What is the 1964-1968 Chevrolet Chevelle Four-Wheel Drum Brakes — No Stopping Power for the Horsepower?
Early Chevelles left the factory with four-wheel drums (front discs were not even optional until 1967, and rare after). The single-circuit master cylinder on pre-1967 cars means one leak equals no brakes, and the drums fade badly under repeated or hard stops — a real safety weak… Repairs typically run $400-$1,500. Severity: high.
What is the 1964-1972 Chevrolet Chevelle Lower-Body Rust — Quarters, Wheelhouses, Floor and Trunk Pans?
Like every GM A-body of the era, the Chevelle has no rust protection in the seams. Water sheds off the deck-lid drains and rear window channel into the trunk drop-offs and wheelhouses, and the lower quarters trap moisture behind the outer skin. The result is almost guaranteed rus… Repairs typically run $800-$6,000. Severity: high.
What is the 1965-1972 Chevrolet Chevelle Big-Block Overheating — Marginal Factory Cooling for the 396/454?
The big-block Chevelle's factory cooling package is right on the edge, and a tired or upgraded engine pushes it over. The original brass radiators silt up and lose efficiency, a missing or wrong fan shroud lets the fan pull air around the core, and a worn fan clutch or the wrong… Repairs typically run $300-$1,200. Severity: high.
What is the 1964-1972 Chevrolet Chevelle Frame & Body-Mount Rot — Rear Crossmember and Rails Rust Out (and Bend)?
The Chevelle rides on a separate full perimeter frame, and the rear frame crossmember plus the boxed sections of the rear rails are the weak point. They sit in the spray path of the rear tires, trap mud and road salt in the boxed cavities, and rot from the inside out. Cars that t… Repairs typically run $600-$4,000. Severity: high.
What is the 1964-1972 Chevrolet Chevelle Rear-Axle Wheel Hop — Stamped Control Arms & Soft Bushings Bind?
The Chevelle's four-link coil-spring rear suspension hops violently on hard launches. Under power the pinion climbs the ring gear and twists the axle, and the flimsy stamped-steel control arms with soft rubber bushings flex and bind, so the geometry can't control the axle. It get… Repairs typically run $250-$1,500. Severity: medium.
What is the 1964-1972 Chevrolet Chevelle Tired Charging & Points Ignition — Generator/2-Series Posi & Failing Points?
Early Chevelles used a low-output, externally regulated charging system (early cars even had generators), and the factory breaker-point ignition needs constant dwell/point maintenance, drifts timing as the points wear, and limits spark energy. Original alternators were as little… Repairs typically run $150-$800. Severity: medium.
What is the 1964-1972 Chevrolet Chevelle Cowl & Windshield-Channel Rust — Water Leaks Into the Cabin?
The two-piece cowl/plenum under the windshield collects leaves and debris through the cowl vents, holds moisture, and rots the cowl top, the dash channel, and the lower windshield channel from the inside. The rot spreads up the A-pillars and across the upper windshield channel —… Repairs typically run $500-$3,500. Severity: medium.
