2000 Volkswagen Polo Repair Question
Volkswagen Polo Wheel Problem
As far as the wheel bearing. did you have it pressed in at a machine shop or is it a unitized bearing? If it is a press in and you beat it in with a hammer or such it may not be seated right.
As far as the backfiring. I am going to give you a walk through diagnostic for that situation. Just use the link below to get to it. Any Advance Auto or Auto Zone will read trouble codes for free.
