The 1972 Plymouth Fury represents Chrysler's full-size C-body platform with a range of reliable powertrains, but age-related issues dominate over design flaws. Biggest concerns are deteriorating front suspension components, carburetor problems on emissions-choked engines, and rust in structural areas.
Torsion Bar Suspension Wear and Lower Control Arm Bushing Failure
Common · high severityTypical onset: 60,000-100,000 mi
Symptoms: Clunking over bumps, Wandering steering, especially under braking, Uneven tire wear on inside edges, Front end sits lower on one side
Fix: Lower control arm bushings deteriorate and cause dangerous handling. Typical job requires removing torsion bars, pressing out old bushings, installing new arms or bushings. 6-8 hours labor for both sides with alignment. Upper ball joints often need replacement simultaneously.
Estimated cost: $800-1,400
Timing Chain Stretch and Gear Wear (All V8s)
Common · medium severityTypical onset: 80,000-120,000 mi
Symptoms: Hard starting when hot, Rough idle that improves with RPM, Backfiring through carburetor, Rattling from front of engine on cold start
Fix: Chrysler chains stretch over time, retarding cam timing 4-8 degrees. Replace chain, gears, and oil pump drive gear simultaneously. 4-5 hours labor for 318/360, 5-6 hours for 440. Critical to check camshaft endplay while in there.
Estimated cost: $450-750
Carter/Holley Carburetor Emission Control Failures
Common · medium severitySymptoms: Severe hesitation on acceleration, Black smoke from exhaust, Stalling in gear at idle, Rough running after warmup, Poor fuel economy below 8 mpg
Fix: 1972 emissions carburetors have complex vacuum circuits, deteriorating diaphragms, and stuck choke pull-offs. Most shops rebuild or replace with remanufactured unit. 2-3 hours labor including adjustment. Many owners convert to earlier non-emissions carb or aftermarket for reliability.
Estimated cost: $350-650
Rear Frame Rail and Torque Box Rust-Through
Occasional · high severitySymptoms: Visible rust perforation behind rear wheels, Rear suspension mounting points show movement, Body sag near rear window, Leaf spring mounts pulling away from frame
Fix: Salt-belt Furys develop critical structural rust where rear frame rails meet body. Proper repair requires welding in new sections, often 12-16 hours labor. Surface rust is manageable, but perforation means expensive metalwork or unsafe vehicle.
Estimated cost: $1,500-3,500
Transmission Kickdown Linkage Wear (TorqueFlite)
Common · low severityTypical onset: 70,000-110,000 mi
Symptoms: Delayed downshift when flooring accelerator, No passing gear, Early upshifts under light throttle, Transmission stays in higher gear climbing hills
Fix: The external kickdown linkage wears at pivot points and stretches the rod. Adjustment helps temporarily, but worn bellcrank bushings need replacement. 1.5-2 hours labor to rebuild linkage properly. Cheap fix that dramatically improves drivability.
Estimated cost: $150-280
Brake Master Cylinder Leakage (Single-Reservoir System)
Occasional · high severityTypical onset: 60,000-90,000 mi
Symptoms: Soft brake pedal that pumps up, Brake fluid level drops rapidly, Wetness at booster/master cylinder junction, Pedal sinks slowly to floor when held at stop
Fix: Single-reservoir master cylinders develop internal leaks, often bypassing fluid between chambers. Complete failure leaves no brakes. Replace master cylinder and bleed system, 2 hours labor. Strongly recommend dual-reservoir upgrade for safety.
Estimated cost: $200-400
Slant-Six Exhaust Manifold Cracking (225ci I6)
Occasional · low severityTypical onset: 80,000-130,000 mi
Symptoms: Loud ticking or popping from right side of engine, Exhaust smell in cabin, Visible crack near heat riser valve, Noise worse when cold, quiets slightly when warm
Fix: Cast iron manifold cracks between ports 3-4 or near mounting flanges. Replacement requires removing heat shield and air cleaner, 2-3 hours labor. Used manifolds often already cracked; new aftermarket quality varies significantly.
Estimated cost: $250-450
Solid chassis and bulletproof drivetrains make these worthwhile if rust-free and suspension is sorted—avoid if structure is compromised or front end is clunking badly.
