Dodge replaces rear axle seals twice and I have replaced RR seal recently. Now the LR seal is leaking. Is this unique to my 04 2500 Diesel? Reading some of the threads, I was peeked to check the differential vent. ??? Have others had a similar issue.

 

1. Vent Bad
2. Axle bent
3. bad bearings

 

Not likely that both axles are bent or bearings on both sides are bad... the bearings on the one wheel I had apart were perfect. Haven't had opportunity to check the vent yet.

I appreciate your help.

 

I checked the differential case and I can't locate any vent! Brake line connections (banjo type fitting) and emergency brake cable and and what appears to be an electronic sensor on the top left. I have no idea what that might be. Diff. is the 11.5 inch ring gear. Where is the vent supposed to be? Can anyone help.

 

the vent should be on top of axle left of pumpkin....
