I recently purchased a used 2000 4x4 limited PSD. It has 36K miles and when braking, there is a vibration. Sometimes pretty severe, other times hardly noticible. Is this a common occorunce? I am going to put new pads and have the rotors turned. Do the rotors come off easily, or do I have to dissasemble the hubs as on older 4x4s? Thanks for all of your help. I just completed a 2000 mile trip and I got 16 mpg running 75-80 and on one stretch running 65 for aobut 200 miles I got 18mpg.

Search the TSB on the site (FTE) you'll find some answers to your braking question. Mine does it. These trucks seem to be hard on rear rotors. Have had mine done twice (41K miles on it). next time I'll be replacing them. 
Hubs do not have to be removed to remove the disc.

The brake pulsating issue is a common problem, particularly on my X. If you ever rotate your tires, make sure you (or the shop you're having rotate them) torques the lug nuts to spec. Overtorquing the lug nuts on these vehicles will cause the warped rotor syndrome.
I have had my rotors machined 3 times now and will be going on #4 when I hit 45k miles.

erlong!! howdy! I just recently registered my X over @ superford.org and actually left you a message on the boards over there. Did you get it? Good to have you over here! No offense but I found those boards a bit bare... :-(

I had my rotors resurfaced twice and replaced twice under warranty. I now have 49K miles and I am off warranty. Does anyone know what the approximate cost of new rotors will be if I need to replace them again?
Thanks.:-)

Hi Monsta,
Yes, I got your message on the other forums. I agree that they are bare. Seems like the Excursion folks are scattered around a few different message forums and really don't have a home yet, which is why the forums are a little bare. What can ya do, though?

What would cause the pulsating to be intermittent? It seems that I have a slight shimmy before I hit the brakes and that is when they really vibrate. Other times they seem to work fine?

Light apply seems to make the vibration more pronounced. I believe it is because they are floating calipers. When you initially or lightly apply the brakes, the pulsating doesn't move the caliper but as you increase brake pressure the pulsating is "absorbed" by the floating caliper design. Once the warpness reaches "critical mass" the no matter what you do you'll feel it.
We all know rotors warp either because the wheel was torqued incorrectly or there is too much heat build-up. I believe the pads could be the culprit. I'm not sure of the compound of them. If any one can shed some light on this subject, by-all-means, let us hear it.

You probably only notice the pulsating right away when you apply the breaks because you start to slow down afterwards. Since the rotor is "out of round" on its surface, the pulsating effect will feel worse when first applying breaks and especially at higher speeds. I am always reminded that my rotors are warping when I come off of the highway--the dashboard vibrates like crazy.
Around town, you don't feel the pulsating, but if you pay close enough attention, you'll feel the pads "grabbing" the rotor during each revolution and it will feel somewhat like you are pumping the brakes.
I attribute the warped rotors to incorrectly torqued lug nuts because almost every time I have had the wheels off to get the tires rotated, the shop doesn't retorque correctly and I "all of sudden' begin to develop warped rotors again. It's like clockwork. These rotors are definitely more sensitive than any other truck I've owned.

[updated:LAST EDITED ON 16-Jan-02 AT 08:43 PM (EST)]Wanna hear something strange? When I got my driveshaft replaced the pulsating stopped. ...Fer some reason, that just don't sound right... 
I thought my rear rotors were crappin' out again. It felt JUST like it did before. So much so, that I didn't even give a thought that it could be linked to my driveshaft. But I guess it was. Somehow...

Monsta-
Why did you have the driveshaft replaced, and was it with another factiry shaft of CV? My vibration also occurs sometimes tihout applying the brakes. However, when I feel this vibration and then hit the brakes it will shake your teeth out. any ideas? I am going in to have the rotors turned tomorrow.

Since you're gonna turn the rotors tomorrow, "report" back and tell us if that was the problem. I also had my left, upper and lower ball joints replaced and that could have been the source of my braking vibration.
As for the driveshaft, you'll be able to tell if your's is worn by listening for a clunk when you take off. You'll roll maybe a foot and then you'll hear it. My new driveshaft is different than my old in that it has, what appears to be, a counterweight/balancer on the axle end rather than smooth all the way down like my old one. I've seen other '00 X's with ones like my new one, so I don't know what's goin' on.
Kinda wish I would have done each repair seperately...then I'd know what created the vibration.
Good luck!

Monsta-
Ball joints confuse me, what exactly are the ball oints on the 4x4? Also, wasn't there a TSB about this? I cannot seem to find it anymore, although I did have some documentation on it when I originally bought the truck. I don't think turning the rotors will solve all my problems, as the vibration is there when you haven't applied the brakes sometimes.
