Since i posted this, the problem has been fixed. I realize that this (based on what I read in the forum) is a fairly common problem. My answer was to replace the rear U-joint. Problem cured!
I've got a 2000 X limited V-10 with 85K and new all terrain tires on it that were balanced and rotated last week.. It drives great, no problems except when I accelerate to speeds of about 48-70 MPH it produces a low end noise (rumble) and increase vibration. If I let off the accelerator, the noise (with the exception of some normal tire vibration) seems to go away.In addition, it seems as if with the cruise on I can find certain speeds that it really is not too bad. For example, at 63MPH it's not bad (still a rumble and vibration) but at 66MPH the low end noise and rumble is much worse. I'm asking now because I've finally made an appointment with Ford service. Is it normal, is resonating frequency, torque converter clutch?, wheel bearing? Any information in hand before it makes it to the dealer would be greatly appreciated!! |

Dan,
Look back to some Forum Threads on Feb 25/26,2004 to get yourself into the loop. Driveshaft balance, u-joint angle, wheel balance, tire cupping, u-joint condition, wheel bearings are some of the possible sources. You need to evaluate them all and eliminate the ones that don't apply to your vehicle and fix the others.
Example: I reduced severe vibration at 67 to 80 MPH by rotating my wheel (front to back) and torquing the wheel lugs to 55 ft lb. Please update your post as you work out your "shakes" so we can all help and gain knowledge.
I love my 2003 white X, Richard Knoxville,Tn
