Rear Main Seal 6.2 Gas
 

It appears my 2015 F-350 (with 6.2 gas engine) has leaking rear main seal. I say "appears" because the leak is coming from the bottom of the dust cover, and nowhere else. Could anyone please tell me what I am in for regarding repairs? I really do not feel like doing the work myself (at 71 years of age) and asking what anyone has paid for such work at a dealership. I currently have 110,000 miles on truck so well out of warranty. Also, where might I find a good shop manual? Thanks much.

If the RM, the trans would need to be removed for access, If not the RM, possible a pan leak but more likely a seal.

Paper manuals like Helm aren't as common any longer with CD/DVD available but can be had. With internet service bay tech resources, CD/DVD is fading out..
eBay is a source for CD/DVD, possibly paper copy if you get lucky, or you could order a Heln book. Some of the other material offerings come up shy with info and illustrations but cover basics. If you have a task you need to perform, we can send you tech help info if you post the request..
