Advice for buyers
What should I look for in a used Jeep Wrangler 4x4?
Off road damage
Look underneath the vehicle for any ladder chassis damage or rust near to where suspension components are fixed since this can lead to an MOT failure. Also, make sure there aren’t clumps of mud under there: it can trap moisture and cause corrosion.
Excessive shimmying through the steering has been named as the ‘death wobble’ by owners and can, in some extreme cases, affect control. The root cause is a combination of worn suspension and steering components including ball joints, wheel bearings and anti-roll bar drop links. If you feel a shimmy, we recommend you get the car inspected.
As mentioned in the previous paragraph, the ball joint can wear out alarmingly quickly. Some have suggested that the protective rubber gaiter surrounding the sealed joint can perish within 10,000 miles, or less if the vehicle has lifted suspension. Budget for regular replacements.
Leaking axle seals
The differentials on both the front and rear axles, that help to send power from the engine to the wheels, can leak oil. This is a problem because, not only do you not want them to run dry, you also don’t want dirt to get in and ruin the mechanicals.
Interior rattles are part of the Wrangler experience, due to way things are easily disassembled for cleaning. An individual rattle could be caused by a loose panel that needs re-assembling correctly or something that needs tightening. Try lubricating rubber roof seals with an appropriate rubber friendly product, too.
If fitted, infotainment systems can sometimes have glitches that can go away if you switch the car off and then on again. If that doesn’t sort it, then you might have to get an update from the dealer. Later Uconnect systems can be updated over the air.
