Internal Oil Line, Removing and Installing

Internal oil line, removing and installing
Special tools and equipment





- 3381 Oil line installer
Faulty O-rings on the internal oil line allow ATF to enter the differential. This then becomes overfilled and oil will seep out of the breather holes of the differential.
If an oil line is removed, it should generally be replaced.
The oil line should only be inserted using 3381 Oil line installer. Otherwise there is a danger of the oil line becoming bent, which will cause leaks to occur.
