Righty tighty, lefty loosey. It is a tough nut to get loode. Should not need to remove it for the rotors, but it has been a long time since I have done one.

Mazda 323/Protege front wheel bearing


The moment you can hear a loud noise coming from front wheels while driving straight that means that your wheel bearings are ready for replacement. In a Mazda 323 BJ (1999-2004) it usually comes every 150-200 thousand kilometers (95-120k miles). To replace the bearing (do two of them in one go even if only one can be heard) you need to do as follows:
Loosen the nut on the half shaft, jack up the car, remove the wheel, dismantle brake caliper and brake disc, remove all ball joints attached to the hub, detach the shock absorber from the hub (no need of removing it completely), once you have the hub basically hanging on the half shaft, untie the nut and pull the hub out of the shaft so you can hold it in your hands. You will need to go to a garage with a 12ton (minimum) press, no point of trying to hammer the bearing out as you may damage the hub and your whole work will be for nothing. Get the old bearing pressed out and the new one pressed in.The Mazda part numbers for the front bearing kit are: B455-33-047A(B,D),GJ21-33-042B,G304-33-065,B21M-33-048.
After getting the bearing fitted into the hub, all we need is to reverse the whole process, put the shaft into the hub, attached the hub to the shock absorber (makes it easier to attach the rest), put the nut and tight it just as much to feel there is nearly no movement (do not overtight it as this might damage the bearing), attach all ball joints back to the hub. Make sure all nuts are tight, use a
tension wrench when needed, put the brake disc back on the hub, install the brake caliper, once you have all them on and tight put on the wheel, then get someone to press the brake while you tight the shaft nut with the tension wrench, check the wheel for play or hard movement. Lower the car down and take a slow drive around (do not accelerate sharply or brake rapidly, just a gentle drive around. Normally a wheel bearing should be in correct position and use after about 200km (120 miles) distance. After that check if it is not overheating (too tight) or there is a play (too loose). Tight or untight if necessary, recheck after same 200km (120 miles).

I'm having the same exact problem as cpurdey with my 2004 Mazda MPV. My mechanic is quite certain it is not the wheel bearing or hub but seems to think it's a bearing in the transmission. Is...


If it gets worse as you're turning right, but not left - Most definitely a wheel bearing on the right side. The right turn puts more stress on the right wheel - louder noise - turn left and release the stress - no noise. You can also lift the vehicle up on a jack and listen to the wheel and hear the bearing in the hub making noise.

I know this sounds stupid, but did you remove the cotter key and the nut from the hubs flange on the outside? This is what keeps it linked to the axle splines the other bolts you removed keep the bearing /hub assembly tied to the front suspension. This answer is not meant to be insulting to you. Just a reminder. Some people do not know about the purpose of this nut at the end of the axle.

I want to remove the front break rotors from my '02 mazda mpv. I have the break callipers off, there is a large center nut on the hub. should this nut be removed to get the rotors off? or does the rotor...


Dont take the nut loose,the rotor should come off. If not it may be rusted to the hub. You may need to pry it off, I would not pound on it with a hammer unless you are going to replace the rotor anyhow.

How do I replace front rotors on a '03 Mazda mpv


MOST DO IT YOURSELF BOOKS EXPLAIN THE BRAKE PAD REMOVAL. WHEN THE CALIPER IS OFF THE ROTOR IS HELD ON BY TWO PHILLIPS SCREWS TO KEEP THINGS "TOGETHER" ON THE HUB. IT MAY ALSO BE TIGHT TO THE HUB, BUT IT WILL COME OFF.
ALWAYS REPLACE WITH NEW ROTORS SINCE MOST OF THE WORK IS DONE BY THE FRONT (DISK) BRAKES. SHOPS LIKE TO "TURN" OR RESURFACE ROTORS BECAUSE THEY HAVE THE MACHINE PAID FOR AND CAN CHARGE YOU THE PRICE OF NEW ROTORS AT A PARTS STORE FOR A LITTLE LABOR.

REPLACING FRONT HUB STUDS FOR A 98 HONDA PRELUDE


To remove that hub you will destroy the bearing. Because you have to remove it with a slide hammer. It is not necessary to remove the hub to change the studs. Remove the caliper, caliper bridge and rotor. Using a hammer simply knock out the stud or studs you want to replace. Put new stud in and using a sleeve that has a bigger diameter than the stud (I use a big nut, like the one on the axle) put big nut over stud and screw lug nut on stud and tighten until head of stud is flush with hub. Re-install rotor, caliper bridge and caliper. Hope this helps.
