Car Forum / Ford / Ford Trucks / August 2006F-150 Overdrive Clunk
Hello - I have a 2004 F-150 4-wheel drive truck. It has recently started to make a clunking noise accompanied with a vibration right around 46 miles per hour, about where it would shift into over drive. Anyone familiar with this problem? How can I begin to narrow this down and do some diagnostics? Thanks! > Hello - I have a 2004 F-150 4-wheel drive truck.

IIRC, the fluid/filter change is specified for 30k mile intervals. Any shift problems or shudder, particularly with OD, are likely related to old fluid. Even if you were under warranty, Ford would tell you that the first thing to do is change the fluid and filter. CJB Make sure you check the U joints. You may have had one go prematurely! This causes a clunking noise and because it is out of round, it causes a rumble when spinning at higher speeds due to imbalance. Been there, had that happen!

JK In all seriousness, even if you find a universal joint problem, you still need to service the transmission if you haven't. CJB Thanks all. I'll start with a fluid/filter change and inspection of the U-joints. >> Make sure you check the U joints.
