Changing out a water pump for a 95 BMW M3, is it a pain?
they are a piece of cake.
slight wobble is ok if coming from fan. if pulley is moving then replace water pump.
removed fan, and shield. then remove the serp belt. then remove pulley. remove the 4 nuts holding water pump. pull out. if stubborn then there is 2 threaded holes to insert bolts in and drive it out. (the t-stat bolts work perfect for that). 3
good luck
