heat the nuts/bolts up to make them expand enough to loosen them off which can damage your alloy wheels. I once preffered steel wheels on my cars but having bought a low mileage used diesel in 2019 it came with rather silly oversized alloy wheels 19 inch wheels, so im learning to live with them and the incredible cost of tyres for them, although they do seem to be lasting a long time.

Last tyre service I used to my surprise and education used a torque wrench before taking them off and again to put them on. Apparently the Ford I have can be easily overtorqued which will break the studs. They checked the torque before taking them off just incase they had been overtorqued the time before so they could alay the blame to the previous operator that had.

Another distinction: lightly oiled, or light oil applied. (ie. ?? The weight vs the amount before securing) Torque wrenches are quite accurate, the clamping force- highly variable, inevitably based on initial conditions. Lol. Getting a load of workshop hammers direct from Thor, the 2 Piece heads with capscrews and nuts are the real deal (saves a bomb).. - Lets not descend to trading semantics, all too nerdy to turn down.. (A well adjusted torque wrench, so satisfying .) Only final tighten - or loosen with all paws on the ground.

@AutoExpertJC 2 ай бұрын

Both, in the context of the oil on bolts, ex-factory. Agreed that the wrenches themselves are 'accurate' if you actually mean 'repeatable'. Accuracy would depend on calibration. Friction is the big variable affecting stretch/clamping. (Also operator consistency - mainly grip position and speed.)

Would thread lock count as a lubricant when using it? Service guide might say, apply thread lock and tighten to 160Nm. I’m going to do that because it’s specified. However if it’s not specified I use it but experience with this fixing says I should, would the fluid thread lock lubricate the fixings and therefore I should tighten at roughly (*after I do my own maths) 30%.

@AutoExpertJC 2 ай бұрын

Thread locker is a lubricant, but the mounting face is usually dry, so it's not lubricating the whole thing.

@FuManchu5ltr 2 ай бұрын

@@AutoExpertJC … and therefore going back to the point about torque settings relative to new lightly oiled fixings, the thread locker would be assumed similar in nature and not change the specified torque in a meaningful way? I don’t like to assume, however I’m going to assume. I have unlocked some new knowledge today. I really like these technical videos you do from time to time. The rivnut video was good too.

Hmmmmmm In over 30 years of driving, I cannot recall the last time I’ve had to change a tyre on the side of the road or in a carpark due to a flat And that’s because 9.9 times out of 10 A flat tire is due to a slow leak - especially in a CBD setting you’ve run over a nail or a screw or something and it can be a reinflated with a 12 V air compressor and it will stay okay for several days ……. No need to touch the wheel brace……. And As of a few weeks ago I discovered this new product or at least it was new to me called tyre repair rubber screws. You simply take the nail out and screw in a silicon coated grub screw and it seals the leak without having to touch a wheel nut…. Check em out…..!

What about the warning that others give about not using so much anti-seize that you accidentally fill the head of the domed nuts used on the mag wheels etc with so much anti-seize that it cannot be compressed and the nut cannot be fully tighted. Also for those aged and arthritic ( at 71 I am getting close) hitting something with a dead blow hammer or levering on a wrench can be very painful and sometimes somewhat fruitless. As we have discussed before, I think Torque multipliers lug nut tools are a better option worth also considering and no, they are not all made of "Chinesium"; professional quality versions exist and are not hard to find. But even the cheaper sub $100 torque multipliers kits that come in plastic blow molded packs designed be stored in the car boot in my experience are fairly robust - we haven't broken one yet.

This is all very interesting but doesn't touch on one potentially more significant issue . . . . DOOD!! I'm surprised that John didn't discuss the practice of lubing the entire contact face between the wheel and the hub in order to prevent corrosion . . . I have always done it myself until I recently found out that it effectively changes the interface/joint from one of loading the bolts in tension to loading them in shear. Indeed, some high performance cars actually integrate a friction plate between the two surfaces and I have heard of some well lubed-up wheels in high performance cars shearing off and overtaking their surprised drivers. Be warned, by all means lube the little collar in the middle but not the main flat contact face between the wheel and hub . . this should definitely remain dry in order for the joint not to be compromised . . . or so I'm told . . . dood!!!

Something I see an alarming amount is after market wheels fitted without center hub spacers and relying only on the studs to locate the wheel, in the event of loose nuts being driven for a long period often the result is a total failure of the studs and a potential severe crash!
