Got my replacement wheel bearing hub tuesday:  Got it all cleaned up, painted, modded for the 5/8" wheel studs, and installed!  Finished cleaning, painting, and reassembling my draglink:  As you may recall, my tierod has a few bends in it:
So, i got a new piece of tubing tuesday as well, and started tapping it!
Both done and installed!  Of note though, is that the steering ram is not yet connected. Thats the next project, which i hope to make some progress on this afternoon. More parts!  I started the reassembly of the D60. Greasing kingpin bearings:  Springless Kingpin caps from PartsMike:   and the passenger side is now complete  This is as far as i got on the driver side:  I picked up my wheel bearing hub, and the outer race fell out! Looks like the wheel bearing hub is shot, so im now sourcing a replacement. So since im dead in the water on the D60 i moved to the D70, but all ive gotten done, is the removal of my old, very beat, lower shock mounts  So i guess the next step will be to weld on new lower shock mounts, and then mock up my new caliper mounts. I have a line on a replacement wheel bearing hub for the front, which i hope to pick up sometime next week. Radius arms out:  The bushings were toast  ...and i decided to paint them. Color matched to the truck, which probably wont even be noticeable underneath it, but oh well  Both arms are reinstalled; no pics. Thanks to COVID, my steering kit is still backordered. Shocks are still backordered. Kingpin caps will show up tuesday, and my new rear caliper mounts are in a truck somewhere in CA, so maybe theyll show up at some point. So not much i can do, until some parts actually arrive. Ok ive got a small update. The D60 is stripped and cleaned:  My air leak was a rupture in the soft copper tube for the locking collar for the ARB. So thats out  The o-rings are not in bad shape...  ...but the new collar comes with the updated quad-rings, so of course they went in  ARB ready for reinstallation:  At this point, the ARB is back in and pressure tested; all is good. I have a growing pile of parts in the garage:  Im expecting 5(?) more deliveries before i have everything to finish the truck. One of those is my new springless kingpin caps, which i wont get until next week, so i cant reassemble the D60 just yet. So i tore into the D70 today. Apparently i ordered the wrong wheel bearing hub seals! Also, i need repair sleeves for the spindles which im currently researching (proving to be a challenge to find the right ones). Also, my caliper brackets are wallowed out and need to be replaced so it looks like im pretty much buying a whole new disc brake kit, once i can find one with the correct offset for my housing, which i am also having trouble finding. I may have to buy a weld-on kit, or try and make my own. So yeah, not much accomplished, and it looks like itll be at least another week, before i have all the parts required to finish rebuilding either axle. So now that im done with the electrical upgrades, the next step is to inspect my neglected axles. So, tuesday i got the truck up on jackstands!  Pulled the steering off so i could inspect the ARB. it has seen better days!  I am replacing the whole steering setup with the system the Boulder Proof HD Steering Kit from Broncoair. Unfortunately backordered for a couple weeks due to COVID, but ive got enough to do just yet that it shouldnt delay me anyway. So i took a look at the ARB, to see if i could find my air leak. Figuring after 15 years an o-ring was leaking. Well.....  ...the copper supply tube is ruptured, so that needs to be replaced. So the ARB is coming out. Breaking it down:  Probably 5 years since i inspected the bearings. Was super happy to find nice clean grease!  spindle seal is shot, on both sides  Difficult to see, but i cracked both upper kingpin bushings, so theyll need replaced  stripped bare, ready to start cleaning the housing:  parts!  As of today, the knuckles, wheel bearing hubs, spindles & caliper brackets are now cleaned & painted!  and i got my new collar for the ARB in the mail yesterday too  So now im putting together a shopping list of parts that i need to get it back together. I was looking at bronze kingpin bushings. Pricing seems to be all over the place, with RuffStuff @ $90, Branik @ $95, Ballistic @ $100, TMR @ $130, NWF @ $149, ECGS @ $159, etc etc. I cant see much of a difference in them, so not sure why the price is all over the place like that. This is the second set ive cracked, so i think while its apart im gonna upgrade to em. Probably going to run them in conjunction with the springless kingpin bushing kit from PartsMike. All my bearings & kingpins are in good shape, with the exception of the lower kingpin bearings. After cleaning theyre looking a little rough so im going to change them, and get new seals. upper kingpin seal, Spicer 620058 lower kingpin seal, Spicer 41777 for the spindle seal i was going to use the Spicer 708084 kit, which is the updated '2 seal' version for the 92-97 Ford axles, as im pretty sure this will fit the 79 D60. Comes with spindle bearing. Spicer 708084 The hub seal should be the same as pretty much every other D60 out there, National p/n NS 415960 From there i think im going to order a set of the 35 spline Yukon locking hubs for street use. The Spicers, while bomb proof, dont lock/unlock very easily, and im just tired of always disassembling them to get them to work again, so theyre getting replaced. I also need to spec and order a new pair of shocks for the front. So yeah, lots of parts to buy! Im gonna try to get everything ordered this weekend, and then next week yank the ARB out, change the orings, replace the collar and reinstall. If i get done before i get my parts in, then i guess ill move to the rear and start taking that apart (it needs wheel seals and rotors). Im hoping to drive this thing down the road before Xmas! So the next big part of the wiring job is the electric fan. I opted for a can controller from DC Control, specifically his model FK-75 controller. Its a PWM controller, rated for 75a continuous duty, and fully adjustable. For those that dont know what PWM is, its pulse width modulation. The short version is, it doesn't just turn the fan on, it pulses the power on & off, to control how fast the fan spins. This means you can run the fan at any speed you want, and it also means theres no big load on the electrical system when the fan starts. Most OEMs are now going this way for their electric fans, and its all over the industrial world as well since its so effective for motor control. Anyway.... So im running the windstar fan, which i installed on the radiator some time ago:  Its 2 single speed fans that Ford ran in parallel. Its not a high/low thing.  Fan controller:  Came with everything required to wire it up, so lets get to it!  Ok, first off, i want the fan to turn on when i turn the key on. I dont want to have to turn a switch on on the dash, because that also means i can forget, and overheat the engine. Youd think youd remember, but my old fan was wired that way, and i definitely forgot once or twice! This meant i needed a relay capable of handling 60+ amps continuous duty. Well, i found one, and its more affordable than you think Obtain Surplus: 75a relay  Conveniently, it fit right between my winch disconnect and the contactor. Perfectly. I didnt have to drill any holes, its the perfect spacing that its held in place by the screws from both of them:  fan controller mounted:  Fans wired. You can see the temp probe wiring poking out of the loom:  Temp probe. Its a delta temp probe that installs right in the radiator fins, and it is remarkably quick to respond to temperature change:  This was an interesting picture to take. I had to drill a small hole in the fan shroud for it to pass thru, and then wedge it into the fins. Then hold the fan away with one hand and try to snap a pic with the other!  Everything all done being wired & loomed:  So theres an input for A/C. When the A/C is on, it automatically turns the fans on at 50%. So i tied into the output for the pressure switch, this way it only spins up if the A/C is actually working. Which currently it isnt!  ...and there it is, the whole thing done!  So there was nothing left to do but test the system. And it works! So, if you were paying attention, you noticed an LED next to the switch for the winch control. Well, its for the electric fan:  This is a feedback sensor for the fan. When the controller first turns the fan on, it will blink red. Then, it will start off green. As the fan ramps up in speed, it will turn yellow and then eventually red once its 100%, so you always know how fast the fan is spinning. So, i ran the truck for almost an hour the other day to test it, and its amazing how well it works. First off, the PWM is amazing; even at idle the volt gauge doesnt even flinch when the fan turns on. The controller ramps the fan up to speed and then turns it back off since at idle, it cools it off very fast. Even with the engine held at 1100 RPM, the fan doesnt run full speed, which is quite promising. The controller is adjustable +/- 35º, so i can fine tune it if i need it to turn on sooner or later, but my preliminary testing seems to show that its gonna work just fine. So, this concludes the wiring portion of this project! Im taking the next week to get some projects done around the yard (and cleaning the garage). Then, the truck goes up on jack stands, and we will begin rebuilding the axles and suspension. We're getting ever closer to driving this thing! So this took a while, but the end result was well worth it. All the aux wiring is done!! So, i bought a relay box off amazon:  Switches are from OTRATTW. Locker, line lock, light bar & winch control switches installed:  i bought 18ga 12 conductor cable from Show Me Cables to wire the switches:   Wiring up the fuse/relay box:  I have one standalone circuit for each accessory, plus one spare already run from the box to the dash, so if i ever want to add another switch, all the wiring is already done. Everything is color coded; the switch wiring is color matched to the individual +12 for each accessory so i cant mix up any wires. There is also a key-hot power source turning on 2 of the relays; one is for the OBA system, and the second is for the elec fan, so i dont have to worry about remembering to turn either on.  ...and installed!  At this point, every accessory has been wired and tested for function. Made a trip to the junkyard last week to find parts for a buddies car, but i couldnt come home empty handed! 
I now have everything to do the power window/mirror/lock upgrade on the green bronco, except for a tan driver panel. One day ill find one. So ive had pretty good luck with the Badlands Wireless winch remotes. So i bought a second, and wired it into the bronco! Hidden here in front of the battery:  and some simple wiring to the contactor:  The power source is the switched output of my disconnect, that way the receiver only has power when the winch does. So from there i directed my attention to the dash. Removed the pocket from the dash panel, and made a switch panel (out of a cheap plastic tray from walmart) to take its place:   The finished product; i also added a hole for in-cab winch control, and that little LED is for my fan controller, altho we'll talk about that in another post  Laying out the wiring. I bought 12 conductor cable, so everything would be bundled together, and color coded: Youll note 3 extra wires. The brown is going to be supplied with a key hot, which will turn on certain accessories (such as the OBA & elec fan) as soon as i turn the key on. The 2 black wires are spares, just in case i decide to add an additional switch down the road; itll all already be wired up and ready to go, ill just have to stuff a switch in somewhere and tie in to those wires.  Going in for the final install:  ...and done!  I routed the harness thru the firewall where the cruise control used to enter, so no extra holes in the firewall. For now the cable is just laying across the engine bay, but the next step (starting tomorrow hopefully) will be to wire up the relay box for all this stuff! Ok, decided the next step actually was to re-install the OBA. This took longer than i thought, but atleast its done! So with the York on the passenger side down where the smog pump used to be, i had to completely rebuild my manifold. Started with the bracket to mount it:  after multiple tries, the rough draft:  the oil return for the york crank case is buried down there. I can barely see it, let alone get to it  So i bent up some 1/4" stainless tubing, to get it out and in the open:   Much better! manifold done and installed! That round black cylinder next to the alt is my intake filter.  3½ gallon tank underneath the rear bench seat:  air chuck at front bumper:  ...and the air chuck at the rear bumper:  I still have to re-run the air line for the ARB. Now that the solenoid is on the other side of the engine bay,the supply tube is no longer long enough, so i have to get some more. But aside from that (and the wiring), the OBA is done! So with that done, it looks like i cant put it off any longer, and next week ill be doing a ton of wiring. |
