[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]So much to catch up on................
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]When we left off I had finished the paint on the front frame rails and we are ready for final install of the front suspension, also the transfer case was ready to go in
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]Well the t case is in, I will get some pictures of that
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]Meanwhile I have been finishing the suspension install and have made LOTS of progress
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]Let's start with some pics!!
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]My notes from the last time I installed a 31 spline 8.8 into a lifted ranger (the 300K jasper 306 truck [font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]v8 build here[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif])
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]That is all we need to mock up and start welding!!
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]RuffStuff kit, some nice stuff!
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]U bolts are too short, its all right I can use them on an Explorer
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]the new spring perches come with tabs on them, these would fit a 3" axle tube nicely
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]Well our 31 spline 8.8 has 3.25" axle tubes, so off with the TWO END tabs, leave the middle for nice weld spacing
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]much better
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]Now to center the axle under the truck, and measure the pinion angle
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]I measure in from each backing plate and check my marks a couple of times
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]mock up rear axle loosely with new perches, stock blocks, new U bolts (12.5" long), and spring plates.
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]Once she is close to center I make sure the perches are in EXACTLY the same spot on the axle, distance from backing plates. I also check to ensure they are 38.5" apart center to center, This ensures our axle is centered and our leaf springs are straight
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]Perfect.
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]Now to set the pinion angle
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]Stock Ranger pinion angle is 7 degrees
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]I know from the last umpteen V8 4406 Rangers I have built that with a 2 u joint rear driveshaft (4406 slip yoke) we want to match the new pinion angle to the tail housing angle on the transfer case. Which is 7 degrees...
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]Now the Chevy leaf spring setup with the inverted rear shackle is a bit different from other rangers but I am still able to easily set my pinion angle at 7 degrees by measuring 0 degrees at the old explorer spring perches. I always leave the old explorer spring under perches on these axles because:
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]They have the bolts that retain our brake lines in place
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]They make an excellent spot for your floor jack
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]This truck MIGHT go spring under someday down the road
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]The ranger U bolts will clear every time, the explorer and ranger leaf spring center line distance is within 1/2"
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]Transfer case was installed
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]Tailhousing angle was checked
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]Pinion angle adjusted to exactly 7 degrees
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]Spring perches can now be tack welded to axle tubes
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]
[font="Segoe UI", "Helvetica Neue", Helvetica, Roboto, Oxygen, Ubuntu, Cantarell, "Fira Sans", "Droid Sans", sans-serif]Time to mock up the new shock mounts
