|Truetrac (911A644) for the front 7.5" clam of Jordan's 1999 4Runner|

|NOV 24 2017|
|Jordan's 1999 4Runner 2.7L 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.|
|And now it's heading to California. :)|
