You first have to separate the motor from the pump chamber. Remove the impeller carefully, it usually unscrews opposite direction of rotation. (Be careful with the ceramic seal inside pump chamber, it's delicate. ) When the motor is separate, unscrew the end with contacts and carefully pull this aside.
-Whenever I do this job, I always replace BOTH bearings. For a bearing cost usually less than $15 it doesn't make sense to commit all this labour to change only the faulty bearing. (the other may go in a month or two then you repeat all the labour ) Pull both bearings and carefully insert both NEW bearings. Re-assemble everything in opposite order. Fit new gasket on pump chamber. Screw pump chamber together doing opposing screws after each other (imagine 6 screws in a circle, loosely do all 6 then tighten 1 then 3, then 5, then 2, then 4 etc. This way the gasket will be even as opposed to tight on one side (if it's a Jet-pump this is VERY important ! )
With Bush and bearing replacement.
Pump surging - if a pump doesn't have a minimum flow it will build up discharge pressure. When this discharge pressure gets high enough the pump cannot overcome it any more and the water starts to flow backwards. When the water starts to flow backwards, the pump slows down. The impeller will start to spin backwards building up pressure again. The water inside the pump will shift back and forth wreaking havoc with your pump impeller. This cycle of spinning forwards and backwards will repeat itself and will destroy your thrust bearing and destroy your pump. This can happen with any type of centrifugal pump, if you block the discharge the pump will build up pressure and surging can take place.
the impeller of the pump, discharges the water of a steam or air or electric driven pumps.
This varies from pump to pump because centrifugal pumps can be designed for various applications. The maximum height a pump can pump water depends on size of pipe/water column, friction, power available etc. This is often reffered to as the head of the pump. A water company would probably have some centrifugal pumps capable pumping to over 300m in a 30 inch main.

The bearing is on its way out. Replace the pump soon.
if the bearing is noisy or the pump is leaking replace the pump.It is a job to replace but if you wanat to get a manual on your car from DISCOUNTAUTOREPAIRMANUALS.COM
You need to replace the water pump. It is likely the pulley came off because the water pump bearing failed and siezed.
The most obvious would be coolant leaking from the weep hole. A noisy and or loose water pump bearing would also be a good reason to replace the pump.
1 A seal protects the water pump impeller shaft bearing from contamination by engine coolant. If this seal fails, a weep hole in the water pump will leak coolant. If the weep hole is leaking, shaft bearing will follow. Replace the water pump immediately. 2 The water pump impeller shaft bearing can prematurely wear because its mechanically driven. When the bearing is worn it will squeal and it needs replaced don't confuse it with belt sequel though.
There are 3 diffrent ways to tell if you got any of these signs replace water pump # A seal protects the water pump impeller shaft bearing from contamination by engine coolant.If this seal fails,a weep hole in the water pump snout will leak coolant. # The water pump impeller shaft bearing can also prematurely wear out.When the bearing wears out,it emits a high-pitched squealing sound. # To identify excessive bearing wear,grasp the water pump pulley and try to force it up-and-down or from side-to-side.If the pulley can be moved the bearing is nearing the end of its service life
Make sure the seal between water pump and engine is not leaking. The seal protects the the bearing on the water pump impeller shaft from contamination's from the coolant. IF water is leaking out of the weep hole on the water pump snout, A small amount of gray discoloration is normal, a wet area with brown discoloration means the seal has failed. Replace pump immediately. The water pump impeller shaft bearing may prematurely wear out, if the pump is noisey during normal engine operation, the bearing has failed. Replace pump immediately ( no not get confused with belt noise, loose or glazed belts will emit a high pitched squealing noise.). To see excessive wear in bearing before it fails, with belt off, grasp and shake from side to side and up and down,, If it can be moved in either direction, then replace water pump.

either the bearing is noisy and driving you crazy or the pump is leaking ,or your truck is over heating and someone is guessing this will fix it
you must first remove muffler bearing
