how to lock the wheels on my jeep?
 

Cherokee Jeep, 1997, Auto, 4Litre, ..

I've managed to get the vehicle stranded a few times, with the wheels
revolving in thin air..., and even with two wheels on the ground, had to be
pulled out (soft sand, wet, uneven ground)
Question is.. is it possible to lock the wheels on each axle? seems to me
that would be sensible.

I am a woman, of course, so I need all the help I can get!


Tks

Re: how to lock the wheels on my jeep?
 

Yes, with practice it is possible to get all 4 wheels spinning. I find
it is more likely to just get 3 of them going, but have managed all 4 a
few times.

It is an old trick and involves using the brakes to load up the torque
on the wheel that is spinning free. The owners manual in both my Jeeps
mentions it but doesn't go into a lot of detail. The book says to use
the emergency brake to load up the free spinning wheel.

With a normal open differential like you have, the engine sends 'equal'
torque to both wheels on each axle setup. So lets just talk rear for
ease with one wheel on ice and one on dirt. The one on ice spins and
you go nowhere fast as you found out.

Both rear wheels see the same torque. The one spinning on ice needs
'very' little torque to free spin, so the other side on dirt sees the
same 'very' little torque.

The owners manual says to put on the emergency brake in this situation,
but I find a hard hit with the brake pedal works best while giving it
gas. This hit with the brake pedal wants to stop the free spinning
wheel so it loads up the torque on it by trying to stop it from moving.
The torque will climb way up and eventually become enough that the wheel
on dirt that sees this equal torque will break free and start spinning
on the dirt. Bingo, away you go shooting 2 rooster tails.... I have
managed to get all 4 shooting tails on slush/ice bottom.

Something like the free wheel sees or only needs 'say' 1 ft lb of torque
to spin on ice. The brakes load it up to 'say' 100 ft lb and the wheel
on dirt only needs 75 ft lb to start spinning free.

It does take practice and it does work. I have never had any luck using
the book method with the emergency brake, but hitting the brake pedal
hard while giving it gas works well for me.

I had a similar question a while back and was pointed to this link. It
explains open, limited slip, & locked differentials very well.

Re: how to lock the wheels on my jeep?
 

In addition to what others are saying, keeping all four wheels on the ground
is a good idea too. You can lock the wheels together with special equipment
or even with the brake method, but this is more stress than the system is
designed to handle. People who regularly get wheels in the air invest in
heavier axles, special differentials and equipment that we ordinary mortals
can only dream of.
