Ford F-150 (2004-2008) :: Vibration Starts Above 45 MPH - Truck Shake Only When Pulling A Trailer?

I took it to the dealer and they blamed the trailer. I told them that I have pulled two different trailers and it did it with both. Then he said that the trailer was not heavy enough to weigh down the springs. So now I not suppose to tow an empty trailer? Also my father in law has pulled the trailer with his Z71 with no shake and the other belongs to a neighbor with a 98 F150 with no shake. The vibration only starts above 45mph. Any clue as to what could be causing this?

Ford F-150 (2004-2008) :: Misfiring On Cylinder 4 - Changing Spark Plugs

2004 5.4L ... Codes indicate a firing issue on #4 cylinder, figure it's the coil pack. They bought truck used a few years ago and plugs have not been changed since they have owned it. I was going to change plugs while I was under the hood. While checking threads on this engine I picked up on plugs being a major job unless you know the tricks. So what tricks do y'all have up your sleeve to keep from breaking plugs?

Ford F-150 (2004-2008) :: 2007 - Spark Plugs Replacement Every 60k?

My '07 had the check engine come in the other day, engine misfire. I took it to the dealer hoping it was a coil, due to the 100,000 mi warranty from Ford I was hoping would be covered. Sadly, and of course, all coils tested fine, turns out 2 plugs were bad. They replaced all 8 plugs, plus a plug boot. Not one plug broke (truck had 80k on it) so no extra cost there. So much more, but peace of mind that all the plugs are new one piece plugs is great. He recommended that they should be replaced every 60k to avoid any issues.

Ford F-150 (2004-2008) :: 2007 - Changing Rear Differential Oil?

I have a 2007 ford f150 FX2 5.4 with 3.55 limited slip rear end. It has 68,000 miles and would like to change the rear differential oil. I have read and I know the oil it requires is 75w-140 plus the friction modifier. I would like to use mobile one. But was reading and the mobile one sites states that is already has friction modifiers. Is that ok to use on my truck? Using mobile one and not adding the extra modifiers?

Also some other brands say they have friction modifiers as well. Should I use mobile one and add extra friction modifier or just go with what it has already?

Mobil 1 Synthetic Gear Lube 75W-140 LS contains special friction modifiers designed for limited slip-type differentials. In most applications, the addition of special LS (limited slip) additives is not required. For axles requiring the highest level of limited-slip performance, OEM specific LS additives can be added to this fluid.

Prius (2004-09) :: Necessary To Disconnect 12v Battery Before Changing Spark Plugs

I got the plugs for my '06. I hope to put them in in a day or 2. My question is: is it necessary to disconnect the 12v battery to do this? I've changed plugs in other cars without doing so.

Prius (2004-09) Fuel :: 2006 Noticeable MPG Drop After Changing The Spark Plugs

Right now I am seeing roughly 41 MPG and that is after changing the spark plugs with brand new NGK Iridium's, Air intake filter and did an oil change since it was due for one. I have driven the car roughly 2,500 miles since all of this stuff was done and it just seemed to continue to drop to the 41 MPG mark.

What I have noticed though is that when the motor turns off it shudders and the when it restarts while the car is in park the car will roll back and forth slightly. I have also noticed that the car seems to struggle to get up to the posted speed while climbing an incline and also while the car idles in park or at a complete stop there seems to be a bit of a miss fire. Could that be caused by a bad coil? Because I have tried everything short of taking it to the dealer which I really do not want to do again and be told there is nothing wrong with it when I know there is.

Ford Super Duty (1999-2016) :: Trailer Plugs Do Not Work

Went to hook up my trailer today and both the trailer plugs do not work. I checked the fuses and all is well. They worked fine the other day but now they don't work at all. I confirmed this by hooking up to another trailer and nothing. Also got another truck and went to trailers and it worked.

My truck has 19000 miles so it's practically new. I have never seen this. I called dealer but they can't see it til next week and I need the trailer brakes and lights. Where could I look or what could the problem be?

Ford F-150 (2009-2014) :: Tranny Slipping When Pulling Trailer

I have a 2012 Ford 4x4 crew cab 150 xlt. 15,000 miles. When pulling my dump trailer I was stopping to turn and the transmission disengaged. Once I turned the corner coasting the transmission kicked back in again. During this happening pushing the gas did nothing but rev up engine. My dealer said if this happened that a warning light would of came on or a wrench would appear on dash but it didn't. He said then it didn't happen. This happened 3 times in 10 miles of driving. I had it in tow mode.

Ford Excursion :: Odd Sound On Freeway While Pulling A Cargo Trailer

2000 7.3 180,000 miles. It sounded like I was in passing gear from the turbo but not as loud or strong. The tach never moved like it would if it was in passing gear. We kicked it in and out of overdrive, pushed the O/D, no change. Then while driving it would just go quite/back to normal. Oh forgot, this was while pulling a cargo trailer with a total weight of about 4,500 lbs...

Ford 6.0L Power Stroke Diesel :: Disable Glow Plugs While Testing Trailer Wiring?

I drained my batteries enough that I needed a jump after the last time I was troubleshooting trailer wiring, since I keyed on a bunch of times. What fuse or relay do I need to pull out next time? I'm thinking of pulling fuse 302, HFCM relay (or fuse 7 in the disto box under hood) to disable the fuel pump, but what fuse or relay is for the glow plugs?

Ford Transmission :: Screeching Noise When Truck Is Loaded Or Pulling A Small Trailer Uphill

My truck makes a horrific screeching sound when it's loaded or pulling a small trailer (2000lbs) up hill. I discovered last night while I had it in drive, if I hold the brake and give it a little gas (like if you were trying to do a burnout) it will make the screeching noise as well. It won't break the rear wheels loose either, which makes me think it's down on power or the transmission is slipping.

My first thought is the transmission, but some searches on this forum describe U-joints or the carrier bearing as possibilities. The previous owner told me he replaced a U-joint just before I bought it, so I'm not ruling that out at all....

My truck specs: 1995 351 E40D 4x4 (manual transfer case & hubs), extended cab eddie bauer. 158k.

Ford F-150 (2004-2008) :: 2006 - Jerking At 45 - 50 MPH

I have recently bought a new truck this month and everything was nice and dandy till i noticed an annoying jerking at 45-50 mph. The check engine light didn't come on till recently when it got really bad and would barely start. I hooked a code reader up to it and it said cylinder 6&8 misfire. So I had the coils replaced on those two cylinders and it seemed to start and idle better.

So I took it on the interstate to see if the jerking was gone as well. and it still jerks at 45-50 just like before. I was going to take it to the dealership to have them figure out what the issue is but that's 100 bones just to figure out what the problem is. My mechanic doesn't want to mess with the spark plugs because he knows they always break.

Ford Super Duty (1999-2016) :: 2005 - High Oil Temp Whilst Pulling Trailer?

My 05 f-350 6.0 is giving me some problems. I have 311,000 on my truck. It had had its share of problems, at 80,000 it blew its first head gasket. Ford fixed that one!! At 199,000 it blew its second one. I had head studs installed this time. At 299,000 I had to replace two injectors, a new turbo, a egr delete kit, a new oil cooler, power steering gear box, and while I was burning 1000.00 dollar bills I put a new edge cts on it. IOne the way out day one it was 95 temp out side, the truck ran great coolant temp and oil temp stayed around 202 to 204.

Day two 70 degrees my o temp hit 235 while the coolant temp went to 210. Backed off the throttle to 60 mph. Coolant temp dropped to 202, but the oil temp stayed around 217 to 220. I can not make the oil temp go above 198 with out the trailer. The other thing that scares me the most is my coolant level dropped about a half gallon!!! It is not blowing any white smoke, there is no coolant smell or leaks that I can see, and the holding tank has no evidence of being over pressurized. The edge system does not give me any codes except for the two for my egr delete.
