Hi everyone,

My 2003 TD5 Defender 110 has recently developed an alarming issue. While shifting up to either 4th or 5th gear, it feels like the tail of the vehicle is kicking out to the right (feels like a mini fishtail). I just took it up to highway speeds for the first time in a while and it will intermittently pull/yaw/wobble laterally and somewhat violently.

Tire pressures are good, and a quick visual inspection doesn’t reveal any apparent issues with springs or suspension.

Any ideas?
