Common Problems with the
2009 Morgan 4/4

From 2009 until production ended in 2018 the 4/4 used the 110bhp 1.6-litre Ford Sigma engine - Morgan's own final specification for its longest-running model - retaining the traditional steel chassis, ash frame and sliding-pillar front suspension to the last car.

What changed for 2009

  • •110bhp 1.6-litre Ford Sigma engine fitted from 2009 to the end of production
  • •Final era of the 4/4, which ended in 2018 after 73 years of near-continuous production
  • •Hand-built steel ladder chassis with ash-wood body frame and sliding-pillar front suspension
  • •No airbags, power steering or ABS - a traditional MOT and road car to the end

Common MOT watch-outs

  • !Steel chassis and outrigger corrosion; check for ripples or creases indicating past accident damage
  • !Ash-wood frame rot at rockers, sills and door pillars on poorly stored examples
  • !Emissions and lighting faults on Sigma cars used only for short trips

All Known Issues

Ash Wood Frame Rot

SeriousBodywork & Rust

The 4/4's body panels are fixed to an ash-wood frame, and moisture trapped behind panels, under wings or around door sills can rot the timber. Soft rockers below the doors, damp sill boards and loose or dropping doors are the warning signs; post-1986 cars had factory Cuprinol-treated wood, but earlier examples are higher risk. Structural wood repairs are expensive and should only be undertaken by a Morgan specialist familiar with traditional framing.

Est. Repair Cost: £1,000–£5,000
Warning Signs:

Soft or spongy wooden rockers and sill boards, Loose or misaligned body panels, Doors that drop or stick in their frames

What to Inspect:
  • Press the cabin side padding below each door for soft wooden rockers
  • Probe lower A-pillars and rear wheelarch frames with a moisture meter
  • Look for blackened wood through access holes

Sliding Pillar King Pin and Bush Wear

ModerateSuspension & Chassis

Every Morgan 4/4 uses the traditional sliding-pillar front suspension that dates back to 1909. Its king pins and phosphor-bronze bushes need regular greasing; if the interval is missed they wear, causing play in the front hubs, heavy steering, a shimmy through the wheel and uneven tyre wear - and excessive play is an MOT failure. Replacement means pressing out worn pins and bushes and re-setting the damper blades, work best left to a Morgan specialist.

Est. Repair Cost: £400–£800
Warning Signs:

Heavy steering, Steering shimmy or vibration through the wheel, Uneven front tyre wear, Knocking from the front suspension over bumps

What to Inspect:
  • Jack up the front and check for vertical and lateral play in the hubs
  • Ask for evidence of regular king-pin greasing
  • Test drive on an uneven road and listen for front-end knocks

Wing and Valance Corrosion

ModerateBodywork & Rust

Before 1986 Morgan wings were attached to the car and then spray painted in situ, so when the body flexed the paint cracked and rust formed behind the wing panels. Aluminium wings rolled over a steel wire can also suffer electrolytic corrosion at their edges, and the front valance can rust where it meets the bulkhead. Paint blisters around wing-light bolts and headlamp nacelles are the first warning; severe cases need wing removal and panel beating by a Morgan-trained body shop.

Est. Repair Cost: £600–£1,800
Warning Signs:

Paint blisters at wing edges and fixing bolts, White powdery residue at aluminium wing seams, Rust streaks below the wings and at the bulkhead valance joint

What to Inspect:
  • Inspect wing edges, headlamp nacelles and wing-light bolts for blistering
  • Check the front valance where it joins the bulkhead for rust
  • Look underneath where the bulkhead meets the valance for corrosion
