Bumping and knocking noise in drive train

My 98 2.0 Escort has 237,000 miles on it. Original auto trans and engine, I am experiencing a knocking noise coming from the drive train or trans. I can feel it through the gas pedal and the floorboard.

Does the noise happen while running at idle in park or only when moving?

Re: Bumping and knocking noise in drive train

It usually does this when traveling at speeds 30 and above, it seems to be getting worse. I checked the CV boots they look new,dry and no cracks. I tried to move the half shafts as one would check a worn out Driveshaft, they are tight with no movement. Could it still be the half shafts or in the Trans. Every 30,000 miles I change the trans filter and fluid. Maybe it is time for some repairs.

Re: Bumping and knocking noise in drive train

I have a 99 Escort, and I had a knocking problem that kept getting worse too. Though I have not fixed it yet, I did take it in to my mechanic to find out what was wrong with the car (trying to sell it), and he said it was a crack in the flywheel and I would need to replace the flywheel and torque converter.
Although my car is actually worse while idling, and usually improves once I get past 20-30 MPH, so might not be the same thing, but could be worth checking out maybe. According to the mechanic who found this, it's not a common problem, though caused by wear and tear - he's been in business for 15 years and said he's only ever worked on three cars with this problem, so...
