In spite of what others have said, I've heard and read good things about East Coast Gears.  I'll have to check to see what was put in the front of the D60, but at one point he was going to use Nitro gears.  However, my nephew said to stay away from them as one set he get were not finished well.

What's the problem with factory gears?
Are they too expensive?

I've had a Yukon R&P since I split my carrier in half back in the mid oughts.
They seem to hold up to all the punishment I dish out.

Ol' Paul Nelson set them up for me.
All i did was let them cool in the first few hundred miles, and change the fluid at about 600.

This post was updated on .
I was just asking for opinions on sources. I will be doing the setup, just like I did mine. I may call Kool Ford and see what the parts run there. I did suggest he might want to consider a different ratio since we have go into it, current is a 4.10, I suggested maybe 3.73 since it's a Powerstroke and he doesn't do any real heavy towing with it. Darth does quite well with a 3.55.

Factory gears NLA from Ford, any ratio.

Most of the trucks I had were 4.10’s.

I really like the 3.55 in my truck.

When I bought the D60 with 4.10's I thought about going to them all the way around.  But the math just didn't work.  Even with the ZF's overdrive it was still going to be turning too many R's on the highway.  And, the 3.55's work nicely for towing in 4th.  I like them.

It's even nicer with an OD gear, Darth is turning 1500 rpm at 55, that is between the E4OD overdrive ratio and the lockup converter.

Ok, update on the rear disc conversion. All parts ordered, new wheel bearings for the left side, new 3.73 gears and installation kit, and due to (a) the rust on it and (b) the fact that it has to come off to do the ring gear, a new tone ring for the ABS/speedometer. He was going to order some drain plug kit for the cover, I told him a nice hex socket pipe plug in the bottom of the center casting would be better as it will drain it fully.

Going with 3.73's should help him a bit on MPG.  Does this thing have the speedo gear or, more likely, the electric sensor?

Electronic speedometer, uses the ABS signal to create a speed signal for the PSOM, which outputs a speed signal for the PCM.

With the PSOM you can reprogram for the new gears?

Gary, since it picks up the teeth on the tone ring (120 on a 10.25") the only time you really need to mess with it is if you go to different tyres. Rear gear changes do not affect the count.

Ok, update on this, left side is now done, had some issues getting the runout the rotor in tolerance. But both sides are done, and for my next trick, ring and pinion along with tone ring and bearings.


Drain plug in bottom where the low area of the casting is, 3/8" NPT and a nice hex socket plug.


And the fun begins, differential is out, if the bolts I bought will do it I will be able to persuade the companion flange to let go of the pinion splines.

My next major project was to be a rear disc conversion on 'The Beast'.  The reasoning was that I knew that one rear brake was screwed up, and to do any work on the rear brakes requires pulling the axle.  My thinking was that the conversion (which from sales literature sounds really easy) would save me from ever having to pull an axle after that if I only had to install new brake pads.

I was looking at the ruffstuff kit for my Dana 70U rear.

After reading your right up, I'm rethinking this project.  Maybe I'm better off just keeping (and fixing) the factory brake setup.

One question - I didn't understand where the water in the differential came from.   Was the axle left out in the rain with the axles pulled?

Brandon/Bruno2 has been telling me that the E-Series vans had a disc brake setup and that it may be a bolt-on for our trucks.  He's supposed to be researching it and will report back.

As for water, is the vent hose still on the axle?  There's a hose from the brake junction block that is supposed to go up and clip to the frame.  But sometimes it gets old and breaks off, allowing water in.  You can see it in the illustrations on the page at Documentation/Driveline/Rear Axle Vents.

Maybe for the heavier trucks, but not for 150s.  That's the swap I did.

The E-series still used the Dana rear axles, the one you have to pull the axle to get the hub off. Baddog8it, your truck may have the Sterling, 1985 was the change year.

The water could have come from the truck it was pulled from, or sitting around first in John's yard then on my trailer. The vent hose was broken, but the nipple was plugged with crud.

So far, one of the differential side bearings is pitted (new ones in installation kit) and the pinion bearings feel  rough when turning it.

Today, I will see if I can coax the companion flange (Ford's term) off the pinion.

"coax" is a kind word for a B*H and a chunk of brass bar stock?

I know nothing about getting caliper hangers on a Dana axle.
But I DO know that van frames are much narrower than pickups, so you have to reweld the spring perches and shock mounts.

When I bought my Horrid Fate 'Pittsburg' puller I never imagined how handy it would be for many things.

It was a great deal.
