4.0 durable

[BrokeRecord]

I put 155,000 on my 99 4x4. Changed oil every time before stick showed it low on oil. One set of ball joints at 110,000, one set of plugs. Bought my 07 4x4 because I had the cash and just retired. Ole Whitey ( no dents and very good interior) lasted one day on the used lot. Now both of us are happy campers.
You take care of the 4.0 and it will take care of you.

I saw one at the bone yard today with 329,000 on the clock. The motor was out (sold) and written on the truck was "good motor & trans". I think that with proper maintenance and not too much abuse the 4.0 may go forever.
