What is the 1960-1967 Volkswagen Bus Inadequate Front Drum Brakes and Single-Circuit Master Cylinder?
Through 1970 the Bus used drum brakes at all four corners, and the earliest Buses (through ~1967) ran a single-circuit master cylinder. A heavy, slab-sided Bus on four drums fades badly on long descents and stops poorly in an emergency, and the single-circuit master cylinder is t… Repairs typically run $600-$2,500. Severity: high.
What is the 1960-1979 Volkswagen Bus Structural Rust in Outriggers, Jacking Points, and Cab Floor?
The Bus carries its loads through the floor-to-rocker structure rather than a separate ladder frame, so the front outriggers, the integral jacking points, the lower bulkhead/cab floor, and the battery trays under the rear seat are the structural backbone. Mud, road salt, and cond… Repairs typically run $1,500-$12,000. Severity: high.
What is the 1960-1974 Volkswagen Bus Perished Rubber Fuel Lines and Engine-Bay Fire Risk?
The carbureted Bus routes rubber fuel hose through a hot engine bay, and old or non-ethanol-rated hose is attacked by modern ethanol-blend pump gas. The rubber hardens and cracks at the very places that matter, at the flares and under hose clamps, weeping fuel onto a hot engine. Repairs typically run $60-$400. Severity: high.
What is the 1960-1979 Volkswagen Bus #3 Cylinder Overheating and Dropped Valve Seats?
The air-cooled flat-four runs hot in a heavy Bus, and the rearmost cylinders (classically #3) sit downstream of the oil cooler in the cooling-air path, so they receive pre-heated air and run hotter than the others. Combined with a lean carb, retarded/over-advanced timing, or miss… Repairs typically run $900-$6,000. Severity: high.
What is the 1960-1979 Volkswagen Bus Worn Steering Box Causing Wander and Vague Steering?
After decades of service the worm-and-roller (worm-and-peg) steering box wears in the center of its travel, so the box develops slop right where you spend most of your time on the highway. Combined with the Bus's tall, flat-fronted body and light front end, this produces nervous… Repairs typically run $200-$1,000. Severity: medium.
What is the 1960-1966 Volkswagen Bus Weak 6-Volt Electrical / Charging System?
Early Buses left the factory with a 6-volt generator system that was marginal when new and is genuinely inadequate today. The low voltage means dim headlamps, slow wipers, lazy hot-start cranking, and constant battle with corroded grounds and undersized wiring where even a little… Repairs typically run $250-$1,200. Severity: medium.
What is the 1975-1979 Volkswagen Bus Type 4 D-Jetronic Fuel Injection Gremlins (1975-1979)?
US-market late bay Buses got the 2.0 Type 4 engine with Bosch L-Jetronic / D-Jetronic electronic fuel injection. Fifty years on, the analog FI is reliable in principle but plagued by aged wiring: brittle insulation, corroded multi-pin connectors, and especially poor ground points… Repairs typically run $150-$1,500. Severity: medium.
