Oil leaks used Rubicon 2013 towed vehicle

I'm considering buying a 2013 Rubicon which is on consignment with a local Chevy dealer. It has a Smittybilt tow bar installed, so I'm pretty sure it was towed behind an RV. Odometer shows 70,000 but who knows how many additional miles it's rolled behind the RV. It has an automatic. Questions: what in the driveline turns when being towed? Why all the apparent oil leaks evidenced by oil at bottom of pan, valve cover especially on right side, and differential?

Thanks.

I could be mistaken, but I am pretty sure, tires, axles, differentials, drive shafts and transfer case.

As far as the oil leaks - i would have it degreased and take it on an extended test drive.

Not uncommon for folks towing to disconnect driveshaft (s).

can you post some photos? 12 and 13 models had some cylinder head issues.
the good news is Chrysler has extended the warranties on those heads.

when new wranglers are flat towed they need to be in park (auto) and t/c in neutral.

Itwould be a time consuming pain in the ass on the JK with stock ds.

the axles turn and beyond that, basically nothing.

transfer case goes to neutral, trans back to park.

When my dad towed his, he kept track of mileage for gear oil swaps, tire rotations, and unit bearings.


As far as the oil leak, sounds like the oil cooler is leaking, which is located in between the cylinder heads under the intake manifold and is known to crack and leak and then oil makes its way down the cylinder heads and to the bottom of the pan. I havent read of to many valve cover gaskets or pan gaskets leaking on the 3.6l compared to the old 4.0 where those were the first two gaskets to go.

The differentials(axles) can leak from either the cover gasket(cheap to take care of) or internal seals which cost a little more due to labor(the seals themselves are like 15 bucks a piece, just takes a bit to get to them).

I didn't say it was ideal. I know many who do that (on whatever RWD and 4WD vehicle they're towing).
