How to Install a New Hub Conversion Kit
Installing a new hub conversion kit is quite tricky. If this is your first DIY-project, then we highly recommend having an experienced DIY-er or local mechanic assist you during this installation process. To help you cut down on installation time (and effort!), we're also offering you a step-by-step guide on hub conversion kit installation.
Difficulty Level: Difficult
Tools that you'll need:
- Hex key/Allen wrench and sockets
- Emery cloth or die grinder (with flap wheel)
- Common hand/air tools
- Jack and jack stands
*For the size of the Allen key and socket/s, refer to the product manual or your owner's manual. Also, be sure to park on level ground.
Step 1: Inspect all the parts included in your hub conversion kit. Make sure nothing's missing.
Step 2: Raise the vehicle and support it using your jack and jack stands. If necessary, block your rear tires to prevent the vehicle from moving.
Step 3: Carefully remove your front wheels. At this point, you should see your calipers. Take these calipers and remove them, but do not remove your brake hose. If your vehicle comes with an ABS sensor, remove the ABS sensor along with your rotor.
Step 4: Locate your factory unit bearing and remove its bolts. Pull out your OEM bearing. Your axle shaft is connected to this bearing, so the shaft should come out with the bearing.
Step 5: At the end of the axle shaft, you'll see a retaining nut and a cotter pin. Remove these small components.
Step 6: Disengage the unit bearing from your vehicle's stub axle, then pull out the stub axle from its inner axle.
Step 7: Install your new stub axles along with its accompanying seals, spacers, and dust shields. Check each component's connections and make sure they're airtight.
Step 8: Check your kit's races and wheel hubs. If the new hubs don't contain its wheel bearing races, install the races into the hubs. Make sure the wheel bearings are packed with grease, and then attach your wheel seal to the back of the hub.
Step 9: Your wheel hub should contain your rotor. If it doesn't, install your rotor.
Step 10: Locate your steering knuckle and make sure it's clean. This is where you'll be attaching your new spindle. In some cases, a die grander with a flap wheel is necessary in removing rust on the steering knuckle and its hole.
Step 11: If you're planning on installing a new inner axle kit, you can install this kit at this point. Otherwise, proceed to applying grease on the inner axle shaft splines and on their actual seal area.
Step 12: Slide the axles back into the housing.
Step 13: Lubricate the seals and outer axles using grease. Also put anti-seize on the spindle hole and its mating surfaces.
Step 14: Install your dust shield, then your spindle. Tighten its bolts according to the torque indicated on the product manual or your vehicle owner's manual. If your vehicle has an ABS sensor, you have to install it. Otherwise, proceed to the next step.
Step 15: Install the hub rotor assembly or hub. Make sure the assembly is correctly attached to the spindle. During this process, avoid damaging its seal. When properly installed, the bearings should slide in place on the spindle. If this doesn't happen, try reinstalling the hub.
Step 16:Install the locker washer and the outer locknut.
Step 17: Check the torque on the rotor and front disc brake hub. This should not go beyond 2.3 nanometers (nm). Also make sure the front wheel spindle's final end play is at 0.00-0.11 millimeters (mm) only.
Step 18: If applicable, install your hub locks.
Step 19: Reinstall your caliper and wheels. Make sure all the lug nuts are tightened to reflect the correct torque. Triple-check all your bolts and nuts to ensure that there are no loose connections.
Reminder: Be sure to recheck all connections (bolts and nuts) after 50 miles, and again, after 500 miles.
