If you only have one set of snow chains, the general consensus of fitment to a 4WD is on the front – right? I agree with that, makes sense.

So why does the manual for my 100 series rigid axel say to only fit them on the rear?

I can only assume it’s because they either:

1) Rub on the guards.
2) With the increase in traction put to much load on the weaker front diff. I know it’s weak cause I’ve already had 2 replaced under warranty and not really put the car under excessive stress.

So, anyone know what is the real reason for the manuals recommendation, if it’s not one of the above?

I know front is standard in a 2WD for steering traction, not sure about 4WD.

Not that you need them in a 4WD as a rule, i have a brand new pair but a few years old, never been on the 4wd, but it is law in vic to carry them. I would use them on the front as you would have the traction and steering. I know most people with commodores, rear wheel drive put them on the rear...

They shouldn't rub cause they will rip your gaurds apart in no time and you should only do about 40km/h so it should strain the front diff too much. not sure why they say the rear

Hi ChrisB,

Unfortunately I am not sure of the reason, but my manual for a GQ Patrol also says MUST only be fitted to rear (no explanation given).

Not a LC100, but I got a 90 series, and the front wheels when being turned swing back and around, so at one point a shoulder of a stock tyre is 10-15mm or so from the guard. I reckon that chains on a stock 90 series at the front might be in danger of touching esp when articulating, though not sure cause never done it. With my very slightly larger tyres, no way can I put chains on the front now. Tonester.

The first time I was being snatched out of a bog in reverse. The second I was snatching a friend out forwards. I have owned a FJ40 and a 60 series before and treated them badly with no adverse effects. However the 100 series I treat with kid gloves as I don't wish to ruin my 60K purchase. It must be murfy's law that the most expensive vehicle I've ever owned is the one I've had the most problems with.

Snatch recoveries can produce excessive force quite easily.
If the force wasn't excessive the diffs probably wouldn't have broken.
Still, not bad to get them both under w,ty.
