Rear main seal on Ford 02 ranger.

[Dabba]

So, my mother has an 02 ranger she bought less than two years ago. Recently it started having an oil leak. For whatever reason my stepfather believes the truck is shot, so assuming it's something bad like the rear main.. How hard is it to replace? It's an auto. I assumed it would be something like unbolting the tranny and sliding it back to get at the seal, but I'm not too familiar as I've never had to do it on my CUCV (though i've read about it) and I'm not very familar at all with new fords (or old ones for that matter)

Thanks guys. I just dont want him to sell or junk the truck if it's something that can be done in the driveway.

I'm no ford guru but given that it's an 02 I would guess one piece RMS. In that case if the transmission has enough room to slide back 4-6in I don't see why you couldn't do it just as you described.

4 banger or v6?

The 4 bangers valve covers will leak, run down a drain hole in the block and look like a rear main.



Otherwise yea, pull/drop trans redo seal. Easy job, but time consuming.

Worst case the crank seal area is grooved and will need a speedi sleeve....still not a deal breaker,,,just adds a little to the cost of repair parts...

Sorry guys, Finals have me running ragged. Speedi sleeve?

I think it's a 6 cyl. I heard about the top end leaking and draining down the back, does that happen with the sixes? I dont blame my stepdad for being fed up, we just had a decent ice storm. The leak doesnt look that bad, well sitting, and she still drives it around. I think Im just going to tell him to wait until spring and ill help him tackle it in the driveway.

The original seal can wear a groove in the crankshaft where the seal lip rides against the crank.... if you stick another seal in without correcting the groove..chances are the seal will start leaking again...

A speedi-sleeve can be installed on the crankshaft to "repair" the seal worn surface....

Problem is.... they cant be used on all cranks as the sleeve needs to be driven over the end of the crank..and some cranks are designed with a flange or slinger that is larger than the seal riding surface meaning there is no physical way to get the speedi sleeve over the end of the crank.
