Jason's 2015 Tundra with 5.7L motor.
He has the AB60F auto tranny with a nice, deep .58 6th gear overdrive. |
|---|
|
|
Looking up the VIN number....not only is it a 5.7L it's 32 valve...4 valves per cylinder....
Double overhead cam and will accept "flex fuel" (corn gas). |

Parts obtained from JustDifferentials.com
10.5" master bearing kit...Auburn LSD...Nitro 529
and 108 pounds of stock 4.30 3rd(4.30 comes with the towing package). |

|
|
| 529 gears represent a 23% gearing improvement over the 430 factory gears. |
|---|
|
|
| With a 22mm socket, remove the 12 massive ring gear bolts. |
|---|
|
|
| Pressing the new 529 ring on. It was a very tight fit. |
|---|
|
|
| Red Loctite and 145 ft/lbs. |
|---|
|
|
| Now, onto the pinion end of things....pressing the pinion out. |
|---|
|
|
| I stock these genuine factory 10.5" pinion seals. |
|---|
|
|
| The hi-tech pinion seal removal tool. |
|---|
|
|
| Pressing the smaller outer pinion race out without disturbing the oil retainer. |
|---|
|
|
| Thank you Scott for the kool yet simple idea for this "tool". Old outer race is out. |
|---|
|
|
| Totally undisturbed oil retainer. |
|---|
|
|
| Let's try .0473" as the first pinion shim depth. |
|---|
|
|
| Pressing the bearing on with the Harborfreight press. |
|---|
|
|
| New outer pinion race is going on now. |
|---|
|
|
| tap tap tap |
|---|
|
|
| Old bearing parts....they become tools of the trade. |
|---|
|
|
The larger inner race takes more finesse to get it to pound down all the way.
Got to start it straight and level. |
|---|
|
|
| The 99 cent bubble keeps it level. |
|---|
|
|
| Once it is started straight, it will go down pretty easy after that. |
|---|
|
|
| Bingo ....it's down 100% of the way. |
|---|
|
|
| Now to load up the pinion...tighten up the nut just enough to get about 10 or 15 inch/pounds of pinion bearing preload. |
|---|
|
|
| Now is a good time to tap on the carrier bearings....they went on very very tight. |
|---|
|
|
It's good to have a large selection of factory washer plates for the carrier bearings.
You know, for such a big heavy duty 10.5" diff, these washer plates are fairly cheap ass quality.
Just my observation. |
|---|
|
|
| Bang bang bang with the brass hammer. |
|---|
|
|
| Keep adjusting the washer plate thickness until the backlash and preload are in the zone. |
|---|
|
|
| The red bar is a SkyJacker draglink for a 1999 TJ Jeep. It's been put to good use.. |
|---|
|
|
| Drive side.....too deep. |
|---|
|
|
| Coast....deep. |
|---|
|
|
| The comet tail....definitely says "too deep" based on how heavy the contact is on the outside edge. |
|---|
|
|
| Ditto. |
|---|
|
|
| Gear installs tend to have alot of repetition....so push the pinion out again to adjust the pinion shim thickness. |
|---|
|
|
| Let's reduce the shim thickness by .0063" (for a final .041"). |
|---|
|
|
| Some more tweaking of the washer plates now. |
|---|
|
|
| Driveside....ohhhh ya, beautiful! |
|---|
|
|
| Coast is good. |
|---|
|
|
| The comet tail should be near the center and possibly halfway closer to the root. |
|---|
|
|
| And this comet tail is in the sweet zone. |
|---|
|
|
| Satisfied with the pinion depth, now the pinion can be pressed out and the solid collar installed. |
|---|
|
|
Pretty cool that the factory uses a solid collar in all their 10.5" diffs.
Having a complete solid collar shim selection is critical here.

| With backlash and carrier bearing preload dialed in, now the 4 bearing cap bolts can be verified to be at 151 ft/lb. |

A shot of the washer plates. Not a complete selection YET....but $300 worth of them are on their way to my shop right now
.....and they will soon be a complete selection. |
