Based on your statement of 60km, I am going to assume you are in Canada ??

When the front differential was refilled, did they refill with synthetic hypoid gear lubricant per SSM 45087:


SSM 45087 - 2009-2015 F1504x4 Front Pinion Bearing Damage


If pinion bearing damage is noted during the repair of the Front Axle on 2009 -2015 F150 4x4 units operated in severe cold climates. Use Motorcraft XY-75W85-QL Synthetic Hypoid Gear Lubricant upon reassembly and fluid fill. The lube will offer better pinion bearing lubrication in severe arctic conditions. Only a small number of units operated in the most severe climates will benefit from the using the synthetic lube. Do not replace thelube unless you have identified a concern with the pinion bearing (or as perrecommendation of Ford Hotline)

Note: starting in 2017 this is now the recommended fluid for all climates

My 2016's sprung a leak. Fortunately it was spotted by an "oil changer" before it lost too much fluid (he saw the gasket was starting to leak). While I was waiting to get it in for a warranty repair I felt it was running a bit rough (or it could just have been my imagination).
