1998 Ford F-150 Problems

What owners report

Owners of the 1998 Ford F-150 most often describe a corroded fuel tank strap breaking and letting the tank drop toward the road, sometimes dragging or spilling fuel; this is the dominant theme in the sampled complaints and appears across a wide mileage range, including well under 100,000 miles. A second cluster involves 5.4L and 4.2L engines: spark plugs blowing out of the cylinder head, and coolant leaking into the intake that hydrolocks the engine. Front-end and body items — rusted tie rods, broken torsion bars, water entering the cab — also come up, along with speed control and shift-cable concerns covered by older recalls.

   Fuel system

   Fuel tank strap corrosion and tank detachment

   • 189 complaints (14%)
   • median 140,000 mi at 13.5 yrs old (174 state mileage)
   • 8 mention a crash, fire or injury
   • owner-quoted repair $700 (median of 8 quotes)
   • filed 2003–2021

   Complaints describe a fuel tank strap or bracket rusting through and the tank dropping while driving, sometimes at highway speed. Owners report hearing a loud scraping or banging noise, then finding the tank hanging or dragging, and in several cases the tank was punctured and spilled fuel. Repairs ranged from replacing straps and bands at an independent shop to a dealer replacing the tank; some owners say they were told nothing could be done or that the vehicle was outside the recall. Reported from about 36,000 miles up to roughly 230,000, with many under 100,000; several owners mention salt-belt states and corrosion as a factor.

   What to check: Look under the rear of the truck and inspect the two fuel tank straps and brackets for rust, flaking metal or thinning, especially on vehicles from the Northeast or Midwest. Ask whether recall 11S21 was performed, and check for a fuel smell or recent tank/strap replacement paperwork.

   “Gas tank straps broke from 1998, F-150. The gas tank fell to the street while driving down the road. I did not immediately realize this, but saw sparks in rear view mirror and pulled over. I had been dragging a leaking gas tank for several hundred yards. I could have blown up.”

   “Was driving and fuel tank fall off and hit the ground, putting holes into the gas tank. My daughter researched recall's and found out there was one on the fuel straps that caused them to break. Ford will not approfve paying for and fixing my gas tank, which I feel should be done because it was their fault that the fuel straps were bad and I never got a recall. Am 79 years old on social security and they want $700 to fix gas tank. …”

   Engine cooling

   Coolant entering the engine and hydrolock

   • 48 complaints (3%)
   • median 100,000 mi at 8.0 yrs old (38 state mileage)
   • 1 mention a crash, fire or injury
   • owner-quoted repair $3,450 (median of 10 quotes)
   • filed 2000–2019

   Complaints describe white steam or coolant loss, then hard starting or no-start, followed by a knock and white smoke from the exhaust. Mechanics told owners an intake manifold gasket or cracked manifold let coolant into a cylinder and bent or broke a connecting rod, requiring an engine rebuild or replacement. The 4.2L V6 and the 5.4L are both named in these accounts. Reported from about 64,000 to 127,000 miles, often noticed after the truck sat for a period or on first start.

   What to check: Check the coolant reservoir level and look for sweet-smelling white exhaust or steam on start-up; ask whether the intake manifold gasket or manifold has been replaced.

   “About two weeks ago, I noticed that my 1998 Ford F-150 had steamy white exhaust upon start and it would last until sufficient warm-up. At that point, I did not think about it much. At any rate, I went out of town for two weeks and upon my return from my trip, I got in my truck and tried to start it and the engine would not turn over. Initially, I thought it was the battery so, I tried to jump start it to no avail. Next, I tried push starting it and initially the wheels locked up but eventually it started. …”

   NHTSA complaint #10141826, filed 2005-11, 97,000 miles

   “My 1998 Ford F-150 only had 79,000 miles on it and was well-maintained. On 8/10-07, the coolant level light came on when I arrived home. I checked the coolant level immediately and there was no coolant in the reservoir. I filled the reservoir and planned to take the truck in to the mechanic when he was open during the week. I only drove the car about 20 miles that weekend and I monitored the coolant level and temperature. Everything was fine. That monday morning, loud knocking came from the engine and white smoke came out of the tail pipe. …”

   Engine cooling

   Spark plug blown out of cylinder head

   Mentioned in 4 of 60 sampled complaints

   Owners describe a loud bang followed by a misfire and rough running, with the truck left stranded or running poorly; a mechanic finds a spark plug has left its hole in the cylinder head, sometimes while towing. Repairs described include thread repair inserts or a head job, and complaints mention quotes well into the thousands of dollars. The issues are concentrated on the 5.4L V6/V8 and 4.6L engines. Mostly reported between about 64,000 and 150,000 miles, under normal driving and towing.

   What to check: Ask whether any spark plug has blown out or been repaired, and whether thread inserts were used. A shop can check torque on the plugs and look for evidence of prior thread repair in the head.

   Tie rod separation and front-end steering play

   • 89 complaints (6%)
   • median 83,963 mi at 6.9 yrs old (32 state mileage)
   • 11 mention a crash, fire or injury
   • filed 1998–2017

   Owners report steering suddenly feeling loose or losing control, with a loud noise, and a mechanic finding a tie rod had separated or broken; some say the original tie rod ends had no grease fittings. Wheel alignment complaints describe front tires toeing in after a tie rod let go, and others mention restoring control at low speed only. Repairs replaced tie rods and ball joints. Reported between about 60,000 and 140,000 miles, typically during turns or at low speed.

   What to check: Have a shop inspect the inner and outer tie rods, ball joints and idler arm for play or rust before purchase, and ask whether they have been replaced with greasable parts.

   “While attempting to back up my vehicle(1998 Ford F-150 4 x 4 6 cyl) I thought I was hung up on something as there was a great deal of resistance in doing so. When I got out to check for obstructions in the roadway, I was horrified to see that both of my front tires were facing each other (toed in). After much ado, and many men stopping to see what my problem was, I learned that the front passenger side tie rod had let go without any warning! …”

   NHTSA complaint #10045882, filed 2003-11, 62,000 miles

   “While making a sharp right turn driver's side inner tie rod detached. When this occurred consumer had no control of the front driver side wheel. This almost resulted in an accident, but the pick up was going at a slow speed and the driver was able to maintain control of the pick up. The tie rod could not be lubricated. The inner tie rod was replaced.”

   Fuel system

   Rusted through fuel line leak

   • 110 complaints (8%)
   • median 148,000 mi at 13.6 yrs old (100 state mileage)
   • 6 mention a crash, fire or injury
   • owner-quoted repair $750 (median of 5 quotes)
   • filed 2001–2021

   A smaller set of owners describe a strong gasoline smell and fuel running along the driver-side frame, traced to a cracked or corroded fuel line and replaced at a shop. Others describe fuel leaks starting near the tank area after strap corrosion. The complaints focus on the odor and the visible leak rather than on a specific repair procedure. Reported from roughly 48,000 miles upward; corrosion is the recurring theme.

   Recall 11V3850001 related service bulletin

   What to check: Smell for fuel around the driver-side frame rail and check the metal lines from the tank forward for rust or damp spots; ask when the fuel filter and lines were last serviced.

   “On monday august 11, 2003 I noticed a strong odor of gasoline on my 1998 Ford F-150 pickup. I found that gasoline was running along the driver side frame and leaking rather heavily onto the payment. I immediately drove to a nearby automotive service center for examination. I was subsequently advised that the fuel line had a crack and was the cause for the leaking fuel. According to the service technican the crack appeared to be unknown including any damage. I had extended warranty insurance with geico for the $277.87 replacement line. …”

   NHTSA complaint #10032842, filed 2003-08, 48,186 miles

   “The brackets that hold the fuel tank straps have rusted along with the straps to the point that the tank may fall off. I believe that this is the same problem that caused the failure of the straps rusting through. This can create a fire even after the straps have been replaced because the whole structure of the fuel tank support system is failing.”

   NHTSA complaint #10441142, filed 2011-12, 140,000 miles

Buying note. Inspect the fuel tank support hardware for rust before anything else, and confirm whether the 11S21 fuel tank strap recall was completed. Have a shop check the spark plugs, cooling system and front steering linkage, since those are the other areas owners write about most on this model year.
