Location: Lockport, Illinois | I tried the diesel-stop and ford-truck forum and couldn't find what I am looking for. My Ford F-350 PSD started to vibrate when I go from 1 to 10 mph in first gear, after 10 mph I am still in first gear and the vibration goes away. I would like to find a trouble shooting guide or a forum that I can find out what is wrong. It is a 4x4. The u-joints are tight, could it be the transmission, flywheel, torque converter, or something else. If anyone could steer me in the right direction I would appreciate it. |

Safe Riding,

Location: Lone Oak, Tx | If you go to the Diesl Stop and scroll down to the 1999-Up Super Duties section and then to the 7.3L Power Stroke Engine and Drivetrain forum, and ask the same question you asked here, somebody will give you an answer, I'm pretty sure of that, or you can do a search about your problem and most likely find an answer. If you can find a member by the name of Richter69, he's a wiz at trannies. Assuming your tranny is an automatic, it sounds like the torque converter. Does it do all the time or when just you are towing and how many miles are on the tranny? Has it ever been rebuilt? Any upgrades to it or is it stock? I can't remember if they put the dual mass flywheels in these trucks or not but if they did that could be a culprit also.
Safe Riding,
Todd

Location: White Lake, MI | It sounds like vibration of the carrier bearing in the middle of your 2 piece driveshaft. The bearing sits in a rubber isolator that can vibrate under heavy loads. The bearing can be shimmed to adjust the angle (I think there are different factory mounts for each wheelbase). The angle changes with compression of the rear springs so it may only vibrate under certain loading conditions. If this is indeed your problem, it's really not detrimental, just a little irritating. |

Location: Henderson, TN 38340 | I bought a Ford once that had a simular problem. The U Joints were tight but one of the caps was not seated right. When the unit would start in a certain position the drive shaft would be off center causing a vibration. Then it would get back on center and everytrhing would be OK. Something to check. Good Luck Turfa |

| I'll betcha today's pay check that it is the bolts that (don't) secure the flex plate to the torque converter.
BTW, I don't get paid today.

Location: Lockport, Illinois | I appreciate all the responses. I have been on the road for the last week and was unable to view this site. I will look in on all the sites and also try to find the problem with all the help I received on this forum. |

Location: Lockport, Illinois | I finally found out what was the cause of the vibration. The center carrier bearing was shot, and one u-joint was cracked. At least I didn't break down on the road and it wasn't the transmission. |
