I have lost drive to the rear wheels?? - 2002 Land Rover Freelander

lost the user guide, it covers all that in glove box
is is free here in USA google the users guide and bingo.
RWD opts if even allowed is there. in said book
FORD.
the manual (ours) shows 3 dial settings,
only 2wd is one.(no sure me how this works)
or is the car have this.
TRAC-AUTOMATIC 4 selctions not just 3.
FOUR-WHEEL DRIVE SYSTEM??????????????????
2H in this box is RWD only, rear wheels.

2H in the manual
2Hposition delivers power only
to the rear axle.

Possible electric clutch? If it is a clutch and has separate forward and reverse clutches, the forward clutch, control wire or clutch actuation magnet could be loose or bad. Good luck.

It is nearly impossible to drive a true four wheel drive on normal roads because the front wheels travel further than the rear wheels there is soon wind-up between the axles and one wheel must be jacked from the ground to release it so a little further can be driven.

It is for that reason such measures as an overrun clutch is used in the drive to the front or a viscous coupling to the rear, effectively making road cars into part-time 4 wheel drive vehicles. In the case of the former the front wheels will only drive noticeably when traction is lost to the rear. This makes it difficult to check whether there is drive to the front.

Raising the rear of the vehicle on level ground, using a wheeled trolley jack and then gently attempting to drive forward will soon prove whether there is drive to the front wheels.

If there really is no drive the fault is likely to lie within the transfer box or any electronic control system and more research will be needed.

Elaine,

not work, do tell what makes you think it dont work (a lamp) or tires slipping or dead tires. (by tires mean that and traction)??????????

what mode fails, of the many, and where.???????



first off, we dont know what your tires are touching.

on road, or off road. pavement or ICE or snow.

that matters big time . (you read manual and match MODE to Road)

your lost operators guide explains all that, right?

eg: how and when to use, 4wd, its all there. I promise.

ControlTrac 4-wheel-drive system



here are the mode. which one , gives you problems.



quote ford with comments.



What are the modes, and how do they differ?

(note this is the operational behavior of a 2008 Ford Expedition. Newer and older Expeditions will vary only slightly)



• 2H 2-wheel-drive with high range gearing (1.00:1) Rear-wheel-drive capability,

2-wheel electronic traction control system is enabled



• 4A 4-wheel-drive Auto with high range gearing (1.00:1) Full-time all-wheel-drive capability, ((best on pavement or any time)

Electronically adjusted torque split to front & rear wheels, Electronically variable center differential,

Front driveshaft & rear primary driveshaft allowed rotational speed difference,

4-wheel electronic traction control system is enabled



• 4H 4-wheel-drive with high range gearing (1.00:1) Part-time 4-wheel-drive capability, (not for dry pavement EVER)

Continuous 50/50 torque split to front & rear wheels, Electronically locked center differential,

Front driveshaft & rear primary driveshaft mechanically locked with no rotational speed difference,

4-wheel electronic traction control system is enabled



• 4L 4-wheel-drive with low range gearing (2.64:1) Part-time 4-wheel-drive capability, (off road usage, mostly)

Continuous 50/50 torque split to front & rear wheels, Electronically locked center differential,

Front driveshaft & rear primary driveshaft mechanically locked with no rotational speed difference,

4-wheel electronic traction control system is enabled, ESC and RSC are disabled



In 4A mode the center differential is electronically-controlled and rear drive wheel bias. The on-board computer monitors for any sign of rear drive wheel slip (loss of traction)

If loss of traction is detected, the center differential is told to send a share of the engine\'s torque to the front drive wheels. It will not let the front driveshaft turn at the same speed as the rear driveshaft.



What about traction management?

1997-2002 model Ford Expeditions offered an optional limited-slip rear differential (LSD). A conventional open rear differential was standard along with the conventional open front differential and the electronic locking center differential.

comment with out LSD, one tire can spin, on say ice.

but the other 3 tires dont, in full time.

There is probably no need to contact the BAR though you always have the right reserved. Trouble Code P1774 indicates your Mini's rear wheel speed sensor lost its signal, and trouble code P1775 indicates the right rear wheel speed sensor lost its signal as well. Both more than likely triggered during the dynamometer portion of the smog check inspection; while the front wheels are turning and the rear wheels are stationary. During this time, as far as the ABS system knows, the rear wheel sensors have lost their signals.
After a computer reset and driving your Mini Cooper for a few miles everything should return to normal, as apparently they have; and you've passed the smog check. Should the check engine light return in the near future for the same trouble codes P1774 and P1775 we'd recommend inspecting the rear wheel speed sensors for possible debris build-up. Since these trouble codes where triggered during the smog check and smog check machine failure we can assume the trouble codes were temporary and not related to any physical problem with your Mini Cooper.

youre transfer case is stuck in 4wd ther are two control modules on the treansfer case one or both are not working correctly

Here is an idea just move it and see what happens? I think low is to the rear, but that was a long time ago when i worked for GM dealers

FRONT WHEEL DRIVE IS THAT THE FRONT WHEELS ARE WHAT DRIVES THE CAR AND THE TRANSMISSION IS IN THE FRONT REAR WHEEL DRIVE MEANS THAT THE REAR WHEEL DRIVE THE CAR ALLWHEEL MEANS THE THE FRONT AND REAR WHEELS DRIVES THE CAR FOUR WHEEL DRIVE MEANS THAT YOU CAN HAVE ONLY TWO WHEELS DRIVE THE CAR OR AL FOUR WHATEVER YOU PUT IT IN

I have the same car. Mine is automatic. What is yours?

Possible scenarios:

1/ Is the FWD on the dash panel lit up? This will tell you that only the front wheels are engaged without power to the rear wheels. The manual tells you if you have a flat tire in your car, you have to make it into a FWD by inserting a fuse in your fuse box. Check and see if the circuitry isn't shorting out your awd which is making it fwd.

2/ Because the car has open diffs in the front and rear axles, you (or your friend) might see only the front wheels spinning and not the rear wheels. The power is transfered to the wheel with lowest resistance. With the front wheel spinning, one of the rear wheel(s) should also spin. Might not be a solution but maybe you can't see the rear spinning wheel because it's spinning on the other side.
