can anyone recommend a good workshop that comes with hydraulic press that know the proper way to change abs wheel bearing around klang valley?

For what car model? Please share more info

myvi lagi best front side bearing

if you worry can visit sell bearing shop ask them do it for you also can for the bearing related things .

Myvi lagi best is so common, any reputable mechanic shop also can do. Nowadays mostly people just change the whole bearing hub if the cost is not much. Try ask and compare, as from what i know from my mechanic if add on workmanship and everything else sometime changing the whole hub is more better in term of cost & risk (if install badly also bearing can wear out fast also)
