Step 1: Loosen the lug nuts a little then jack the car up and place it on the jack stands.

Step 2: Finish removing the lug nuts and remove you wheel and tire.

Step 3: Remove the 2 bolts that are holding the brake caliper, you will need a 17mm socket.

Step 4: A hose attached to the caliper is in your way. I zip tied the caliper to keep it out of the way and keep the hose intake.

Step 7: Remove the old spindle nut. You need to replace this part, it cost me $3 from my local Acura dealer. You may need to use your torque wrench. You get more control that way. The nut requires a 32mm or 1-1/4 socket. I have included a picture of the old one vs. the new one I got from the dealer.

Step 8: Use the hub puller (slide hammer to remove the hub). I rented the puller from AutoZone. It cost me $86 to rent the tool, but when I return it they give you all money back. The puller has 3 claws that hold the hub, you slide the hammer back and use that force to remove the hub. It may take you a like 30 pulls. Don’t rush it, stay as horizontal as you can. You will avoid damaging your wheel bearing if you do it right and have some patience. After removal inspect your wheel bearing. If damaged you should replace it. AutoZone sells them new for around $47.

Step 9: Here is what the hub looks like after you remove it.

Step 10: Use your sledge-hammer and the piece of wood to hammer out the broken stud. I choose to remove all the old studs and replace them with all new ones. With all the work you are doing you might as well replace them all. I bought my wheel studs from AutoZone for $2 each.

Step 11: Now you need to get your new studs on the hub. They are a little harder to put on then to hammer out. If you have a vise use it to hold your hub and hammer in the new studs, you can also use an impact hammer, or take it to a shop to be pressed it. I took my hub and 4 new studs to my local Les Schwab and they pressed them on for me for free. Here is what it looks like.

Step 12: use high-temp wheel bearing grease and lube up your hub. It’s going to need a new coat, it will also help with the re-install of your hub. Hammer in your hub back onto the knuckle of the car. I didn’t replace my wheel bearing because I didn’t damage mine. Either way be careful when re-installing the hub as not to damage your new or current wheel bearing.

Step 13: When you have enough tread on the driveshaft showing, start screwing in your new spindle nut. If it slips off you need to hammer in your hub some more. Take your time, you may strip your new nut or even the drive shaft tread if you are careless.

Step 14: When you have on the nut going a little starting using your 32mm or 1-1/4 socket and torque wrench and tighten up the nut. You will need to set your wrench to 134 ft lbs of torque. Once you hear the click stop. Use your hammer and a large flat head screw driver to make a dent from your spindle nut into a wedge that is on the driveshaft end. This prevents the nut from coming off.
