rear hub nuts

[TJC46]

Hi guys could someone please confirm which side of the car the left hand thread rear nut is on. Stupid me removed the hubs and driveshaft and did not mark which was which. Im now rebuilding all the chassis/ suspension etc and want to put them on the correct way round. I apologise in advance for being dumb.

Right hand (drivers) side is left hand thread!

Wot he said. ^^

Pretty sure it is on mine, I will check tomorrow.

[big geoff]

its the same as a truck wheel nut fit it to the near side it stops it undoing.

Haven't had the rear suspension apart recently have you?

[Barkychoc]

Yes both front and rear.
I've replaced the NSF wheel bearing and it was definately RH thread (blue nyloc insert on the nut).
I'm not so clear in my head about the rears.
The Sierra Haynes manual I have (4 cylinder) surprise surprise completely contradicts itself.
I'll check it out tomorrow as I think its kind of handy to keep the wheels on the car.

Yeah, well, I s'pose you might have a point there.

OK the Haynes Sierra manual states the on the front the nearside is RH Thread and Offside is LH Thread.
Haynes state rears are the other way round - the nearside is LH thread and Offside is RH thread.

I think this makes sense - as the front nuts are inboard inside the hubs - and on the rears they are outboard on the end of the driveshafts so relatively speaking the nut / shaft rotation is opposite on the same side of the car.

I need to check my rears - but the fronts certainly comply with the sierra data - and its not as if you can fit the front hubs to the wrong side of the car.

They should be arranged so that tightening the nut turns it in the same direction as when the car is moving forwards.

I think i know what im doing now, only im dyslexic and have f##kin turets. So wish me luck, thanks to one and all.

It's the rear nearside wheel that comes off wedges. So it needs a left hand thread to stop it unwinding when not torqued up.

I know this is a dead topic but all the above depends on whether you have a car which is LHD or RHD.
The way to remember is that the hub nuts tighten in the direction the wheel turns when the car is moving forward. This is so they do not come undone as per comment above.

I had a mate who argued that clockwise could go both ways.

'What if you are looking from behind the clock' he said

What a ridiculous comment


For clarification

Front wheel Drivers side Left hand thread…(Yellow Nyloc)It doesnt matter if its a LHD car or not... the wheel turns in the same direction .
Passenger side Normal thread (Blue Nyloc)

Rear wheel Passenger side Left Hand thread…(White Nyloc) …
Drivers side Normal thread (Green Nyloc)

Just noticed something here......................

Whilst the road wheels still turn in the same direction and the nuts still do up in the same direction on a LHD car .......... the steering wheel is on the other side (and they drive on the other side of the road too!) So referring to near side, offside, driver’s side or passenger side will confuse things somewhat.

I think the easiest way to refer to the direction is: All hub nuts tighten in the same direction the wheel turns (when going forward).

Not guilty m'lud and I beg to differ. This is not just semantics. When people on forums discuss "drivers side" as the key identifier then my comment stands.

Your listing above is quite correct but I would counsel against using nyloc colour as an identification. I have a set of brand new hub nuts here sourced from a well known TVR spares supplier. Each of them has White Nyloc inserts: however the left hand threaded nuts are marked with a scribed line across each of the six flats.

I was trying to point out that left handed threads are specified to avoid a component coming loose in service, and on the rear hubs they are fitted to the side where the wheels rotate anticlockwise.

Because the front hubs are mounted with the nuts inboard they follow the convention you have laid out above, but in all cases each of the 4 nuts tightens in the direction the roadwheel rotates relative to the nut itself.

As I am sure you know, some buses and trucks have wheel nuts which follow the same rule.

Mmm If you tap a hole from the back of the plate instead of from the front... will it give you a LH thread?... (a question asked by an apprentice one day)...


Just thought I'd add this in for you?

Only if you tap it while upside-down, facing north and balancing an open tin of custard on your left foot. (PICs required of anyone trying this).
