Sounds like its stuck.this was never a good system. if you have the owners manual follow it to a T. ussually if you find a dirt lot engage the 4x4 run it for a few then shut it off. then back up ten to twenty feet this will set things right

1999 Ford Expedition . Door says use 255/70/16. Can I use 255/70/16 on Front and use 265/75/16 on Rear.Thanks


You can use the site for Discount Tires and look up tire specs, like how far the tire travels each revolution. This site will also have substitutes. What you need to be careful of is the anti-skid and anti-lock brakes. Also if you engage 4 wheel drive with different size tires on each end of your vehicle. The sensors make corrections when each tire rotates at a different speed than another.

4 wheel drive lights flashing while I'm driving 97 ford ranger


There's a good chance the electric shift motor is bad. Can you tell if you're in 2-WD or 4-WD? Making a slow, sharp turn will feel different - difficult, clunky - in 4WD.

It's possible to get a manual conversion kit, but that won't solve the light issue, which wouldn't matter at that point, anyway. It could also simply be a wiring problem, with current not getting from Point A to Point B. Checking the OBD II will probably give you several codes, which might help.

I had the electric switching on my Expedition, and it went bad. Not cheap to repair.

Why does my 4 wheel drive not work all the time?


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.

My 02 Ford expedition started to shake when I turn it on what should I do


If your vehicle is a 4 wheel drive, than you are probably driving in 4low or 4 high on dry pavement. Put it back in a4wd (automatic 4 wheel drive) position and this shaking when turning should stop.

FRONT WHEEL BEARING NOISY


Most likely it is a Hub bearing worn out. If you have access to a highway with a sweeping curve the outside tire turns faster than the inside tire following the curve. So if the noise increases on a left curve, the right side is bad. If the noise increases on a right curve, the left bearing is bad.

You did not state whether you have 4 wheel drive or 2 wheel drive.
The 4 wheel drives have the Hub bearing. Check around for parts prices. The price can vary by $100 from store to store. If you have the 2 Wheel version it is much cheaper to replace and you will need a wheel bearing seal.

Do spend a little time checking the other components in a 4x4 as the additional components can also make noise.

NEED TIRES


You can easily tell if you have 4wd by looking under the suv to see if there is a transfer case o nthe rear of the transmission as well as a driveshaft going to a front axle.

My 2000 Expedition seems to bind when making left and right turns. The back wheels appear to be dragging.


you need to check the front axle U-joints out by the wheels,they start to bind up when you make sharp turns,the U-joint won't flex and will need replaced

When i turn sharp while reversing (out of the drive way) the front end makes a very loud noise, sort of like a rubbing or something grabbing. Also when in 4 HI or 4 Low i can bearly ever turn without the...


if you are turing sharp, your tires may be rubbing. a way to check is turn your tires all the way to one side and look under on both sides and then turn them the other way and do the same thing. while you are looking under the vehicle look for any shiny polished metal. this will be a sign that your tire are rubbing.

As far as your problems with 4hi and 4low, if it happens on dry pavement, that is actually normal. your four wheel drive system is set up to engage to assist with traction. your tire while doing so will be rotating at different speeds as needed to ensure proper traction is achieved.
