Raise wheel off ground, grab tire at 6 & 12 'clock and push/pull. Spin wheel- place hand on LCA/UCA- should be no vibration. They are a ZERO tolerance bearing (as opposed to your Burb, where a little wiggle is OK)
And yes Timken, or National are the bearings to go with
The last 2 sets I changed on our cars were at 100,000 miles. The originals had no play and sounded ok on the car. I new they were done with simply because of the miles. You can easily tell a difference between old 100K mile bearings and new OEm ones when you spin them side by side off the car. It is so obvious.
