Explorer disc brake swap

So the ranger will need new brake shoes soon and i was loathing at how much i hate the drum set up. last trip to the junkyard i found numberous explorers with thier rear axles intact.

so i put two and two together and decided to swap over the disc brakes from the explorer. i have no physical urge to swap axles just the disc brake goods.

i know i will need the backing plate, caliper brackets, rubber lines, rotors (ill buy new), brake pads (ill buy new), calipers (ill get those new). what is to be done with the parking brake? and what would i need? even though the parking brake on my moms 03 xploder sport doesnt work worth **** i may not even swap it over...?

I am quite positive you cant swap the Explorer brakes to the Ranger. Unless you have a 31-spline FX4 axle

They make kits for the 28-spline disk brake swap. I dont know if the old fox body mustang kits will work or not.

Lol, if you want to swap over to the disc brakes, you could always swap the entire Exploder axle into the ranger. Its exactly the same width. By the way, the reason the brakes won't fit is because the flange on the end on the axle tube is different. A foxbody disc brake kit would work, but it would have to be for like 84 through 93, because the 94-98 shafts stick out further than the earlier models.

because i dont feel like it? local junkyard wants to much for the axle and there is no reason (other than the disc brakes) for me to swap axles. i doubt she will ever break the 28 spline anyway.

The leafs on the explorer are under the axle so youl'l have to cut the perches off and weld new ones on the top. Shock mounts also need to be moved. Ruffstuffspecialties has a kit with all the pieces that is wonderful.

if your a lowered truck yes because it will be like a 5" drop...

other wise you need to weld on new spring perch and shock mounts

the explorer axles already have the 'flip' kit on them. so you would just bolt it in.

If you look at your rear axel in line with your front, you will notice that the front is wider, and the rear is sucked in a little, about 3/4 of an inch each side. With the exploder axel, it should bring the rims in line with the fronts.

Atleast on mine it is sucked in.

I did the swap, welded on the perches and shock mounts. One of the best bang for the bucks ever. went from a 7.5" with 3.73's and an open diff to 8.8", 31 spline, 4.10's and a LS. Big boost over the regular acceleration. You will need new U bolts, and you will need to get new e brake cables for an explorer. Other wise it is all bolt in. Its SOOOO very easy. As for people who are lowering its a direct bolt in I believe. I can't comment on the shock mounts because I don't remember. Also you will notice that the rear brakes lock up before the fronts, fix for this is either A. the brake distruabution block from an explorer (emits less pressure to the back calipers) or get a proportioning valve to add into the brake line.

For the looks, I didn't notice a difference. Its less than an inch on each side so chances are you'll never even notice.

there is 1.2" difference in track width on a 2006, according to the owners manual.

i would like to do the explorer axle swap on my truck to gain the rear discs, 31 spline axles and the added with. i can see the difference in track width, to me it looks like more than 1.2" difference. the rear tires tuck so far under flares it looks funny.

it's hard to justify swapping a complete axle that only has 30,000 miles on it...! especially for one that likely has 3 times that many!
