Fords 4 wd system

[johe]

Hi,
Many new makers use Haldex AWD/4WD systems, Honda has it's own as Subaru does. What about the Escape 4wd? How does this awd system work? Is it cluch/pressure diven as Haldex or like the old TorsenDifferential from Audi, not present any more. Early Escape 2001-2002? Had a swich on/off 4wd . Do anyone have my interrest?

They have a PTU that always sends power to the rear. There is a coupling device in the rear. The early gen 1 had the switch between AUTO and ON. In auto, on demand (slip or high throttle input) it would split torque mostly to the front unless slip or high throttle input, then be up to 50/50. In On it was locked at 50/50 (so whatever coupler is in the rear is locked and no slip).

OK, si I just got an '08 Mariner 4WD: is that an old-fashioned hard connection driveshaft to the rear wheels?

Seller said he 'recently' (3-4 K miles) had maintenance done on the transfer case, but I haven't fully absorbed all the dox in glove compartment.

Do you have any knowledge/experience with just pulling out that shaft, and reverting to basic FWD?

TIA

On my 08 I had disabled the 4wd by pulling the 4wd fuse. It was good for about 2 MPG in the city on my 08 Hybrid. You will have the yellow wrench light on at all times though. If you do mostly speeds over 45 you won't notice any difference as at those speeds the 4wd disables itself anyway.

So they made a AWD Hybrid?

Hmmm...
