I thought that story might have been about the clear coat getting a little shabby till I saw the pics.

I think the number of recalls Toyota have managed to issue is pretty telling. They are not what they used to be. Cheers

LH threads on wheel nuts or studs have been common on cars and trucks since quite early in the history of motoring.

For the conventional setup, where the wheel is supported by a conical face on the nut, for forward motion, a loose nut will tighten on the right side, but loosen on the left. Visualise the hole in the wheel moving in a very small circle round the stationary nut - the contact point will drag against the nut.

The issue is what is "loose". This depends on the load on each nut - loose means loose enough for movement to occur. This depends on the pitch circle diameter of the studs, the number of studs, the wheel diameter, and the load on the wheel.

In the last fifty years or so left hand threads have become almost unheard of on light vehicles, partly because tyre issues have decreased to the extent that many (most?) drivers rarely touch a wheel nut spanner and cannot be expected to know half have to be turned the "wrong" way, and there is a long history of broken LH studs where they are small enough.

Manufacturers have mostly managed (probably by trial and error) to produce setups where the nuts will not loosen provided they are tightened to where they are "tight" to the average driver. But, as I have found from experience, on a classic Landrover/Rangerover, if you tighten them to where the wheel turns when jacked up, and then forget to tighten after putting weight on it, if it is on the LH side the wheel nuts will come loose!

"then forget to tighten after putting weight on it, if it is on the LH side the wheel nuts will come loose!"
I would have thought that was obvious to most people but of course if you're in a hurry or it was pouring hard or thick like this bloke, it might happen. I'd never heard of LH nuts on cars until a bloke I knew who worked at Telfer 40 years ago was towing a van in with his wife and kids had a puncture and rounded off the nuts trying to undo them. A truck going past took a message in (no mobiles back then) and they sent a fitter out to assist him.
That was back in the days long before the Ripon Hills road was built and it was all dirt and creek crossing from the Hedland/Marble Bar Rd.

Loose wheel nuts can be a problem with ANY make of vehicle and that is why the fitment of wheel nut indicators are manditory on many minesites.
Personally I recheck the wheel nuts a couple of times after changing a flat tyre or even after picking the vehicle from the tyre joint.
It takes about 5min to do this But it Will prevent loosing a wheel from loose or broken wheel studs and it is a Good habit to adopt

They are the biggest seller in Aus by a country mile,over double their nearest competitor,so the more that are sold,the bigger number can have issues.

Over 8.7M vehicles world wide,next is 5.5M,2021.

There is a class action being started for Colorados,panels cracking,DPF issues,etc,etc.Over 90,000 vehicles involved,a huge percentage of the number actually sold.

Ford TDV6 engines in D3/4/5,RRS,should have been a class action as well,but actual numbers are low,although the % of failures of vehicles sold is high,and the manufacturer continued to sell them for decades, knowing there was a problem.
