The stud cover is the hub and you cant get it out because its pressed into the wheel bearing that it attached to the spindle,you can rent a slide hammer that bolts up to the hub and slam away,but you have to have it pressed back in. so remove the spindle mark strut holddown bolts so your alingment isnt too far off.hope this helps let me know if you need more info or diagrams have a good day DB

How to change CV joint mazda 323 mod 1991


In order to change the cv joint, you will need to remove the wheel and the brake caliper and rotor. Raise vehicle on jack stands. Remove the wheel and remove the brake pads and caliper. Tie the caliper up out of the way, do not disconnect the brake line attached. Once the caliper is removed, slide the rotor off. Using the correct size socket, remove the nut in center of hub. Some vehicles have a kotter pin in the shaft just in front of nut. If so, remove pin before nut. Next, you will need to loosen a few bolts that hold the strut to the hub assembly. Once you have hub free from strut, turn the hub either left or right while having someone push in on the cv joint while turning joint left or right. Doing so will allow the joint to slide out of hub. Next, using a pry bar, insert between end of transaxle and transmission and pry out. To install new axle, align the axle with transmission and slide into transmission. Carefully work the other end of axle into the center of the hub assembly. Once you have it in the hub, tap gently with a rubber mallet until you hear it "pop" into transmission. Once it is in transmission, replace the bolts connecting the hub to strut. Replace nut on center or cv joint and tighten just until it seats against the hub...do not overtighten. Replace kotter pin with new pin. Slide the rotor over the studs, replace caliper and brake pads, install wheel and you are done.

2004 ford explorer tire bushing on front tires, when taken off cant see where to lube them? does anyone know??? Leave me a comment at prbonz71@aol.com


There are no "tire bushings". There is a complete front wheel bearing assembly that if bad, will need to be replaced. There are also no lube fittings on any of these assembly's. You need to remove the entire brake assembly, rotors, calipers, and caliper mount just to get to the nut for the front wheel bearing. Then you have to take cotter pin out of the main nut on the end of the axle, and take off the nut locking nut, you will need a 32mm socket, (if memory serves me correctly) to take the axle nut off. Then there will be 3 bolts on the back side of the axle housing that will need to come out, unplug your electronic brake wire, and the wheel bearing should fall right out.

2007 Dodge Magnum, RT/AWD - Front Driver side wheel area noise, like snow/ice was caught up under, checked notheing. One month later the noise came back but with a vengence. Now makes the noise at all...


Check the Brakes first. Are the pads worn down to metal. Is the Caliper Stuck (open)?
Raise and Support the Front and Rear (because of AWD) of the vehicle.
Remove the left front tire. Make sure the Parking Brake is engaged. Place the lug nuts back on the lug studs. Place the Vehicle in Neutral. Turn the wheel (without the tire on) and listen for where the noise is coming from. A bad bearing will feel rough (not smooth) and sound 'crackly' when trying to turn the one wheel. Make sure it is not from the CVJ.
If not smooth: Remove and Replace the wheel bearing. And yes you can do it yourself saving you about $150-$200 dollars. It is a bolt-on (4 bolts) bearing. Bolt Heads should be on the back side of the steering knuckle.
Remove the Brake Caliper, Caliper Brace, and Rotor.
Remove the 4-bolts (turn the wheels left and right to better access these bolt heads) and slip the bearing off the Axle. You may have to hit the bearing to loosen it.
