JY Ranger 8.8

[RoamingCanuck]

I pulled a replacement 8.8 from a junkyard with 4:10 gears in it, from the door it said it was open diff. But I broke the cardinal rule of JY pulling, take a picture of the OEM Vin panel with all the vehicle info on it. It was pouring rain, I was miserable but it was a perfect complete axle to replace my ailing one in my ranger so I had to have it.

My question is do the drum brakes change at all over the years? I know for sure the donor was 98 or newer but I'm not certain of the exact year. I see various part numbers from Raybestos and AC delco on rockauto based on year.

However I see that the Ford part number BRDF16 for drums is present in every year from 97 up to 2011 so I'm not really sure.

I want to put all brand new brake hardware on the axle before I install it so that I know its 100% good. The truck sees a lot of km towing a trailer so I don't like to risk it on brakes.

The only differences in brakes are 9" or 10" drums, take a drum off and measure the ID and that'll tell you which you need, I think most 8.8's had the 10" drums though but as with all Ranger parts there's no definite...

Its for sure a 10" I was just concerned about the other parts like combi kit and such

A lot of parts stores have the brake parts all sorts of confused sometimes, they have listings for Dana 28 parts through '97 when they weren't used past '89...

If you want to be sure to get the right shoes and hardware, get parts for a '94 Explorer as they have 10" drums which take the same pads as the Ranger 8.8's, they just have a different backing plate to go with the bigger axle shafts.

The only thing that changed somewhere around '98 or so is the hole in the center of the brake drum and the center stub on the axle shaft changed sizes, I think the new ones are bigger than the older ones but I don't have anything to check against as I wasn't paying attention when I had my '00 Explorer apart...

Would it matter that its a Ranger 8.8? 28spline

the 10" drums are the same between the Ranger axles and the Explorer axle, everything but the backing plate interchange. I say Ranger axles because the 10" drums were used randomly it seems (I think there has been a pattern found, I just don't remember it) on both the 7.5 and 8.8 axles, most 8.8's came with 10" but some with 9" and the other way around on the 7.5...

Good old random Ford.

My current axle is the 9" brakes on a 7.5" rear end, new one is 8.8" rear end and for sure 10" drums. I put them beside eachother and the 8.8 drums are bigger. I did the upgrade mostly for the 4:10 gears and the larger brakes. Makes a difference towing my trailer.

If you want to get real crazy - put Aerostar rear drums on it. They are 10" and finned = better cooling when loaded/pulling trailer.

Be aware: Rear 10" drums will lock up faster than 9" ones did. Not a problem if you have ABS, but can be exciting on ice when unloaded if you don't...

I do have ABS, but thankfully its a summer only vehicle anyway. Its literally just used for camping either towing my pop up or bush camping with my hammock.
