Parts for your 2018 Ford Transit-Oil seals

2018 Ford Transit Oil Seals

Oil seals are absolutely fitted to the 2018 Ford Transit. Technical sources including the Ford Workshop Manual for Transit (engine Section 303-01, transmission Section 307-01 and driveline/axle Section 205-00), Ford ETIS/Service Info, and the Motorcraft parts catalogue all list multiple oil seals for this model, such as the crankshaft front seal, rear main seal, transmission input/output shaft seals, driveshaft/axle seals and differential pinion/axle tube seals.

On a 2018 Transit, oil seals keep engine, gearbox and diff lubricants where they belong, while letting shafts spin freely. Think of them as tidy gatekeepers—preventing messy leaks, protecting bearings, and keeping dust and water out. Whether it’s the 3.7-litre petrol, 3.5-litre EcoBoost, or the diesel variant, every engine relies on a front crank seal behind the harmonic balancer and a rear main seal at the flywheel/flexplate end. RWD models add diff pinion and axle seals, while the 6-speed auto has input and output shaft seals. FWD/AWD variants (where fitted) use transaxle driveshaft oil seals.

• Common seals on Transit: front and rear crankshaft, camshaft, transmission input/output, transfer case (if equipped), differential pinion and axle seals.
• Typical symptoms: oil spots under the van, a weep around the crank pulley or bellhousing, misting on the diff nose, or fluid on driveshaft flanges.

Oil seals aren’t a scheduled replacement item
