Wheel nuts too tight

I thought 110 ft.lbs was the specification for Landcruiser wheel nuts.

For mags its less but I no longer have it so working from memory

What was the question again LOL

Here it says 150ft lb Mags are 110 I think.

For the 14mm studs on the 5 stud models, it's 150 ft-lb for steel wheels and 97 ft-lb for the factory mags.

For the 12mm studs on 6 stud Landcruisers, its about 100 ft-lb for steel and I think about 85 fl-lb for the mags.

I think 150 is too much - I give it about 110 and check them occasionally when travelling.

Was alluding to the 5 stud 100ser as thats what I had.

I would think the manufacturer would have a pretty good idea of the correct settings . After all they make the things.

Must be set at that for a reason

Did you apply some nickel anti seize on when replacing nuts?

I do it after every flat tyre I have and it works a treat. No tight nuts ever.

No one likes a rusty nut!!

Cheers

Yep I have been for a few years now.

Use it on my spark plugs too.

Sorry my reply was for the topic poster, but I'm glad you use anti seize.

Do people who travel remote remember to take this on their long trips??

My tub of it never leaves my ute.

Thanks

Its a great tip for everyone. Works a treat.

Hi
Anti-seize /anti-scuffing paste can reduce friction at the threads by 30% - so you can over tighten without realising.
Large engine manufactures (on marine engines) advise oiling threads on critical fasteners such as head & bearing studs.

Wheel studs or nuts should never be lubricated, torque figures are for dry assembly only.

Well I'll be damned!!

Had a slow leak on back right tyre ( I could the air cause I had pulled up)
and my first thought was this topic!

I quickly organized my tools and get into it.. Now these wheels had being replaced previously before pick up ( mine LV) but with a bit of brute force they came off a treat!
On with the anti seize and I was on my way. Simple, done in no time!!

20 - 30km down the road a quick re tighten and all good!

Do people on their travels do this???

Cheers

I have always used a little smear of grease on all my wheel studs prior to tightening a wheel.

Been doing this for 60 years and never a problem yet.

This applies to Van, Box Trailer, Boat Trailers and cars, never had a loose nut yet or one I couldn't remove.

Steel , alloy, all the same.

When i get tyres changed the vehicle is in sight all the time to make sure a rattle gun isnt used. Seen too many studs broken or striped by tyre places & then had to repair them for customers. Modern cars dont have mutch metal in the disks any more & over tightening can distort the discs & cause shaking of the steering wheel & brake pedal pulsing on aplication of brakes.

I would assume that the main reason you have not encountered the problem of wheel nuts being too hard to undo is that you or a another trustworthy person has been in charge of the previous tightening.
The grease will help the threads but won't be enough to stop the taper on the nut binding with the wheel if it is over tightened.
I think overtightening has caused the problem Racinrob has bought up this time.
I use anti cease on the wheel studs on my taxi as well. The wheels come of at intervals of a max of every 3 weeks. If some mug lays into it with the rattle gun that is set to high they are pretty hard to budge as well.
I have an air rattle gun in the shed & only use it to remove wheel nuts.
I always tighten them up with a wheel brace.
The mechanics I use, who actually are trained tradesmen, unlike tyre fitters, use a rattle gun. But they have the skills & knowledge to do a far better job than I or some of the untrained tyre fitters that are out there.
Some times I have seen a torque controlling extension used on the rattle gun. Not sure how accurate it is. It is a short thin extension bar that flexes to a predetermined torque.
Hopefully somebody can give some info on how effective these torque things are.

When i was working in a Ford dealership the problem with over tightened wheel nuts was so bad on AU Ford & on models, the dealer was suplied with Torque control extensions from Ford.

I once watched a tyre fitter put the torque control extension on and use it to tighten my wheel nuts. I challenged him about using the rattle gun on my wheels. He said he could not overtighten the nuts with the extension on.

He was wrong!

I got home and put a 1.5 m bar on to get them undone.

On one occasion I asked my local tyre shop not to use a rattle gun to tighten the wheel nuts - hand tighten please.

Lucky I always check with a cross-brace - all 24 were finger tight!!! I guess they took me at my word.

Always, always, always check them if wheel or tyre work has been done, or even regular service - they take the wheels off to check the brakes (well, they should).

Trailer too.

G'day Ian.
Watch out for those tight nuts mate. That can get serious.

I don't know about studs snapping while driving & have only myself seen that happen while trying to undo them.
But in the days when I drove falcon taxis I have seen the studs & nuts changed because the threads were shot from being over tightened.
These days I use better quality mechanics & tyre fitters & I haven't seen that for some time.

snapping studs with tight nuts - no extra comments required, although could get a run in friday funnies

cheers - bb

I walked into the Doctors yesterday wrapped in Glad Wrap.

The Dr. said, I can seely clear your nuts. LOL LOL

You had better invest in new wheel nuts, ask any engineer.

So it is the nuts that have their thread stretched not the studs? I thought so.
When I mean spin on/off, I meant they are easy to undo now. Do you think I should replace them?
Thanks

Definitely Easy to undo easy to pop off due to less thread.

Would there be any stretching of the thread on the studs? They are ok to keep?

I have seen broken studs from overtightening and I have seen broken studs from undertightening. (Did that one myself...whoops)

After having work done on the car, particularly at a tyre shop, I go home and loosen the nuts then re-fit using a torque wrench.

Since I commenced this practice I have never hada problem. But I still carry spare studs and nuts in the toolbox.

Easiest way to check is buy some new nuts and if theyb bind you need new studs as well.
