K so I've got an 03 Lancer OZ. I had the rear driver side wheel bearing replaced. Ever since then it's made a clicking and sometimes clunk noise when I go over quick bumps. It was light, almost unnoticeable at first, but now It worse. Removed everything from trunk, and drove around. Still does it.
I lifted the rear up (jacked, not ramps) and noticed the rear sway bar bolts were almost touching the shock. But there didn't look to be any wear on either. Checked the other supports, nothing seemed out of the usual. But then again I'm not 100% sure of what to look for. I was just generally looking for sighs of rubbing or hitting. The bolts at the top of the strut towers seemed tight (what lb should those be too anyway?). No idea where it is coming from.
Any Ideas anyone? Thanks.

who replaced your wheel bearing? did they hand pack the bearings, or use a bearing packing machine? if they hand packed them, they probably didn't do it properly, if it was done by a machine they could have also done it incorrectly or possibly not pre washed the bearings before packing the grease in them. some people make this mistake and straight pack them from the box package. when they have been sitting on a shelf they collect dust.
packing them directly with grease sometimes collects the dust together and then balls it up turning the dust into a muddy grease clod. it them starts to cause damage, and before you know it your bearings fall apart in your hub and your wheel starts to wobble and comes off your car at 80 mph. i would take your bearings out of that wheel again and clean them with grease solvent, or you can always use gasoline and a toothbrush.
check for dents and wear marks if they have that you had a piece of dirt, dust, or sand already in your bearing when they wear packed. if you go to clean them and there is very little grease in them the bearings were just packed incorrectly. after cleaning them check to make sure the bearings still roll easily without having excessive noise coming from them. then repack them and put them in. if there is a problem with the bearings when you check them replace them and hand pack them your self.
packing bearings is easy, but it is a long process and people get impatient. you take a scoop of grease in one hand and with the other hand you force the grease into the bearings using a scooping motion until you see grease coming out on the other side of the bearings. you do this all around the bearing until you see grease all around the top end and bottom end of the roller bearings. then you repeat for the other one. it takes about 20-25 minutes to get them done correctly which is why people seem to get impatient. a bearing packing machine takes like 2 minutes, but people forget that a lot of the time, you have to pack standing up top first, then the bottom. then run grease around the outside for proper lubrication. some people pack it top side up and then put them in. this can result in faulty lubrication, due to air pockets in the grease tube when you pack the bearings.
