Recently I had noticed a steady growl while decelerating/coasting. Originally, I assumed it to be a universal, so I replaced what I suspected just to find only one of the four was actually bad. No big. By the growl continued, and in fact progressed to bearing heard and felt under all driving conditions (most noticed not under power). I checked wheel bearing assemblies, ESOF
hub assemblies, front drive axles and dust shields, front differential and fluid... I literally checked all I could...
I broke down, and sent her to the dealer. The Ford diesel master technician believes the issue to be from the trans, more specifically the torque converter and/or pump. I went for a ride with him, and the noise (growl) goes away with the trans is popped into neutral. We listened down by the inspection hole, and its loud as hell. Almost like a rapid crack crack gear noise. I did do a fluid service change, as I do not know the history fo the vehicle. I'm the third owner... And it has 175k on it now. After two fluid changes, the fluid was DARK. Way day. And the magnet, as usual, was fuzzy at first but not bad the second time.
The truck drives fine, no decrease in MPG
or power. No slipping or locking, no pops or cracks or shudders. Everything shifts as it should. I do, however, fear this is the beginning of the end for this trans...
Very long post - sorry about that.... Has anyone encounter a similar situation? Im locked in on the trans and not the cam chain and gears... cuz it goes away in neutral.
