    I have a similiar problem. My F-250 6.0 has 50k miles on it. While pulling a travel trailer, if I quickly let off the accelerator I will hear about 4 loud knocking sound. I took it to a Ford dealer and they assured me that that was a "normal" sound that the 6.0 diesel made. It did not make it for 50k miles so what has changed? Also, before the loud sounds appeared the diesel would lose power and barely pull its self up a hiway hill. Then it would clear up after about 6 miles and run fine.

This is normal, it may not have made this sound before and now it will after an ECM re-flash. I'm not sure what they changed durring ECM updates to Fords but I do work for international which makes the engine. I have heard of this complaint several times and I've also heard of alot of complaints about a lack of power associated with it. The best way I can explain all of this without knowing what ford changed is that they must have lowered the amout of boost pressure allowed durring certian events. This is done by venting the boost pressure which makes the sound your hearing. I know plenty of people that have complained to Ford about this and none of them seem to get a good explination from Ford. DONT always blame the dealer though. If Ford is anything like International they don't always release a full report on what they are changing in an ECM and why, we just get letters saying we need to re-flash an ECM when we pull up the VIN number when a vehicle pulls onto the lot.

Under my 2004 dodge grand caravan hood near the tire we hear a ticking noise which goes faster as we drive. Slows down when we slow down. What could it be?


Could be engine related or driveline related. Do you only hear the noise when the car is driving down the road? Or does it also
happen when the engine is running and the vehicle is in park?

I have a 2002 chevy surburban and it makes a whining noise.


the noise happens running down the road or parked? Is the car a four wheel drive? The alteanator can go bad and whine, the wheel bearings can go bad and whine, windows not fitting right can make a whine The altenator will stop whining if it's unplugged, if this fixes it the battery and the altenater need tested and a bad battery can make the altenator whine and it still be OK. Don't run the engine with the battery disconnected as this can blow alot of expensive stuff and the altenator.

Lack of power misses at road speed smokes on occation dealer said injectors were missing randomly no engine light no power when cold hardly pull it's self when cold 04 powerstroke 6.0


sounds like a good fuel system clean is needed! also make sure there is a clean air filter, as they kill alot of power and will end up causing more fuel to **** through and partially burn giving smoke!

There is a whinning noise when I shift from park to dive for about 2-3 seconds then no noise at all shift fine driving down the road.


Try changing the oil and filter in the trans...use an additive such as lucas along with the oil. If the noise is from something minor that may help. Otherwise, you will need someone to run it on a lift and see just where the noise is coming from.
