My jeeps have never needed anymore fixed than other vehicles Ive owned ..... but they certainly need some bits maintained/replaced more often.

Lotsa washboard road use down here makes a mockery of the, back the front, trailing arm suspension used as the TJ & XJ front suspension ...
Suspension rubber life is shorter ... but its the price one pays, in having a live front axle, passenger vehicle - that meets govt crumple rate requirements.

The barely adequate cooling system always needs to be top notch condition - to be worry free ... so gets more luvvin than a homegrown vehicles cooling system. Again its not a fault as such ... its what you get for buying a vehicle sold here rather than designed for here.

Premature sensor failures due to engine bay temps is another PITA ... but theres ways to improve that situation.

All up tho, and just IMHO .... buying a 2nd XJ and tidying it up as a longterm DD is still better value than buying the midsized, overpriced blingfests, in toyota and nissan showrooms.
