Wheel nuts

[ajrl]

I'll be getting a torque wrench for Christmas, where can I find a table of the correct torques? I've been changing summer/winter wheels for over 20 years by feel, thought I would see how far off I have been tightening them...

Also, what size are the lug bolts? I want to try a thingemy rod to help align the wheel as I attach them...

TIA

All I can suggest is to either ask your dealer or email MG's customer service.

Google says the wheel bolt torque is 120nm to 130nm, which sounds right because this is the same for the MG4. As for the bolt size for your thingemy rod, that might also be the same as the MG4 (14x1.5), but I'd pop one off and measure it before buying one.

A Christmas Story. Around 1974 me and my mate Nick set off to go to the pictures in Birmingham in his red Austin A40. Whizzing along listening to the Rolling stones I think, we could hear the sound of sleigh bells jingling. I rolled my window down and said it's coming from the front wheel but we continued into town regardless. Parking up I asked him if he'd done anything earlier to that wheel, oh yes he'd had the wheels off earlier. So we popped the chrome hubcap off and lo and behold he'd forgotten to put one of the wheel nuts back on. I can't remember the film but lets say it was Three wheels on my wagon. Ha ha and a happy Christmas to you all.

My father was so excited to get an A40. He could drive it up the (not particularly steep) hill outside our house in a forward gear, unlike the reverse he had had to use in the previous car (some kind of immediate post war Fiat.)

Happy days eh.

Yes, the wheel bolt torque is also in the owners manual for my ZS EV & I think for all the MG range in the technical specs section.

Just to add, as an ex-tech I will say you should refit wheel bolts 'DRY'. That's how we were trained & manufacturers require this from dealers. Don't worry about your wheel bolts seizing or corroding. They all have an anti corrosive coating usually of zinc chromate or similar. If you do have corrosion it means the wheel bolts have been overtightened. This stretches the bolts & threads causing the anti-corrosion coating to pull apart starting a catalytic corrosive action. One should also be careful when using copper slip on alloy wheels with steel bolts as it can react with the alloy causing corrosion.

It's worth noting that if a professional uses any form of lubricant on wheel bolt threads (or some other fixings) it is not just frowned upon but it can invalidate the techs/garages professional indemnity insurance. This could come into play if ever a wheel came loose. Just saying!

PLEASE NOTE: only use thread lube/thread lock or anti seize on ANY threads if directed to do so by the manufacturer. Additionally, if using thread lock anywhere on a vehicle be very careful to follow the thread lock manufacturers instructions for torque reduction as many still require a reduction in torque on critical fixings. Where a reduction in torque is not specified this will be due to the type of thread lock being used, but check check & check again with the thread lock manufacturers as It's important to get it right!
