How to easily install Rear Main Seal on Ford 4.0

How to easily install Rear Main Seal on Ford 4.0

Had to do the rear main seal on my 2004 Ford Explorer rebuild project. Never done one before, so thought I’d show you what I did after watching a few other videos. Those video’s didn’t quite give me enough detail to be super confident on this, so I hope this video helps you out with good advice. Be sure to check out Part 2 shows if this was successful or not.

I’m happy to do my best to answer any questions, but keep in mind this was my first time doing this, so I am by no means an expert.

FYI I ordered a seal kit from someone online and as I mentioned in the video the rear main seal was the wrong one. A couple other pieces in that kit also weren’t right. I ordered online and wish I would’ve called the company to verify I had the right kit before ordering. Do yourself a favor and do that! Will save time and money! The Fel Pro seal was around $20-$30 at my local O’Reilly’s.

How far do you push the seal in ? All the way until it stops ?

Seems legit dawg. So many videos don’t show the necessary details of the actual seal install yet the thumbnail says how to . I see that you explain the details and show exactly how so thanx.

My 4.0 ranger has a rear main seal leak. Just removed the flywheel and am about to remove the seal. Great video

Getting ready to do my 4.0. How did everything turn out? On the seal, and timing chains, etc. What timing chain kit did you use?
