Slide off - after removing mounting bolts
No. Brake rotors don't have bearings, the wheel hub does.
No. The bearings are not that type.No. The bearings are not that type.
In the brake rotors.
It's posible, but not hugely likely.
If the noise only happens during braking, a rotor probably has a very poor surface finish and needs to be resurfaced so as not to rapidly wear the brake pads. If the rotors are drilled or slotted, the noise is perfectly normal and can be ignored. If the noise occurs while driving along and gets louder at higher speed iit may be due to damaged wheel bearings. On some vehicles, removing a brake rotor requires removing serviceable wheel bearings. It is necessary to repack the bearings with grease and adjust the freeplay in the bearings when reassembling. Incorrect freeplay or and dirt or grit introduced into the bearings can cause this problem. With slip-on "hat type" brake rotors, they can sometimes be fused to the wheel hub by rust. Often-times a mechanic will remove the rotor by beating it into submission with a sledge hammer. This can damage sealed bearing units.
The 1996 Pontiac Grand Am is a front wheel drive application. This vehicle has sealed (non-serviceable) and bolt-in wheel/hub bearing units. Removing and replacing them involves removing the wheels/tires, brake rotors and then unbolting the wheel/hub bearings. The General Motors OE front hubs are AC Delco #2025K.
Tap on the rotors with a hammer, after removing the tire and wheel and the brake assembly. The rotors will come loose. Slide the rotors off and reverse the process.
You can't, only tapered roller bearings as used in drums & rotors on some vehicles are adjustable. The rest are just sealed bearings and/or hub & bearing assemblies that are sealed
Bad bearings inside or loose castle nut.
Good idea to do so
Hermetic motors are motors used in hermetic compressors. Hermetic motor use wound stators and squirrel cage rotors, without shaft bearings and have a relatively tight design.
