This Dodge rear end cover features drain, level check, and fill holes for easier maintenance. Just below the fill plug, is the level check hole. You fill until the fluid comes out of that hole. Plugs are provided for all three holes. The drain plug is magnetic.

Temperature Sending Unit Optional Machining

The cover has a location on face that can be machined for a temperature sensor. The option to have the cover drilled and tapped will need to be ordered over the phone, not on-line, and there is a machining charge. The temperature sending unit will stick out perpendicular to the face of the service. Please call to order or for more information.

These pictures are from Paul who installed a PML differential cover and low profile transmission pan on his 2006 Dakota, 4x4, 4.7L (PML part number 11078). Thanks to Paul for sending us pictures. See more pictures on our facebook page. You do not have to join facebook to view.

PML Differential Cover Installed on 2012 Ram 1500

Dodge began adding a pan hard bar and a sway bar behind the stock cover around the 2009 model year for Ram 1500 trucks. We have heard that it is a very close fit with the bars so please measure before you install.

Images courtesy of www.ramforumz.com. According to the posting, the axle's fore and aft movement is controlled by the upper and lower control arms, so the 3/8 inch clearance is not a problem. You might need an account to view the pictures and read the post.
