Discussion:
The axle fill holes on some 2004 Dodge Truck axles may be located considerably higher than
the actual fluid level. Filling the axle until the fluid comes out of the fill hole will over fill the axle,
which could cause fluid foaming. When checking fluid level or filling a rear axle with fluid, you
must measure distance from the bottom of the fill hole to the actual fluid level. This can easily
be accomplished using a pipe cleaner or piece of wire. Make a 90 degree bend in the wire 2
inches from the end. The wire can then be inserted into the axle fill hole to use as a dipstick.
Measure the distance from the bend to the oil level, The fluid levels for the axles are shown in
the table below.

(HB) DURANGO
AXLE	FLUID LEVEL (measured from the bottom of the fill hole)	FLUID CAPACITY
8.25 Rear Axle	22 mm (7/8 in.) ± 6 mm (1/4 in.)	2.0 L (70 oz.) - SAE 75W-140 Synthetic

are not required.
