Sounds like the signs of bad subframe bushings to me.

When mine went out it had all the obvious signs - loud bang, lots off smoke and a great big hole in the case! I bet that's never been seen before - LOL!
Surprising enough, I drove the car home and had all 5 gears. I wish I had some advanced warning signs.

Would it feel like the engine is moving back and forth when you let off the gas with bad subframe bushings? I just replaced the motor mounts.

To test the SFBs, open the hood, crank the steering wheel from side to side. If the engine moves either sideways or tries to rotate any, the SFBs have slack in them.

Steve, it does exactly that. Ford told me not to worry but I don't like it! How hard are the SFB's to change? Is there any danger in waiting a little while? Thanks for the help.

It probably won't hurt to wait a little while. I have the same problem in a bad way on my car. The dis module has rub marks on it now from hitting something on the strut tower area. My engine moves a lot needless to say. In about two weeks I will be done with my project car though so I will just keep driving it for now. The sfb's aren't really too hard to change as long as you don't have to mess with the recall kit. I would also suggest using the gen3 rear sfb's on all four corners also. Good luck.

First of all, it ain't the guy from Ford who has to drive your car. You do. If it bothers you enough, you'll decide to fix it. If the SFB mounting nuts fail, the subframe can drop with serious consequences. While this isn't exactly an issue with the SFBs themselves, it is something to consider. That's why Ford has the SFB mounting hardware recall for certain states.

HRM... I just did my clutch about 6000 miles ago and it seemed to have gotten worse overtime since then... also I have a noise.. it sounds like something is loose.. I guess when I get home form work today I will be trying to tighten up the subframe... my bushings *looked* okay at the time... myabe time for the aluminum ones now eh?

OH also I remember before I took off the subframe it looked as if there was a half inch gap on the back part of it between the runnber and the floor pan... I would of had to over tq them to get them any farther even still I wasn't strong enough to get them any farther anyway... do you think it is bent or something?

If there is a gap,your subframe is just floating on air.The stock mounting bolts are pretty weak as it is,i`d be nervous of driving the car that way.Also,if the bushings aren`t tight,the frame can`t be aligned,so you`ll also wear your tires.

I know this sounds dumb... but with it mounted that way it doesn't move at all... I wonder if it is bent or something? I mean it was like that ever since the previous owner had the clutch replaced by Ford.....

Well that's part of the problem. Seriously though, don't mess around with the subframe. If it's loose or the bushings are bad take care of it. I can attest to what happens when the subframe drops (Ford installed one of the recall plate nuts upside down on mine) and it's scary as ****, not to mention dangerous.

The exposed part of the subframe bushing at first may look ok, but when removed you'll be able to see the tears in it. If your engine torques when the steering wheel turns they are in serious need of replacement. All this I know for fact from my own personal experiences. Simply put, it's just dangerous.

Gen III subframe busings are solid rubber from what I understand and are of excellent quality. I believe you can obtain those from Ford Parts Network or SHO Shop. JThomas68 I think is also coming out with a subframe bushing prototype for Gen I & II in the near future so you might consider dropping him an email. Other than that, I would suggest the aluminum subframe bushings from SHO Nut. I have mine in hand, not installed yet but I anticipate a new love to develop between myself and my car once they are installed. :)

When you turn the steering wheel side to side, should the motor be totally still with absolutely NO movement? Mine moves side to side a tad.

The torquing that we saw when my 60k was done was a twisting type of movement. Pretty scary too, just ask Huntervf...he said he'd never seen anything like it before. It twisted so much that it put rub marks on my DIS which we originally thought was from a bad motor mount. But it was all the SFB. I believe if you see any movement, it should be very, very, very (get the point?) slight if any at all.
