Warning!! Please use handbrake in snow/ice

That is wandering off track.

Glad someone spoke up - I was going to say that myself....

We'll have to crown this thread as "King of Puns" as it's a long reverse up the thread to get to the original point.

I was almost tempted to do that to make sure - picturing a differential in my head was making my brain hurt.

Differentials are easy. Gearboxes are painful!

Hi

You all had me so paranoid that i took the wifes car and raised the rear wheel on the ramp and tried to spoke the wheel that was raised and sure enough i couldn't.

I have made a blunder and gave eroneous information, i am so so ashamed. I could have swore that while wifes car was slipping on the ice in park that one of the back wheels was turning but it couldnt have been. I guess i jumped to conclusion and was relating it to when jacking one side of the car up in park that you get no braking from the other wheel.

I was trying to warn and help others.

I really thought that you needed an LSD to get the braking/driving effect of both wheels simultaneously.


Anyway enough of me trying to justify myself for being stupid.

Don't beat yourself up. Even though your reasoning was wrong, the thought was there. (Did anybody see Top Gear this week when Jezza couldn't park the X6 on a slippy slope without it sliding backwards?)

Yes. What he didn't say -amongst the usual TopGear unscientific testing- was that all 4x4s have a level of slope and a slipperiness of that slope, which will allow them to slip backwards.

In fact they offer no more resistance to sliding backwards than any normal car with the brakes on all four wheels.

What 4x4s offer is more grip for moving forwards than a conventional car as they can transmit the drive through four wheels instead of just two.

Here's a rather nice visual guide to how differentials work: -
