Minor Steering

Steering Damper Failure

Symptoms

Vibration or shimmy through the steering wheel at certain speeds. The steering feels harsh over bumps.

Cause

The steering damper (a hydraulic shock absorber mounted between the steering linkage and the chassis) wears out and stops dampening road feedback. On a vehicle with 33-inch or larger tyres, the steering damper works harder and wears faster.

Fix

Replace the steering damper ($80-200).

This is a 30-minute job with basic tools.

When fitting larger tyres, consider upgrading to a heavy-duty steering damper from a specialist supplier.

Cost mentioned in fix

$80-200

Other known issues

Common Steering

Steering Box Excessive Play

The steering wheel has significant free play before the front wheels respond. At highway speeds, the vehicle wanders and requires constant correction. The steering feels vague and imprecise.

Critical Rust

Floor Pan Corrosion

The floor pans develop surface rust, then pitting, then perforation. In advanced cases, the driver can see the ground through the floor. The seat mounting points lose structural integrity.

Critical Rust

Firewall Rot

The firewall develops rust around penetrations, where the clutch master cylinder, brake master cylinder, wiring harnesses, and heater hoses pass through the bulkhead. In severe cases, the firewall becomes structurally compromised.

Critical Rust

Sill and Rocker Panel Decay

The sills (the structural members running along the bottom of the body below the doors) rust from the inside out. External paint may look fine while the interior is completely hollowed.

Critical Cooling System

Chronic Overheating (F and 2F Engines)

The temperature gauge climbs above normal under load, on hills, towing, or in slow traffic. In severe cases, the engine boils over and dumps coolant.

Common Cooling System

Diesel Engines and Cavitation

The B, 3B, H, and 2H diesels develop pinhole leaks in the cylinder liners and coolant passages. Coolant loss with no visible external leak. White residue around coolant hose connections.
