Truetrac (911A644) for the front 7.5" clam of Jordan's 2000 4Runner
(16 BIG pics loading)
NOV 24 2017

Jordan's 2000 4Runner 3.4L traveling in Wyoming.

Rumor has it that some of the Truetracs in the 7.5" and 8" and 9" clams do not properly secure the driver's side axle stub shaft
and the shaft walks out a little and leaks gear oil past the seal.

This particular Truetrac 911A644 was measured and checked out by the pros at ECGS and determined ok and fowarded to me for this install.
It's not obvious, probably because it was done so neatly, but the bushings inside the journals are the special ECGS PTFE bronze inlaid bushings.

Easiest way to get the passenger side stub shaft out is to take a long 3/16" pin punch and punch it from the opposite side.....

...and out the stub falls.

Now remove the 10 bolts............

....and the lid is now free.

Switch the original 410 ring gear over to the Truetrac and reuse the carrier bearings if they are in very good shape like I did here.
The carrier bearing preload and the backlash are controlled by the washer plate selection. Those had to be changed out
3 times as indicated in my final assembly notes. FIPG is then applied to the lid....

....and 51 ft/lb on all 10 bolts.

Every 3rd tooth is checked for backlash value.

A new Driver's side seal (90311-47027) is then tapped flush

Here are the final assembly notes. The pinion end remained undisturbed. Before, there was no carrier bearing preload
and now there is a respectable 6 in/lb worth.

The magnetic drain plug is shown with the stub and the clam.

The shell casing cleaned up very nicely.
