2001 Ford Expedition - 4 Wheel Drive Isues? - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

My dad is having problems with his Expedition. The original problem with the 4 wheel drive was that the wheel would wobble, causing noise. After he took the wheel off, the caliper was wobbling approx. 1/4 inch.

He wants to know what would cause this problem so he can fix it, and he also wants to know the torque of the nut in this diagram...

He labeled 'Bearing?' in his diagram, but Im not sure what he meant, I didnt get a chance to talk to him about he just left me a note when I got home.

Any help is appreciated.

The wheel wobble is more than likely from a bad wheel bearing (hub assembly), the location shown in the drawing.

The front axle shaft nut will torque will be 60 ft. lbs but has nothing to do with the tightening of the wheel bearing.

This is what the wheel bearing assembly will look like, they are expensive also, $150-200.

It's a pretty easy change. Remove the center nut, brake caliper, caliper bracket, rotor, unhook the ABS connector, and the 3 bolts holding the assembly. When installing, use blue thread locker on the assembly bolts and a new axle nut.

The item you call caliper in your picture is the rotor. If you put one of the lug nuts on with the wheel off, it should be tight. If not, as jwko said, you'll need a bearing assy.

Sorry, I knew some things on the diagram were wrong, but I just copied what he drew.

But Ill tell him about the lug nut thing, and if it doesnt work, he'll have to make a trip to the Parts Store. Thanks guys. Ill report back eventually with results.

Thanks guys, the suggestion worked perfectly. He changed the assembly, no more wobble!

The only downside is the part was a little more then expected, almost $400 dollars including tax.

On a side note, how long do these repairs usually last? Like, how long until the problem comes back?

We've had some with 300,000 miles and still on the originals.

ExpedIssues · 01-25-2010, 12:04

So I'm assuming it all depends on the wear and tear you put the car through?

These were run pretty hard. Just that sometimes one will happen to go.

The wheel bearing (hub assembly) I've bought have all been 'factory sealed' meaning no grease joint. However, I've had good luck with mine. Most last 60K or more without issue. I abuse my Durango and the left front wore out 20K before the right front one did. It sees a lot of towing during the summer months and the rears are still good! When the fronts went, they didn't wobble much and barely made any noise except at low speeds and doing tight turns (at lock). I'd love to get 300K on a set. Perhaps my next vehicle will.

$400? Was that outright or did that include installation? RockAuto Auto Parts had them at the prices I mentioned above. Next time you are in need of auto parts, give them a look. In the supporting vendor section on this forum, they have a code good for 5% off. If I don't need a part right away, I always buy from them.

I don't know about 4WD, but on my truck I had a bearing go at around 140k and the other is original with 156k on the clock.
