Have you tried a tune-up? Plugs, wires, cap & rotor, cleaning throttle body of coking etc.

Hate to tell you, but it sounds like the center support inside the tranny is bad. Most likely gonna need a new tranny if you want to fix this problem.

Nov 17, 2005 (8:16 pm)
Fuel pressure is good, coils appear to be good, altenator checks good, cleaned throttle body, has new sparkplugs. Never sets a code. I am leaning toward bad injectors or an ECM. Has anybody got any other ideas?
#1686 of 2180 F-150 strange noise problem
Nov 18, 2005 (9:29 am)
I have a 2005 F-150 with 26K miles and there seems to be a strange grinding noise coming from either the drive train or transmission. I'm only able to make it happen when driven for a while, parking it for ~10 minutes and beginning to drive it again. Can't tell where it's coming from exactly as it only happens for ~ 10 seconds and goes away.
Any idea as to to the problem??
#1687 of 2180 Electrical Nightmare
Nov 19, 2005 (3:25 pm)
1994 F 250 7.5 manual trans.
When I have the negative battery cable disconnected I get 12.7 volts between the cable and the negative battery terminal. I have disconnected the starter, alternator, and removed all of the fuses and replaced them one at a time to determine which circuit might be the problem. This is where I get lost as I have five fusses that all trigger the problem. I have even traced it to the next fuse box and have found the following areas to be the problems.
Fuel pump relay
Trailer brake feed
Courtesy dome light, radio clock memory, speedometer, warning buzzer.
ABS, Electrical control, Cruise control.
I can find nothing in common with these elements that would be causing the problem.
Any help would be greatly appreciated.

First, you need to be measuring the amount of current that's being drawn instead of voltage. That would be in amps rather than volts (hopefully milliamps!).
The radio memory will definitely be drawing something, and probably the audio power will as well. Start by putting your meter on its highest amperage setting so you don't overload it if something is drawing heavily, then gradually step down and take note of the readings.

Did you ever find out what the problem was. I'm having the same problem, but only in cold weather.I lose oil pressure off and on when first starting my truck.
#1690 of 2180 Brake Lights Have me stumped
Nov 22, 2005 (6:30 am)
I'm hoping one of you ultra electrical savey people can shed some light on my problem (pun intented). My brake lights have quit working on my "94" F-250. I've checked the fuse and the brake switch both of which are good, and I have current to both. My flashers work as do my turn signals. I'm wondering if the brake light on the back of the cab is in series with the actual brake lights and if that bulb is bad could that be why the lights in the back of the truck won't work, a long shot I know but I'm getting desperate. I have a large fiberglass topper on the truck and didn't want to remove it if this wasn't a possability.
#1691 of 2180 F-150 Super Crew Oil Pressure Problem
Nov 22, 2005 (6:35 am)
When I start my truck the oil pressure gauge fluctuates from no oil pressure to normal oil pressure for a period of time. After a short period the oil pressure will stay ok. seems to happen mainly in cold weather.

It's probably the pressure sensor, but if it's not you could have a more serious problem. You can either replace the sensor, or check the oil pressure independently, preferably with a mechanical gauge. You can probably buy one for less than it would cost to have it checked at a shop.
