Dimensions: Click here for dimensions. Check shape, size, number of bolts, level check hole location, axle rotation, vent if any, and clearance.

Because the Dana 44 differential has so many uses and variations, read this pdf file on PML Covers for Dana 44 differentials for more information on what to check before replacing your stock cover.

The Dana 44 differential is found on many vehicles beginning in the 1940´s and is still used today. For example, Jeep CJ 1941-1975 rear ends and Ford Bronco 1966-1979 front ends are typically Dana 44s. There are several versions of Dana 44 differentials so please check your vehicle carefully to verify shape, number of bolts, clearance, and level check hole location.

Do not use this cover on: 2009 and newer Jeeps or GM front ends. In 2009, Jeep changed the design of the rear axles and added a vent so a PML cover will not work on newer models.

Using on Front End

If you are planning to use this on a front differential, be sure you have enough room in all positions. The steering linkage moves forward and backward (in addition to side to side) as you turn the steering wheel. Reference this cover's dimensions.

Drain Hole, Fill Hole, Level Check Hole

This cover has three holes. The bottom hole is a drain hole. The plug at the top is used to fill the differential. The one on the side is left open when filling to let you know when the differential is full. Once oil starts to drip out the side hole, it's full.

Comparing Dana 44 Covers

Be sure to compare the number of bolts, shape, level check hole location to your stock cover and check if you have clearance for a larger cover.

Sway Bar On a Wrangler

Some vehicles have a sway bar ½–inch from the stock differential cover. Wrangler will need to be lifted or the sway bar moved or modified. Sway bar too close as is to accomodate a larger aftermarket rear end cover.

2008 Wrangler

MBRP installed this cover on the front end and rear end differentials of their custom Jeep 2008 JK Wrangler Rubicon. See a slide show of the installation. MBRP has lifted and modified this Rubicon. On a stock Jeep, the sway bar is likely to hit a deeper cover.
