Default Airtruksrus rear end disc swap

Started this on the Cardomain page and thought i should show off the construction project. As where it sits for now, the welding and cleanup is generally finished and getting all the parts fitted back on to the main axle housing as it will be situated on the frame.

This is where it started, a rear end located near Portland from a wrecked 2000 Ford Explorer with 3:55 gearing, 31 spline axles and discs that are about 2 inches bigger diameter that fit nice inside the 16" rims currently on the truck. Came with the shocks, springs, torsion bar with 1 link, and an additional shock mounted on the front of the differential housing. Looks like it can be adapted to fit up to the torsion bar on the other side to provide some better stability.

The internals appear to be in good working order but eventually get it replaced with a trac loc assembly for the 31 spline shafts.

The housing was a bit beat up on one side and was an easy fix. The brake pads for the discs and the ebrake seem to have enough surfacing left and will get them changed out as time goes on.


The new leaf spring supports had to be ground down a bit to fit the heavy duty axle housing.

Came out almost perfect but had to put a 45 degree bevel in order to get the mig welder to give a complete fillet.

Hell of a job for a first time mig weld, had about 30 minutes practice on some scrap before making this permanent.

did some grinding and cleaned it up just before painting.




This is where it stops for now until the truck gets pulled into the garage to start doing the swap, have a small ranger meet in seattle on Oct 2, don't want to miss it.

I have a short bit of time before my job sends me out again on location. As for the progress, I managed to find a couple more weak parts and this time it would be the rear u joint and possibly 1 or 2 of the bearings in the T5 are really getting sloppy and can move the driveshaft up and down on the output shaft. Probably where the vibration had accelerated the wear and tear during the 1,000 mile trip last weekend. It started vibrating around 50mph in 4th and 75 in 5th, and only got nastier as the trip went. There was one part of the trip that I could see how fast it would climb out of the gorge going west to Ellensburg, Turns out it had no problem with acceleration in 4th and was able to maintain 85 to 95 up the steep hill but had vibrations all the way up the long hill, was fortunate to not end up on the side of the road with a blown tranny.

The bed of the truck gets put in the backyard tomorrow.

Got set up in the garage and did a fairly thorough inspection on the drivetrain where the rear u joint looked like it blew out one of the bearings and would move off center. Would have had to do the same thing and remove it since the attachment bracket for the Explorer rear requires it to be changed out for the larger bracket.

The plates for the shocks need a bit of cleanup but should be ready for bolting up.



If all goes well, the mustang club in town gave me an invite to their day with the dyno, keeping the fingers crossed.

Was up till around 3am working on it last night, decided to cut it short tonight. just need to finish up with corrosion control on the shock plates.



Anyone looking for a spare 7.5 rear end, complete.

Got the Expo rear rolled under and bolted on with the u bolts temporarily until i can track down some 8" long grade 8 bolts.




Looking great with the discs, hope that the rest of the assembly goes smooth. Will have to finish most of the final build when I get back from Cali.

Was able to get a hold of 4 of the bolts, was able to get a perspective on how the shocks were going to clear the frame and if the torsion bar was going to have any issues. Unfortunately the torsion bar might be too close to the left shock and try a couple of different options.

Finally got back to work and knocked out quite a bit over the last 3 days.



Corrosion work done, paint applied, axles reinstalled, differential reassembled, brakes bolted on/bled and all the support bolts torqued down.



The brake lines from the Explorer were just a bit on the short side and tweaked the bracket to allow for full travel.

Picked up the new ujoint and found a slight problem with the compatibility. The Ranger has a smaller width than the Explorer and requires an adapter. The friendly folks down at Parts Plus have the catalog to get it on order this week for a 354 to 270 size ujoint. Probably make it easy next time and have the driveshaft converted over to make the search for a ujoint easier.

Looking at extending the solid link for the sway bar to get the right length, needs to be around 16".

I am one lucky son of a gun...

Besides getting the solid link extended ...



and getting it hooked up to the frame rail, may still have to move it up about another inch or so,



I just happened to get over to "Better Off Road" to get the right size pipe to do the extension and found one of these sitting on the shelf -



A 31 spline 8.8 trac loc differential (125$), definitely a way to remember Black Friday for years to come. The only problem is that the other differential was just put back together, sealed up and topped off with new fluid. Just a simple matter of draining and dissassembly, all over again. Once this gets put in, little chance of ever having to mess with the rear end for a very long time...

The other bit of great news is that i was up in Bellingham to drop off the drive line to get modified, thinking that no one has the adapter ujoint anywhere, and they just happened to have one sitting on the shelf. Almost had to fork over $135 for the welding job with the new ujoint. They only charged $35 for the new joint and install.

I'm lookin for another excuse to get out to the next meet. It's gonna be a blast driving it around and not having to worry about blowing out the ujoint trying to do a double burn. I'll bring some wheel chocks and let it rip...
