Yukon Gear Master Overhaul Kit for 2016+ Toyota Tacoma 8in. Automatic w/o E-Locker
A third-generation Tacoma that has started to hum from the back at 45 to 65 mph, whine on coast-down, or weep gear oil around the pinion yoke usually needs its rear center section rebuilt, not just a fluid change. The Yukon YK TV6-C is the master overhaul kit Yukon builds for one specific axle: the 8-inch rear in 2016-2023 Tacomas with an automatic transmission and no factory rear E-Locker, in both 2WD and 4WD trucks.
The open-carrier Tacoma rear is a Toyota 8-inch (Yukon groups it as the TV6, the V6-style rear with the larger 29-spline pinion). The pinion turns on two tapered roller bearings, and the carrier and ring gear spin on two side bearings. Yukon's fitment notes call out a 53mm carrier bearing ID for this axle, which is one reason a kit for an older Tacoma or 4Runner rear will not drop in. When those bearings wear, the pinion and ring gear stop meshing at the right depth and the gear set starts to sing. A master kit replaces the wear parts in one go so the gear contact can be set from scratch, which is the only way the noise goes away for good and the ring and pinion survive.
Rule out tires, wheel bearings and the transfer case first. Our Toyota 8-inch differential problems guide walks through the Tacoma rear specifically, and the whine on acceleration vs deceleration guide helps you tell pinion bearing wear from ring gear contact. With the rear on stands, grab the yoke and rock it: any up-and-down play means the pinion bearings are done. Drain the oil and look at what comes out before you order parts.
Yukon lists the YK TV6-C for 2016 through 2023 Toyota Tacoma, 2WD and 4WD, automatic transmission, 8-inch rear, without the factory electric locker. That last condition matters most. Trucks built with the rear E-Locker (TRD Off-Road and similar packages) use a different, larger rear and need the Yukon E-Locker Tacoma and 4Runner master kit instead. Earlier 2002-and-older V6 and Turbo 4 rears take the YK TV6 kit. If your truck has a manual transmission, or you are not sure whether it has the locker (look for a rear diff lock switch and the actuator on the housing), send us the year and VIN before ordering.
Pullers and drivers make the bearing swap far easier; our hydraulic puller and bearing separator set handles the carrier and pinion bearings.

No. Yukon lists this kit only for trucks without the factory rear E-Locker. Locker trucks use a different rear and need the Yukon Tacoma and 4Runner E-Locker master kit.
Yes. Yukon's fitment covers 2016-2023 Tacoma 2WD and 4WD with the automatic transmission and the 8-inch rear without a locker. Manual-transmission trucks should send us the VIN before ordering.
Yes, if the teeth are not chipped, pitted or blued. The kit replaces the bearings and seals, and you reset pinion depth, preload and backlash to the original gears. If you are going to bigger tires, regear at the same time since the labor is the same.
Revolution Gear's chart lists 12-15 in-lb pinion preload on new bearings, .006-.010 in. backlash, and 70 ft-lb for the ring gear bolts and bearing caps. Always check against the instructions in your kit and the factory manual.
Use the GL-5 hypoid gear oil and viscosity listed in your Tacoma owner's manual for the rear axle. Change it again after the first few hundred miles of break-in to flush out wear material from the new parts.
If you have a bearing puller, a press or drivers, an inch-pound torque wrench and a dial indicator, yes. Setting pinion depth and backlash takes patience. Without those tools, most owners buy the kit and have a driveline shop do the setup.
