132K isn't much for the inline six, 4cyl might be due for an overhaul.

Of course things like towing and larger tires put more than normal stress on a drivetrain. If regular maintenance was performed any Jeep with 132K should be running just fine.

I have to agree with cjensen, milage means nothing compared to history.
I rented a Rubicon in Hawaii with under 50K on it that was already burning oil, steering was loose ,shocks were leaking and generally showing signs of heavy abuse on the entire drivetrain.
