If you own or are considering buying a 1968 Jaguar 3.4/340, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to suspension: Look for uneven tyre wear, listen for clunking over bumps, and check if the car pulls to one side. A bouncy ride suggests worn shock absorbers. Visually inspect coil springs for cracks. At 51,218 average miles, these vehicles are in the mid-range where component wear starts to become a factor.
Suspension — 0.5% of failures
Suspension issues account for 0.5% of MOT failures on 1968 Jaguar 3.4/340 models. Suspension failures typically involve worn bushes, leaking shock absorbers, broken coil springs, and damaged suspension arms. These affect ride quality, tyre wear, and road holding. Typical repair costs: £200–500. Pre-MOT check: Look for uneven tyre wear, listen for clunking over bumps, and check if the car pulls to one side. A bouncy ride suggests worn shock absorbers. Visually inspect coil springs for cracks.
Brakes — 0.3% of failures
Brakes issues account for 0.3% of MOT failures on 1968 Jaguar 3.4/340 models. Brake-related failures include worn brake pads, corroded brake discs, leaking brake lines, and faulty brake servos. These are safety-critical components — any brake deficiency will result in an MOT fail. Typical repair costs: £150–400. Pre-MOT check: Listen for squealing or grinding noises. Check brake pedal feel — if it feels spongy or goes to the floor, have the system inspected immediately. Look at brake pad thickness through the wheel spokes (minimum 3mm).
Steering — 0.2% of failures
Steering issues account for 0.2% of MOT failures on 1968 Jaguar 3.4/340 models. Steering failures include excessive play in the steering wheel, leaking power steering fluid, worn track rod ends, and damaged steering rack. These affect vehicle control and are closely related to suspension wear. Typical repair costs: £150–600. Pre-MOT check: Check for excessive steering wheel play (more than a few inches of free movement). Listen for whining from the power steering pump. Look for fluid leaks under the car near the front wheels.
