At about 2K rpm in all gears, on acceleration I hear what sounds like a saw thru sheet metal. My 93 Lightning did that and it was the cats rattling inside. That would break my heart to have to get an off-road H pipe. Anyone been thru this one?
Thanks
Don

Might be the same noise I get. I don't think it is the cats. It was there with the stock cats and is still there with aftermarket cats. The noise shows up on moderate to heavy acceleration from 1500 - 2000. It is a scary noise, makes you instinctively lift off the gas. But once you lift for a sec it goes away. Sound familiar?

noises

It appears under accel at about 2k, has a screechy metallic sound but goes away or gets quieter as the car warms up. I need to have the windows down and be next to a rail or wall to really hear it. It justs sounds off and then quits as the rpm climbs higher. Car is running fine with no noticeable issues. (Other than the clunking 2-pc d/s.)
Thnx

Clutch???

I don't think so but I can't say no either. It doesn't slip or do anything that would make me think that. I've owned several manual trans cars and I would tend to think that if it made noise or acted stupid on release. I was hoping this might be a typical or frequent problem like water leaks or dead batteries. I think it's something in the exhaust. When the monsoon season ends I'll crawl under it and beat around. Thanks guys. If I find anything unusual I will be sure to post.

I have the same sound its around 2300rpm for me and also need to have the window down or be next to a wall to here it. I brought it to the dealer this past week and they said they didn't here anything and everything is tight under the car. I'm going to go back and take them for a test drive. The sound only happens under load. It won't do it if I rev in neutral. There is a TSB out for this issue. Its with the spacer plate connecting the transmission to the engine. TSB 08-02-10 is what the fix is or you can try fixing it yourself.

Read the following about this issue.

If you are still having this noise, you may want to have it diagnosed at the dealer to make sure everything is functioning as intended. They would be in the best position to determine the cause. Please PM me your VIN, contact info, mileage, and dealer if you would like additional assistance.

stupid metal rattling noise at 3k rpm! EDIT: SOLUTION FOUND 9/7/07 - MustangForums.com

BINGO!!!!

My bet would also be the plate between the engine and transmission.

I loosened the bottom bolts on the plate and put some foam pad (like you use between a truck cap and the bed, or foam insulation like you would stick on a door frame) between the plate and the bellhousing on the contact points. Tightened the bolts back down.....rattle gone.

How hard was that to do? I have been to lazy to do it and just been dealing with the problem.

Noise

Scupking - that sounds like it could be the problem - sounds like thin metal plate-hear it ~3K rpm only under accel. I just had heart surgery so my wife would kill me if she saw me or found out I was jacking up the car. I'll get one of the boys to do it. Thanks
I didn't think I would be the one and only with that issue.
Thanks again.

It's very easy...the hardest part was jacking up the car.

noise gone

Bradleyem-that is the fix. I used electrical rubber tape and the noise is gone. 2 plastic ramps and a 9/16 socket and ratchet and done. Wife doesn't know. I just had open heart surgery in March so it hurts to exert upper body but somethings you just can't let go.
That would have been a dealer trip if I didn't post here. You can't beat on anything under there and hear any noise. The bolts were NOT loose.
Thanks you guys.
The junker sound is kaput.

DokterD,

I guess you are lucky your wife did not catch you. For the future, I do recommend a dealer visit to be on the safe side. I am glad you were able to resolve the noise. Now go rest up!

I need to do this. How many bolts are there and did you use just the normal black electrical tape? I will go buy some ramps this weekend so I can get this done.

noise gone

I had a roll of some rubber electrical tape, tho' it is not adhesive. It's like a ribbon of soft rubber. I think it's an insulator of some type, but you can use door/window seal or something like that. I used what I had. 9/16 socket or combo for the 2 bolts. Very easy fix, not worth it to make a trip to a dealer and all day loss or more of my car. Total time for the job was less than 30 minutes from get ramps to put ramps away. You could do it in less time.

I have this same EXACT sound on my car.

I tried the piece of foam between the plate and transmission but it didn't seem to work. Perhaps I need to use more of it.

I am 100% positive it's the same thing you guys are hearing, so it should have fixed it.

I dunno

It worked for me. I folded the tape to get a x4 thickness. This stuff is like rubber. The sound is similar to cutting thru sheet metal with a circular saw. This fix worked for me so far. I wish they had a fix for the clunky drivetrain. Maybe I should wrap the D/S in this stuff.
You don't know how junky it sounds until u change your stock LCA/UCA arms to poly bushing arms. Can't imagine the noise with bearings.
Will an aluminum D/S help to get rid of some of that racket?
Seal614--check out the link in Scupking's first post. Maybe there's some help for u there.
I preferred to attempt the fix myself before losing my car to the dealer for a day +. No harm no foul. If it didn't work I could remove it and then suffer the dealer.

An aluminum D/S will get rid of about 50+% of the clunking. I just had a shaftmaster 3.5" one installed about 2 weeks ago. I have no vibration and tested that up to 120mph. Also she accelerates better. I say its a good mod to have.
