Pre-MOT Inspection Checklist for Jeep Wrangler Sahara Unlimit Owners
These checks follow this Jeep Wrangler Sahara Unlimit's own most-recorded failure strings, starting with what a tester is most likely to flag on a Jeep Wrangler Sahara Unlimit.
-
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 coil springs — “coil spring fractured or broken”
Look up inside each wheel arch with a torch, all the way round the spring. A snapped spring usually breaks at the very bottom coil, where a quick glance will not reach.
Derived from the DVSA failure strings testers recorded for the Jeep Wrangler Sahara Unlimit. A check that finds nothing means the item is likely fine, not that the test is guaranteed.
