The 1961 Plymouth Fury represents the last of the unibody Plymouths before the '62 redesign, sharing the B-body platform with Dodge. These are generally solid cars mechanically, but age-related deterioration of rubber components, ignition systems, and specific weaknesses in the pushbutton transmission controls create the most headaches.
Pushbutton TorqueFlite Cable Linkage Failure
Common · high severitySymptoms: Pushbuttons feel loose or don't engage properly, Transmission won't shift into selected gear, Cable housing separated or corroded at firewall junction, Sudden loss of all gear selection
Fix: The cable-actuated pushbutton mechanism deteriorates with age, not mileage. Cable housings crack and corrode where they pass through the firewall. Original cables are NLA, requiring custom fabrication or sourcing from specialty vendors. Expect 4-6 hours labor to remove dash bezel, fabricate/install cable, and adjust linkage properly. Many shops won't touch it, sending you to a transmission specialist.
Estimated cost: $600-1,200
Timing Chain Stretch and Wear (V8 engines)
Common · medium severityTypical onset: 80,000-120,000 mi
Symptoms: Hard starting when engine is hot, Rough idle with timing set correctly, Rattling noise from timing cover on cold start, Loss of power and poor fuel economy
Fix: The 318, 361, and 383 V8s use single-row timing chains that stretch over time. Original nylon cam gear teeth can also shed into the oil pan. Requires timing cover removal, new chain and gears, new cover gasket, and harmonic balancer reinstallation. Budget 5-7 hours labor. While you're in there, replace the fuel pump eccentric and timing pointer. This is preventive maintenance on any untouched high-mileage example.
Estimated cost: $450-800
Torsion Bar Anchor Corrosion and Failure
Occasional · high severitySymptoms: Front end sits noticeably lower on one side, Clunking noise from front suspension over bumps, Visible rust perforation at torsion bar crossmember, Front wheel camber suddenly out of spec
Fix: The torsion bar rear anchors rust through the crossmember, especially in rust-belt cars. This isn't just surface rust—the hex socket for the adjuster bolt corrodes away entirely. Requires welding in repair sections or replacing the entire K-member/crossmember assembly. Quality repair takes 8-12 hours including alignment. Half-measures with bolt-on brackets don't hold. Inspect this carefully before purchase on any northern car.
Estimated cost: $1,200-2,500
Single-Reservoir Master Cylinder Leaks
Common · high severitySymptoms: Brake pedal gradually sinks to floor when held at stops, Visible fluid weeping at master cylinder casting, Low brake fluid level despite no external leaks at wheels, Brake pedal goes soft after car sits overnight
Fix: These single-reservoir masters leak internally past the primary cup, especially after sitting. The system has no redundancy—total brake failure is possible. Rebuilding originals is false economy; install a new or professionally rebuilt unit. Takes 2-3 hours including bleeding the entire system. Many owners convert to dual-reservoir masters from later models for safety, adding another hour and minor bracket fabrication.
Estimated cost: $250-500
Generator Voltage Regulator Failure
Occasional · medium severitySymptoms: Ammeter shows continuous discharge or pegged charge, Battery repeatedly goes dead or boils over, Headlights surge in brightness with engine RPM, Dome light stays dim even with fresh battery
Fix: The mechanical voltage regulators on these DC generators fail from normal wear of contact points and thermal cycling. Testing requires a known-good regulator to swap or proper ammeter hookup under load. New regulators are available but quality varies wildly—NOS or correct reproductions recommended. Installation is 1 hour, but diagnosing charging system issues on 60-year-old wiring can add 2-3 hours troubleshooting time.
Estimated cost: $150-400
Rear Leaf Spring Slipper/Slider Wear
Occasional · low severityTypical onset: 60,000-100,000 mi
Symptoms: Squeaking from rear suspension over bumps, Rear axle appears shifted to one side when viewed from behind, Uneven rear tire wear with thrust angle misalignment, Visible separation at spring slipper pads
Fix: The rear springs use a slipper/slider arrangement where the front eye rides in a bracket. The bronze or composite pads wear, allowing lateral axle movement. Requires spring removal, new slippers, and potentially new front spring eyes if worn oval. Most shops charge 4-5 hours labor per side. Alignment afterward is mandatory. Many replacement slippers are incorrect thickness, requiring shims.
Estimated cost: $400-700
Buy one if the body and frame are solid—mechanical parts are available and straightforward, but rust repair and deteriorated pushbutton linkages will drain your wallet fast.
