WHAT WENT WRONG -- wheel bearing replacement.

What is your question?

My husband and my father-in-law just replaced the two front bearings on our 2008 Scion xD. Standard procedure, took of the wheel, the rotor, the brake pads, the caliper, disconnected the ABS sensor, the lower arm, the upper bolts, and the tie-rod end. While they were removing the lower control arm, the boot for the lower ball joint was damaged on both sides. Finally got the knuckle off (after much rust). They used a press from my FIL's work (he is an airplane mechanic) and pressed in a new bearing and hub into the knuckle. When they spun the knuckle independent of the car, they sounded smooth and ready to go. They also purchased and replaced the lower ball joints entirely, as a boot is not sold separately for this make/model (too small). They put everything back together, and now the vehicle sounds like BOTH bearings are bad. What happened? Note: my husband is not an amateur, he has been working on cars/trucks/motorcycles his entire life, and like I said, my father-in-law is similarl

What makes this problem better or worse?

Replaced the bearings, sounds like they're both bad

How long has your 2008 Scion xD had this problem?
