Front Hub/Wheel Bearing on 1999 Pontiac Sunfire Question?

I have a 1999 Sunfire with a 2.2 engine automatic transmission. The front driver wheel bearing/hub is beginning to squeal - How hard is this to change? Is there any specific information that I need to know before doing it?Front Hub/Wheel Bearing on 1999 Pontiac Sunfire Question?The front hub assm. is very easy to change. After getting the wheel off remove the spindle nut (the large nut in the center of the hub). The disconnect the ABS wires ( if equiped). Now the only thing left is to remove the mounting bolts. You must be carful when reinstalling the mounting bolts because if the bolts are over tightened the backing plate will crush the bearing and before you know it you will be replacing it all over again.Front Hub/Wheel Bearing on 1999 Pontiac Sunfire Question?not hard, you should clean the rust off the knuckle before installing new one and watch out for wheel speed sensor if equiped, you might have to remove it but thats not a big dealFront Hub/Wheel Bearing on 1999 Pontiac Sunfire Question?First of all usually the Hub doesn't make a squealing noise, should sound like a low humming at first then becomes a louder grinding noise...Do these test for me...whichever wheel you think it is...jack it up and see if you can move the tire from side to side or either up and down...if the hub is bad the tire will feel loose...If it is OK, the the squeal might be coming from your brake pads..You have a wear indicator that lets you know it is time to change your brake pads..Look for grooves cut into you rotor...If you need more help email me back..
