Pre-MOT Inspection Checklist for Jeep Wrangler Sahara Unlimited Owners

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

• the lights — “registration plate lamp(s) inoperative in the case of multiple lamps or light sources”

  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 windscreen — “windscreen damaged”

  Check the driver’s side of the screen within the swept area for chips and cracks; anything larger than 10mm in the driver’s central view is a fail. Most chips can be resin-repaired for far less than a new screen.

• the suspension joints — “track rod end ball joint dust cover damaged or 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.

Derived from the DVSA failure strings testers recorded for the Jeep Wrangler Sahara Unlimited. A check that finds nothing means the item is likely fine, not that the test is guaranteed.
