The 1996 Explorer is notorious for transmission failures and front suspension wear, with the 4.0L OHV V6 prone to catastrophic lower-end damage from timing chain/guide failures. These trucks nickel-and-dime you to death after 100k miles.
4R55E/4R70W Automatic Transmission Failure
Common · high severityTypical onset: 90,000-140,000 mi
Symptoms: Harsh 2-3 shift or slipping in 3rd gear, Burnt transmission fluid smell, dark/metallic fluid, No overdrive engagement or limp mode, Shuddering on lockup converter engagement
Fix: Rebuild or replacement required. The forward clutch drum and overdrive servo bore wear are typical culprits. Expect 8-12 hours labor for R&R plus rebuild time. Many shops opt for reman units to avoid comebacks.
Estimated cost: $2,200-3,800
4.0L OHV Timing Chain Guide Failure Leading to Engine Damage
Occasional · high severityTypical onset: 120,000-180,000 mi
Symptoms: Rattling noise on cold start that disappears when warm, Sudden catastrophic noise followed by no-start—chain jumped or broke, Check engine light with cam/crank correlation codes, Metal shavings in oil, low oil pressure
Fix: Plastic timing chain guides disintegrate, allowing chain slap that destroys the block, pistons, and heads. Once jumped, you're looking at complete engine rebuild or replacement—25-35 hours labor. The 5.0L V8 doesn't have this issue.
Estimated cost: $3,500-6,500
Ball Joint and Control Arm Bushing Wear
Common · medium severityTypical onset: 70,000-110,000 mi
Symptoms: Clunking over bumps from front end, Wandering or loose steering feel, Uneven tire wear on inside edges, Visible grease boot tears on ball joints
Fix: Both upper and lower ball joints wear, and the radius arm bushings turn to mush. Plan on replacing all four ball joints and radius arm bushings together—6-8 hours labor. Alignment required after.
Estimated cost: $800-1,400
Rear Hatch Support Struts and Latch Failures
Common · low severityTypical onset: 60,000-100,000 mi
Symptoms: Hatch won't stay open, falls on your head, Latch won't release or catches intermittently, Electric latch motor buzzes but doesn't unlatch, Hatch rattles or doesn't seal properly
Fix: Support struts lose gas pressure and the electric latch motor strips gears or corrodes. Struts are 0.5 hours, latch is 1-2 hours depending on access. Both were recall items but most are aged out.
Estimated cost: $150-450
Intake Manifold Gasket Leaks (4.0L OHV)
Occasional · medium severityTypical onset: 100,000-150,000 mi
Symptoms: Coolant smell from engine bay, no visible external leaks, Slow coolant loss requiring top-offs every few weeks, Rough idle or misfire when cold, White smoke from exhaust on startup
Fix: Lower intake manifold gaskets fail, leaking coolant into the valley or cylinders. Job requires pulling upper and lower intakes, replacing all gaskets and checking for warpage—6-8 hours labor.
Estimated cost: $700-1,200
Fuel Pump Failure
Occasional · high severityTypical onset: 80,000-130,000 mi
Symptoms: No-start with cranking but no fuel pressure, Stalling at idle or under load when hot, Intermittent long crank before starting, Whining noise from fuel tank area
Fix: In-tank pump fails, often intermittently at first. Tank must be dropped for replacement—3-4 hours labor. Use OEM or quality aftermarket; cheap pumps fail within a year.
Estimated cost: $500-850
DPFE Sensor and EGR System Issues
Common · low severityTypical onset: 60,000-120,000 mi
Symptoms: Check engine light with P0401 (insufficient EGR flow), Rough idle or hesitation on acceleration, Failed emissions test, Pinging or spark knock under load
Fix: The Delta Pressure Feedback EGR sensor fails constantly—Ford revised it multiple times. Easy 0.5-hour fix but the sensor costs $80-120. EGR valve and tubes also clog and need cleaning.
Estimated cost: $150-300
Avoid the 4.0L OHV V6 models entirely—the 5.0L V8 is more reliable but thirsty, and all Explorers of this era have expensive transmission and front-end issues that make ownership costly after 100k miles.
