At over 60K miles, regardless of the owners manual I would want the transfer case and rear diff serviced, probably trans too.

 

Transmission I understand, that fluid is used for cooling, actual power transmission through the torque convertor, and hydraulic operation through the valve bodies. But I've never really understood the need to change fluid in the diffs or t-case. Those are both very simple items and the fluid is pretty much strictly used for lubrication. I've run a couple of vehicles to over 200k miles and never touched the diffs or t-case, and never had issue.

I agree though, an ounce of prevention is worth a pound of cure. Perhaps metal shavings could be a problem? Believe the oil in the diffs and t-case is synthetic.

 

To me because of heavy towing I change mine.


Normally, you are right. May never change them on a 1/2 truck.

 

Couple of items to maybe note or negotiate in:

Block heater
Supplement heater? Doubt they'd add but be good to know
Some type of bed liner
Prep package in bed

Also, if there is a vibration dampener on hitch drivers side, it probably went in for hop/vibrations at 40mph or some specific speed. Not a bad thing but gives you history

 

I've had to replace Brakes on my two trucks in the 60,000 to 80,000 mile range. But I tow a lot.

Batteries are almost always shot by 36 months

Front Bearings on my 2011 needed replacing at 105,000

Coolant is good for 105,000 and Tranny fluid for 150,000 but if the truck was under Severe Service ( ie trailer towing or extreme cold) they usually cut those intervals in half. Meaning both could be due for flush at 60-70k

 

I went and looked at the truck after hours last night (I don't like sales people)..

-Minor hail damage on the roof
-shocks looked to be the originals
-a few minor chips in the paint nothing major
-fenders, hood, tailgate, and bed all looked straight no visible signs of a wreck
-tires looked new
-bed was in real good shape
-overall in decent shape

I may go back for a test drive haven't decided....I'm a little concerned with 64k miles on a 2015 just a gut feeling I guess.


Thanks again for all the great info I am learning a lot here..

 

Not to split hairs but you won't find an aftermarket primary radiator for a 6.7 powerstroke for $168. I just installed one for a 2011 from Carquest and it cost approximately $50 less then the Ford one. I could have gotten the Ford one from AutoNation but they are VERY hesitant to ship a radiator as they very often get damaged. The aftermarket one has a limited lifetime warranty

 

Check rockauto.com. I just selected a 2015 F350 diesel. Screenshot:

 

Wow, interesting find! I guess I'm too paranoid to trust something that has that big a price difference with a competing aftermarket product but who knows...it might be just fine.
