Default bad water pump bearings

Mine are noisy as heck and the pulley is very wobbly. Anyone else had this issue. The car currently only has 81k mi.

I have to take it to the dealership on tues anyway to get the plugs changed, so it looks they will be replacing the water pump as well.

Just did mine at 51k miles. First thought it was a idler pulley squeaking, then the water pump started oozing something out of the bearing.

You need to get it changed ASAP. I just changed mine, found the pulley wobbly. Started digging into the housing, see attachment......

Well I picked it up last night. It really wasnt too bad. I had the water pump done, 2 plugs changed, Lt outer tie rod end, lt wheel bearing, alignment, and multipoint inpection for right around $700.

Now I just need to load my DOD off tune on so I dont have to keep putting plugs in it.
