Hello all,

I recently bought a 2000 SD XLT, V10, Auto, 4x4 with 34k on the odometer from a local Ford dealer with a good reputation. I bit the bullet and went with an extended warranty the dealer offered.

I have had it back once for a loose heat shield underneath that they fixed. What I am noticing (and don't know if it's always been there) is a vibration and a droning sound at around 2000 rpm under acceleration. The vibration isn't a strong one, but goes away above and below 2000 rpm. It does this in or out of 4wd. The droning is loud enough to notice, but isn't terrible.

I know this is a truck and expect some truck-like behaviors like a little noise, vibration and bumpiness. I just don't know how much of this to expect.

I did look for another v10 auto on the lot and around town to test drive - no luck.

Any thoughts?

Thanks

 

Does the vibration occur in neutral & park too? If so, it may just be a slight engine imbalance. If not, you'll need to check out the rotating parts. I'd start with re-balancing the tires. If that doesn't fix it, then check the rear driveshaft balance.

 

I've seen a few SD's now with this concern and it appears to be pretty much normal. That's just the RPM that the engine seems to set up a natural vibration. Ford TSB 01-1-3 tells about a new Y-pipe for the exhaust to get rid of a "miss" feel. I replaced one on a F350 with a V10 and it did seem to smooth it out a bit but you could still feel something there.

 

Welcome to FTE ! Lots of good folks here! Here is my standard cut and paste flutter response. If you need more info. let me know.

On my truck flutter occurs right at 1800 rpms. If you have metallic chattering sound then "welcome" to the flutter club. It is very common with the V-10's. Several things may cause it, ways to fix it easiest (cheapest) to most difficult (expensive). 1.) Since you have a 4x4, like me, you have heat shields on your "Y" pipe, they have been known to come loose and vibrate. You can re-weld them, or put hose clamps around them to keep them tight. The best option, take them off and place them in the trash can. 2.) The metal close out plate that fits between the engine and tranission is not secured at the bottom. If you crawl under your truck you can actually take a small screwdriver and pull this plate back. You can take a pair of pliers and gently bend the plate away from the transmission housing about one quarter of an inch. I went further and put a bead of silicon between the plate and transmsission. 3.) A set of Banks or Borla headers No more noise and a increase in power. Because the V-10 is not a naturally balanced engine vibration at 1800 rpm seems to be a common problem. Also, take a look at that cheap piece of junk Ford calls a "Y" pipe, you will then understand.

More questions ??? Let me know...

HI!
my truck do'es the same before and after 2000rpm
70mph @2000rpm 50mph@2000rpm in low this has
been going on since new. 2050rpm it stops
if you put in neturel at 2000rpm it stops, it's not in drive train.
The only thing mine is a diesel . It's at the dealer now!

good luck dozdoz

 

Does it have factory tires? If so, are they Firestone A/T's? If so, I bet they are the tires....that vibration sounds alot like the one I have. Rotate the tires and change the air pressure to see if the tone changes. This might be the problem. Just a thought.

 

Thanks for all the repsonses. It vibrates (and drones) right at 2000 rpm... nothing before and nothing after. It does it in low gear accelerating or high gear on the expressway (65mph). It does not do it in neutral. It is noticeable enough that on a lunch run, a co-worker commented on the "noise" and "humming" my new truck made...

The tires are new (part of the deal) and seem to be quiet. I insisted on a 4 wheel alignment also as part of the deal.

I had it in the dealer a week ago for the heat shield rattle and they said they fixed it with some clamps. A Ford part number even showed up on the receipt for the clamps. Yesterday, the heat shield vibration came back...

I am scheduled to take it to the dealer tomorrow to have anti-squeak pads installed for the leaf springs. We'll see what they say!

Thanks again!

 

Your truck wouldn't happen to be white with some holes in the bed from a fifth-wheel hitch? Sounds like you are having the same problems (rattle & vibration/drone) that I had with my '00 F250 XLT SC, SB 4x4. Several trips/days in the shop without any kind of resolution. Ford eventually gave me some "assistance" in getting out of that truck and into a new one.

 

Between the engine Bellhouse and front of the auto transmission is a 1/16 or 3/32 flat sheetmetal plate that can, under certain rpm conditions make a bunch of vibration noise that you can feel with your hands, butt, and feet...... many trucks here in centeral texas have their "flutter" problem fixed by bending this plate so it will not flex and vibrate......

Worn, out of ballance, Firestone tires will give you fits also. I know of two SD trucks with many new parts installed before the owner replaced the tires and inadvertantly "fixed" the problem. Actually only proves that some service reps are not too smart.

This post is NOT ment to imply that "flutter" is a myth..... just that on these big complicated trucks there are many things that can cause annoying noises and vibrations.......like warped brake rotors and out of balance rear drive shaft halfs....

Good luck tracking it down

 

OMG! FRED!!!!

How the hell ya doin'? Haven't heard from you in a very long time! Hope you're doing OK.

 

NoMo........Got too busy to keep following and posting... plus all my forum "friends" went trolling for a better site....

Actualy my post under yours was a troll of my own.... hunting you!

Oh damn... forgot ... vibration cures and cauzes

mbear2k: Your gut instinct about it being a big truck and expecting new, different, or constant noises is pretty much what you will have to live with. They are not Cadillacs.

However in your case I would track it down. Things that are speed or RPM dependent are never good, and should be fixed.

Even if it is the worn misballanced tires... a flat on a SuparDuty at 70+ MPH will cause a laundry problem every time!

 

There is no better site than this one! Luckily, they still let me hang out here... even though I got rid of my SD and have a GMC 2500HD now. Was getting worried that maybe Uncle S. sent you off to your demise. Hope you and your better-half are doing OK. And I hope to see you hangin' around here more often.

 

Proffessional Grade? Oh NoMo say it ain't so
