Pre-MOT Inspection Checklist for Jeep Wrangler Extreme Owners

These checks follow this Jeep Wrangler Extreme's own most-recorded failure strings, starting with what a tester is most likely to flag on a Jeep Wrangler Extreme.

• the lights — “position lamp not working”

  Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.

• the wipers and washers — “wipers blade defective”

  Run the wipers with the screen wet: they should clear it in one sweep without smearing or juddering. Top the washer bottle up and check both jets hit the screen.

• the suspension joints — “ball joint dust cover severely deteriorated”

  With the car parked on level ground, rock the top of each front wheel in and out while someone watches the suspension arm. Clunks, or rubber boots split and greasy, are what testers record here.
