Afternoon all,
Recently my 2001 V10 has been making squeaking/rubbing sounds. It comes on when coasting and slowing down below 30mph. It does not go away when brakes are applied so doesn’t appear to be brakes. I’ve tried to isolate it but hanging out of the vehicle with door open as I coast down the street isn’t the smartest thing. When coasting the squeak frequency is fast and slows in frequency as vehicle slows down. Almost as if something is rotating. Will not make any squeaks if in park and I rev the engine. If you have some areas to start looking at, I would appreciate the advice.
Thanks
Josh

sounds like a bearing or a dragging brake caliper. simple preventative maintenance to check/grease. Even if doesn't fix the issue, about 1 hr to accomplish and will help greatly extend the life of these components.
Calipers: They are a nuisance about dragging due to the stupid slide pins. Easy fix. Several guides here on FTE and Youtube. never hurts to check/lubricate. DO NOT OVER-LUBRICATE!!!!
4x4 hub: while checking the brakes, take the rotor off. remove the abs sensor. Using a good Lithium based grease, inject into the ABS hole. rotate the hub. repeat until the hub won't free spin anymore. Should take constant hand pressure. put the ABS sensor back in and re-assemble. Even if it's not the hub, this will extend the life of your hubs. they ship with virtually no grease.
4x2 bearings: there are videos on Youtube on how to check and grease. super easy to do.
It is 4x4 and yes it has ESOF. I will look into the items y’all mentioned.
For reference this Excursion sat for 3 plus years in my neighbors driveway before I finally convinced them to sell it to me. I replaced all the brake rotors and pads when I got it because it squealed like a school bus.
The reason I asked about whether it was four wheel drive with ESOF was I had an issue a little while back with one of my automatic hubs not disengaging and it made a similar noise. Replaced both hubs and the noise went away. Jack the front end up and rotate each tire while watching the u joint inside the steering knuckle to make sure the axles are disengaging.
I agree with Tylus, sounds like brag caliper drag. I had a similar thing happen to my rears and I ignored it until they seized and smoked! I replaced them with SSBC kit and there has been no troubles since.
I had a caliper stuck and got it freed up. I removed the caliper and pads, using an old brake pad and caliper collapsing tool I fully depressed 1 piston at a time, I then released the tool, leaving the old pad in place and depressed the pedal to extend it. I did that about 6 or 7 times to both pistons, calipers work fine now.
Universal joints... look for signs of 'rust' around the rubber bearing seal. Often when driving slow enough you can hear what you can't at higher speeds.
So I started the process of lifting the truck to pull tires and check slide pins. Saw this. My boot is gone and the clamps are still there, just loose. Could this make noise?
slip joint needs to be greased. Once I pull the 4 bolts for front of drive shaft should I just whack the drive shaft hard to get it to come loose?
That usually makes a “clunk”. Never heard it squeak. Make sure to MATCH MARK all 3 pieces of it before removing. It needs to go back exactly as it came apart.
I used generic bearing grease on those splines. Nothing special. Just needs lube. The blueing wears off and allows a little slop. Which then “thunks” or clunks on takeoff.
edit: and yes, give her a good whack if it doesn’t come loose easily. They can rust into place
for the slide pins, a small tube of brake grease is what I always use. Nothing special. Just high temp brake grease like you’d use to lubricate the pad eyes

Good advice on marking the orientation of the slip joint. If it doesn’t go back just like it came apart, your driveline will be out of time, as in “timing”. This is not a joke. I just happened to catch a class eight driveline out of time about a year ago. The other mechanic who put it up this way had never heard of this issue.
