Re: front rotor nut
Hi out of curiosity? are wanting to renew thebrake disc/rotor ? or the actual hub that rotor fits to ? as not usually necessary to have to remove hub to change rotor ? unless the rotor is bolted to hub from the rear ?

TO REMOVE FRONT WHEEL BEARING.YOU NEED TO SAFELY RAISE SUPPORT VECHICLE ON JACK STANDS.MAKE SURE SITTING ON LEVEL SOLID GROUND.BEFORE RAISING VECHICLE OFF GROUND YOU NEED TO LOOSEN HALF SHAFT AXLE NUT JUST A LITTLE BECAUSE WHEEL IN THE AIR HARD TO LOOSEN AXLE NUT WHEN YOU HAVE HOLD THE WHEEL WHILE LOOSEN THE AXLE NUT WHICH IS TORQUE ON ABOUT 200 FT LBS.USING A SIX POINT AXLE SOCKET SOCKET SIZE COULD BE 34 OR 35 METRIC 1/2 INCH SOCKET.YOU NEED 1/2 INCH BREAKER BAR.ONCE YOU LOOSEN AXLE NUT A LITTLE THEN RAISE VECHICLE THEN REMOVE WHEEL.THEN FINISHING REMOVING AXLE NUT AND WASHER.THEN REMOVE THE CALIPER FROM THE STEERING KNUCKLE AND SUPPORT IT ASIDE USING A PIECE OF WIRE.REMOVE BRAKE ROTOR.THEN REMOVE THE 3 HUB BEARING ASSEMBLY BOLTS. USE A SWIVEL SOCKET GOING TO BE HARD TO REACH SPOT WITH A REGULAR SOCKET. REMOVE THE HALF SHAFT FROM THE HUB BEARING ASSEMBLY.REMOVE HUB AND BEARING ASSEMBLY. PUT EVERY THING BACK VISA VERSA. TORQUE HUB BEARING BOLTS TO 70 FT LBS. TORQUE AXLE NUT 284 FT LBS IF YOUR CAR IS 1998 MODEL AND TORQUE AXLE NUT 100 FT LBS FOR THE 1999 TO 2001 MODELS.THE WHEEL HAS TO BE ON THE GROUND JUST ENOUGH TO KEEP IT FROM TURNING.DONT LET ALL THE CAR WEIGHT DOWN UNTIL YOU HAVE TORQUE WHEEL TO THE RIGHT TORQUE.LET ME KNOW IF YOU HAVE ANY PROBLEMS.
-Jack up the car -remove the tire, 19mm socket -remove the brake caliper, its either an 18mm or 15mm socket that will remove the bracket bolts. -remove the rotor -remove the axle nut, its either a 34 or 36 mm -unplug ABS sensor connector if equipped -remove the three bolts that hold the bearing/hub assembly to the knuckle, a 13mm socket will work Remove the wheel bearing.
It is important to tighten the axle nut to the proper spec. Failure to do so will cause the new bearing to fail. you will need a 1/2" torque wrench for this.
To make removing and installing the axle nut easier place a punch in the fins of the rotor and rotate the rotor until the punch rests on the caliper (it doesn't hurt to put a couple lug nuts on to hold the caliper tight to the hub). This will hold the hub in place while you looses and tighten the axle nut.
There are some special 4 tooth and hex sockets for removing the nuts inside the hubs of the truck. YOu can find these at NAPA or maybe AutoZone or Advance. I would go to NAPA because they more than likely have it and also know something about repairing this assembly. Ford uses Dana front end parts and NAPA has original Dana parts in stock... so it is as good as or better than original and they would have the tool for it. Be careful and follow the procedure exactly for putting the front hubs back together. YOU CAN RUIN THE FRONT END OF THE TRUCK IF YOU DO NOT PERFORM THIS SERVICE CORRECTLY. And trust me... many of the idiots working in repair garages do not know how to do these older 4x4 hubs either... ask someone and read the books for the right procedure... some of the older mechanics may show you how to do it. Ask
Well it is a little bit of a process. 1 take the tire off. 2 remove the caliper and the caliper bracket. 3 remove the rotor, this should just slide off after the caliper and caliper bracket are off. 4 using an alan wrench remove the hub locking cap. 5. remove the spanner nuts, it would be a lot easier if you by a spanner nut socket, however it can be achieved using a screw driver and a hammer. just do hit it to hard. 6. pull off the hub. be careful because the internal bearing will come out. keep them off the ground. 7 now you should be down to the spindle, there should be 5-6 nuts holding the the spindle and dust shield on to the axle. I would also get a Haynes manual at the local auto store. I hope this helps please rate this Thank You
I'm not positive what type axle you have but the order of parts should be the anti lock free running hub assembly, a lock washer then the wheel bearing lock nut. The lock nut could look like a thick washer with 5 or 6 holes in it. But depending on your front axle you may have a rotor and hub assembly that's a single unit or they could be separate. If they are separate then you may need a sledge hammer to get the rotors off. Ford's front rotors can be a real pain in the a$$ to get loose. Regardless which type you have if the order of what you have taken off so far matches what I said then washer is probably the locking nut. The only way to get it off is a special spanner wrench or a punch and hammer. If you are still uncertain about it let me know and give the axle make and type and I'll be glad to help. Good luck If
IF its a 1990 Ford f-150 its easier than looking at pictures,pictures in black and white are sometimes hard to understand, here is some steps to do it: pull off brake caliper then pull off 4x4 locking hub or the 6 allen head bolts,then there is a large o ring that holds in the aluminum hub,pull that off,then there is a smaller snap ring around the axle shaft,pull that off then the whole 4x4 locking hub unit comes right out.then you need an axel nut socket which is about $15.00 at the auto parts store to pull off the large nut that holds the hub on,that socket has to be for that year and if its heavy or light duty,pull off the rotor and hub together,then there is about 6 bolts that holds the hub shaft to the spindle,unbolt them and work the hub back and forth till it comes out.you can use a piece of wood against it and hit it with a hammer but dont hit the threads on the hub or you wont be able to reassemble the rotor and hub tight.then the axle just pulls straight out with a little wiggling.For reassemble reverse this order and it should go pretty well.Both right and left comes out the same way,but on the right there is a rubber boot with a clamp where the axle seperates towards the center of vehicle.
YOU will need to remove fornt hub/rotor assembly. this will reveal the spindle and 5 nuts holding it to the knuckle remove nuts slide off spindle and axle will then come out. then you can replace joint
