Is anyone around the southeast Nebraska, northwest Kansas, southwest IA or northwest MO and expert at rebuilding a differential and installing a ring and pinion? Mine blew out last year and just LABOR to rebuild it (with me just bringing the differential in by itself) is over $350. Add the rebuild kit that ranges from about $130-$160 to that and the price continues to climb. I have a ring and pinion to install, but am not ready to drop another $500 into a piece that I had done just a short 5-7k miles ago. The trans-loc unit is still good, but the bearings etc and ring and pinion are what need replaced. I'm not afraid of doing the work, I just don't know how, or even if I have to tools to do it. I prefer to have an "teacher" there to educate me on how to rebuild one.

Any takers???

The guy that rebuild my 5-speed can do differentials. I asked him about doing a gear swap and I think he quoted me $100 plus parts. He is in Des Moines and is Lincoln transmission Technician. He has a ~12x24 shop in back of his garage dedicated to his side jobs of rebuilding transmissions.

I don't know how well this would work for you when you would need to make 2 trips, but I thought I would mention it.

That's a start. It's about a 3 hour trip, one way, but maybe that could be arranged during the club clash timeframe. It would give me a good excuse for going out there for sure! LOL!

Did you check with Lincoln Clutch and Brake?

Thanks for the heads up on that Thomas. They quoted $140 labor which is MUCH BETTER than the $350+ I was quoted from another source!

What would you guys recommend for the lubricant in the differential. I did some searching last night and came up with about 10 different answers.

Anything 75W-140 Synthetic (Mobil 1, Royal Purple, Motorcraft, Amsoil), and possibly 1 bottle of Motorcraft Friction Modifier if the clutches start to chatter.

I thought friction modifier was required.


I was told 80w90 by FRPP for the FRPP pumpkin I got new years afo.

Personally, I'll be going with Redline synthetic gear oil. I'll have to check again (multi-tasking on the phone now too) on the specs, but I believe that the friction modifier is already added to that. I've had great results with Redline products.

Some synthetics come with the modifier already in it, like Royal Purple and Amsoil. I was going by what Alan has recommended over on TCCoA on the fluid weight, and what I've learned with Explorer 8.8 IRS.

The Redline 75w90 and 80w140 both have the friction modifier added, however, depeding in the specific application, additional modifier may be required.

The 75w90 would be the ideal for typical day to day type driving with some part-time racing in there. I used 80w140 and it is super thick. I'll be going back down to the 75w90 in this differential.

I think I have additional technical data sheets at home for the gear oil. I'll do some more digging to see if I can find them later.

Here's the additional information that I was thinking about...had it, just had to find it on my "work" computer...haha...

Go on the cheap. Used motor oil and two bottles of friction modifier. Add a tub of Vaseline if you want to thicken it up some. You'll be golden.

The bearings and races will last much longer if any synthetic 75W-140 is used. The Motorcraft or Mobil 1 is what I put in them after I rebuild them. All the newer Ford Differentials use this for a reason. Especially on the IRS Explorers(2002 and up) and Expeditions/Navigators(2003 and up) due to their higher operating temperatures and Aluminum housings....
