00:00This is what 30mm spacers do to a 2021 Forerunner.
00:04Stock, the wheels sat tucked inside the fenders.
00:07Today we're fixing that.
00:08Full install, every torque spec, and the one measurement most people skip.
00:13If you can rotate your own tires, you can do this.
00:16Let's go!
00:17The truck, 2021 Forerunner, black, all-terrain tires.
00:21The spacers, 30mm Bonas forged, front and rear.
00:25Fitment specs, so you can check yours.
00:296x139.7 bolt pattern, 106.1mm center bore, M12x1.5 thread, hub-centric, 6061T6 forged aluminum.
00:40Tools, a jack and jack stands, cross wrench, a torque wrench, rust remover, a wire wheel, and shop towels.
00:48That's the whole list.
00:49Before the truck goes up, crack the lug nuts loose with the wheels still on the ground.
00:54Star pattern, just break them free, don't remove them yet.
00:57Jack it up at the frame, and set a jack stand.
01:00Never work under a truck held up by a jack alone.
01:03Ever.
01:04Now the nuts come off, star pattern again, and pull the wheel.
01:08Two hands.
01:09These all-terrains are heavy.
01:10Clean the hub, and this is the one people skip.
01:13Rust remover.
01:14Wire wheel.
01:15Then wipe it down until the surface is bright and flat.
01:18Any rust or gunk left behind keeps the spacer from seating perfectly flat, and a spacer that
01:25isn't flat is a spacer that vibrates.
01:27Set the spacer on.
01:28It should slide over the hub lip and sit dead flush.
01:32No rocking.
01:33No gap.
01:34That hub-centric lip is doing the centering, not the studs.
01:37On go the grade 10 nuts that come with the kit.
01:40Thread them all on by hand first.
01:42Never start one with an impact gun.
01:44Torque them to 113 newton meters, star pattern.
01:48We'll back on, and then install the factory lug nuts.
01:51Torque the factory lugs to star pattern again.
01:54Stands out.
01:55Drop it down slow, and here's the step everyone forgets.
01:59Torque the factory lugs one more time with the full weight on the ground.
02:02Then repeat everything on the other three corners.
02:05Same process, three more times.
02:08Loosen.
02:09Lift.
02:09Clean.
02:10Seat.
02:11Torque.
02:12Wheel.
02:12Torque.
02:13Drop.
02:14Retorque.
02:14And that's all four.
02:16Every spacer seated flush.
02:18Every nut torqued to spec.
02:19And here's the result.
02:21Same truck.
02:22Same wheels.
02:2330 millimeters wider each side.
02:25Flush with the fenders.
02:26You can see the spacer sitting right between the hub and the wheel, exactly where it should be.
02:31Quick note, we actually tested 25 millimeters on the front first, and 30 looked better.
02:37Full comparison video is linked in the description.
02:40Last thing, and it's not optional.
02:42Retorque everything after the first 50 to 100 miles.
02:46Aluminum and steel settle.
02:48Five minutes.
02:49Driveway done.
