Does anyone know if the M104 serpentine belt-pulley bearing (104.200.20.28) is replaceable ?

I just called the dealer and what was once a $149 part is now over $227 !

Also, if the bearing is replaceable, do you have to R&R the whole bearing bracket or can you just replace the bearing while the bracket is still mounted on the engine ?

Thanks in advance,

What's involved/what are the steps in replacing this ?

Other than draining some of the engine coolant and removing the thermostat-bypass pipe (replace O-ring) and alternator bracket assembly, any seals, sealant or other gotcha's on this R&R ?

You don't have to drain the coolant you need a special tool to remove cooling fan clutch & pulley,belt,belt tensioner idler pully one uper alt bolt & four bracket bolt pay attention at fan bracket bolt (right uper) is different then other bolt.
