All T-Type (TC/TD/TF) problems All workshop issues

Common Chassis and Suspension

Leaf Spring Fatigue

Symptoms

The car sits lower than normal, particularly at the rear. Ride quality is harsh. The chassis bottoms out over bumps. Handling feels wallowy and imprecise.

Cause

The half-elliptic leaf springs lose their camber with age and fatigue. Seventy years of use flattens the spring leaves. Broken leaves are also common, check by inspecting the spring pack from underneath.

Fix

Re-temper and re-camber the springs, or replace with new spring packs.

New spring sets are available from specialists.

Cost: $300-$600 per pair for new springs.

Re-tempering existing springs: $200-$400 per pair.

Oil Leaks, Everywhere

Critical Engine, XPAG/XPEG (1,250cc/1,466cc Inline-4)

Low Oil Pressure (Worn Bearings)

Oil pressure drops below 40 psi at cruising speed when warm, or below 15 psi at idle. A knocking sound from the bottom end, particularly under load, confirms the diagnosis.
