Yes, this is the single most common reason a Shogun fails an MOT.
It is one of the strongest tow cars of its era, which is exactly why so many are worn.
Yes, mechanical parts are still widely available and reasonably priced.
The five-speed automatic transmission requires a fluid and filter change every 45,000 miles or four years. Neglecting this schedule frequently results in harsh gear engagements, torque converter shudder, and premature internal wear. It is critical to verify this in the service history and ensure genuine Mitsubishi ATF SP III was used.
The rear suspension eccentric camber bolts frequently seize solid inside their bushes due to corrosion. While not an immediate MOT failure unless the bushes tear, it makes four-wheel alignment impossible without cutting out the old bolts with a reciprocating saw and replacing the entire rear lower control arms.
