Ford Expedition Noises
Hey guys, i have 2000 expedition, was backing out of driveway, place car in drive and heard a loud clunk in the rear somewhere. Since then, i will occasionally hear a wop-wop-wop-wop, almost like a flat tire sound, or something rubbing. Sometimes it is more metalic sounding. i have been all over the rear end of my truck, removed the wheels and brakes, inspected my coils, shocks, control arms, etc. I don't see any cracks broken bolts, ....nothing. It drives fine, it just makes a lot of noise at very random times, there is no consistency as to when or what conditions it happens with. There may be a slight leak of some sort where the rear axle/housing thing meets the tire. ALso, i believe i have narrowed the sound down to the right rear. Any ideas?
PS. They told me that they've seen the problem on F150s but never on the Expedition, but given the similarities I'm not surprised it could come over to the Exp.
I dont hear the noise anymore... but dang... that was a lot of parts.
I've asked the dealership several times how to pull the vent out so that I could service it myself but they always have to check with the "vent guy" to find out how. They claim that they've "lubricated and adjusted" the vents twice. They haven't chirped since the last lubrication, but I've only driven it once since then so I'm not convinced that it's fixed.
I talked with another Expedition owner who said that he would just pull his vents out and put vaseline on them. However, he has an '05 and the vents simply pop out. Apparently, the '07 vents don't pop out so easily.
I now have a weekend project!
I never got it fixed but figured out the problem..for whatever reason mine stopped doing it.....but the problem is the motor switch or door for the rear AC/Heat gets stuck and keeps trying to complete the transition....i guess mine became unstuck when we switched our rear AC from heat back to AC....since that time it stopped ticking. The noise was coming from the rear passenger side wall panel..kind of between the second and third row seats....mine is under warranty so i will take it in eventually to get it fixed.
Help, I am not under warranty and don't want ot fix something expensive.
I think something just inside the wall can be easily damaged. But I'm not sure.
Now that I am out of (extended) Warranty - I will pull it apart next time to check it out.
Is there anything else under the dashboard other than a heater fan motor which could make such a noise?
The 1st noise is when I put the car in reverse, I hear a single thump after the car has backed up about 3 or 4 feet. It scares me everytime as it feels like I backed into something.
The 2nd noise that I hear is when I am accelerating with the wheel turned. It sounds almost like the tires are rubbing against something, but they are in fact not. I put new tires on the vehicle and the noise is still there.
Does anyone have any ideas as to what these noises could be? Any help is greatly appreciated. Thank you.
No one can tell us. We have had it checked at different dealers.
no answer. :mad:
Question #1 I have found an annoying cricket chirp in the dash when I go over pretty much any sort of bump. (It's winter in Minnesota so the roads have lots of bumps.) The chirp is coming from the dash piece the covers the gauges, speedo, etc. It appears to be coming from the male end of the clip that goes into the dash receptacle. It has a plastic bag like piece that goes over it, which I assume it to reduce any friction or squeaks. I have pulled this part of the dash apart and stuck in felt, cardboard, but no luck. I can make it go away while driving if I place my hand on it. Any one else had this experience and know how to solve it?
Question #2 I had an after market 10.5" dvd player and rear camera installed for the kids. Work great, but another rattle, which I believe is coming from the wire harness that the car stereo shop decided not to anchor down. There is likely 1- 1.5" of room between the head liner and the roof (with the rear A/C vents) it sounds like it is "slapping" when I go over bumps. Any advice to give the stereo shop to fix this when I bring it back?
I've checked everything obvious, including the various exhaust heat shields, but have not been able to find where it might be coming from. Dealer, too has struck out. No relevant TSBs that I can find. I'm starting to think the light-off catalyst media is loose inside the housing. Reasonable guess? Sound familiar to anyone? Other ideas?
I have a loud mechanical popping noise from the front of the car under acceleration. It does it in AWD or 4WD HI. If I remove the fuse for the 4 WD, it won't do it at all. If I am in a turn it won't do it until I straighten up. It will do it with the cruise set at anything up to 70 mph but if you set the cruise to anything over 70 it won't do it. I haven't found any information on whether or not the traction control is disabled above a certain speed. I have changed the speed sensor on the rear differential but have not changed the ones on the front because of the cost.
Has anyone had a similar problem and if so what was the remedy?
has not occured below 55 mph
has not occured above 80mph (don't usually drive above that)
occurs both while towing a small trailer and with nothing in tow
usually begins as a shift point is approached, but continues after the transmission completes the shift
happens much more often while going uphill than when going downhill
if allowed to "build", the noise will develop into an irregular thump that can be felt in the floor by both driver and front passenger
ALWAYS goes away when I take my foot off the gas. Always. Never fails.
NOW the last 2 days , nothing..?????
After the first two or three times I heard this noise I pulled off the highway and looked underneath, thinking I had picked up some road debris that was stuck underneath. Nothing there. I checked for loose heatshields - nothing. The thing I find really odd is that it always goes away as i let off the gas. I can get right back on the throttle and the noise is gone and everything is fine. there's no loss of power and other than the thumping I tried to describe above nothing feels different when it's making this noise. There's no check engine light and everything in the "system test" checks out OK.
I'm at a loss now, scouring the interwebs to see if I can dig anything up. Anyone have any ideas about this?
