Changing rear seal

I noticed my rear seal is not doing too well these days. There were some spots on the driveway over the last 2 weeks, but I just attributed that to my 89 Bronco which is notorious for leaking. After taking photos for Bryan today, I found it was the Ranger.



I've never changed the seal before. I imagine all I need to do is remove the cover, let the fluid drain out, then put the new seal and the cover back on with some rtv sealant in between. Is this correct?

Here's what I need to know -What kind of fluid, and how much of it will I need? Where do you put the fluid in? What's the part number of the seal that I need? I think its an 8.8 rear, but I'm not sure. It's an Edge model with the 4.10ls in there from the factory.

No seal for the rear diff. The way its done from the factory is with RTV. Just make sure you get a good even coat or you'll have to go back and do it again.

^^^^Ditto.


You can buy a gasket if it makes you feel better though. The manual will tell you how much fluid and what kind to add.

The fill plug is on the front side of the diff on top. I think it's a PITA, that's why I've got a new cover with a drain and fill plug easily accessible on the cover coming in the mail soon =]

Yeah like l2en said its a PITA. I went to the local parts store and picked up one of those pumps that you screw onto the bottle. Made the job MUCH easier. I think it was like $6 or so.

Just kidding. Where did you find the cover, and what did you end up paying for it?

Do you just fill it with fluid till it overflows, or is there a point before that where you're supposed to stop?

Oh yeah... what should I use for the fluid?

don't forget the LS additive, I think the fluid is 80w-90. It will say gear oil. Then you need a small thing of LS additive. Fill it until it over flows.

Too bad you didn't say anything, I have a bottle of Ford Racing Friction modifier collecting dust in storage. I would've thrown that in the box.

Yeah it should be, it is at mine.

If you can't find the LS juice its not a big deal, your Limited slip just might not limit the slipping as well. If you do find the LS juice put it in first so you know you got it all in there as the the diff gets full fast.

Alright, I'll take the fan off, send it back to you, then you throw that in the box and send it back.

i dont think its that hard to get to the fill plug with a bottle of gear oil..
the front one is a different story tho


but if you use Lucas Gear oil you dont have to use any additives...

if you use Lucas 80-90 then you do not need that silly friction modifier.

I'd still probably use the friction modifier anyhow, just to be safe... or would the be a bad thing?

Also, this is the closest thing I can find to a fill plug. Is that it, and if it is, how do you get it out?

Thats it. Just stick your 3/8ths socket wrench in and turn it out. An extension would prolly work best. Righty tighty lefty loosey.

Hey once in a while ford makes things easy.

I actually thing it may be easier to change the diff fluid than the engine oil.
