Clutch, transmission, rear axle.
Post Reply. I want to convert at least the rear end to either a posi-trac system or to have lockers. I am on a limited budget and would like to be able to install myself. This truck is a tank in 2 wheel drive and my 4 wheel drive will be working for the 1st time since i have owned the truck starting at the end of December, but i still want the ability of lockers or etc.
What would you 4x4 guys recommend? I have a newly rebuilt auto c6, hi and low 4x4 ranges, and plenty of power with my rebuilt so power and gearing are not a problem, but i want to be able to rock crawl a little and not worry about the easiest tire only spinning in the mud.
For the right price i would do a front and rear system. Thank you, Ryan. Re: Converting rear dana 60 to either posi track or What? Quote Post by averagef » Thu Dec 08, pm If the truck has the original 16 spline 60 rear you don't have many options.
AFAIK you've got spline detroits, powerlocks and track-loks in 16 spline. Track loks suck and the old detroits are pretty rough, but they do work great if locked is what you want. The original kingpins needed to be removed since I ordered the full rebuild kit and it comes with new ones. One side popped loose fairly easy while the other side needed some persuasion with the torch.
We used two well matured Live Oak trees to hold the housing while we performed this operation. I stood on top of the axle to keep it from flipping over while my father did the real "work". To show you how tight the one kingpin was, we almost rounded off one of the hex adapters before switching to a back up. I'm glad East Coast Gear Supply threw in another unit with my purchase Here the front housing was sandblasted much like the rear.
We also coated the inside of the housing with black Rustoleum enamel. Unfortunately the previous owner wheeled the truck so hard that at some point the axle slid back and was taking a beating by the centering pins in the leaf pack. The passenger side was all smashed while the driver side was wallowed out in the cast perch.
The MIG welder and more grinding solved this issue. With the axle mods now buttoned up, the same trees were used to torque in the new king pins. The service book says ft. To achieve the pound rating, the torque wrench only needed to be set at 96 ft.
We also coated the insides of the axle tubes with Rustoleum primer to prevent any further scale rust from forming. After 3 weeks of not working on the truck, almost all parts finally showed up.
The bench has never been this cluttered! Boxes of bearings, seals, gaskets, bushings and other aftermarket parts make getting tools off the wall difficult. Again, Superior 4. These are not the thick gears rather I am using the regular offset since I scored a 4. Also shown on the bench are my new dual piston calipers. I chose to use the one piece design instead of the two piece design of the 70's. I doubt they are any stronger but they were less expensive and they had a cheaper core charge!
These units pictured did not fit the ''91 axle as those calipers have a different shaped slide rail lock. My calipers actually came from the 's E van applications. Since they are Ford calipers not Bendix or Dayton my best guess is Ford tried to make as many parts universal as possible.
The inner tubes were painted Rustoleum black so hopefully no further rusting will prevail. Now the fun stuff starts to happen. Again we find ourselves performing our own gear setup and amazingly this time it only took us one try at a "perfect" pattern. I could not believe all the difference 0. The backlash checked in at 0.
The case spreader worked like a charm to keep from fighting the carrier in and out of the hosing. The up Superduty front axles D50 and D60 came equipped with a neat cartridge tube seal design.
This design has the outer seal riding on an inner seal portion instead of the axle shaft directly. So here is how we made it work: we simply ground down the outer metal ring until it fit snug inside the tube. Once the axle shaft is inserted, the inner seal is allowed to "float" within the outer seal. The bottom left two pics show the inner seal furthest outward and then furthest inward. Also shown is our handy seal install tool.
Finally, here are the beauties that have been in storage since the first days of the build. They really are works of art as compared to the original castings. However I do not much care for the bright orange color scheme. This will be changing very shortly! I really do not understand why people go through all of the headache to plate their original knuckles.
