Common Suspension and Steering
Worn front trunnions and kingpins
Symptoms
Clonking over bumps, vague steering, uneven tyre wear, play in the front wheels.
Cause
The P1800 uses trunnions (kingpins) and bushes, not ball joints. They wear, especially if greasing has been neglected. The design is agricultural but durable if maintained.
Fix
Jack up the front, check for play by rocking the wheels.
If there's movement, the trunnions need replacing.
It's a big job, press out the old ones, fit new bushes and kingpins, ream to size.
Most people take it to a specialist.
Budget $500-1000 including parts and labour.
