When to Pack C6 Wheel Bearings
I'm packing the wheel bearings on my dd tomorrow (I do it every 30,000 miles or so) and wondered how often this should be done on my C6.

trying to estimate the life of them, is like trying to guess the life of a light bulb. lots of different variables affect them..........track events, etc. they are NOT cheap. the abs sensors are built in them.

Ive seen them last 60,000 miles and 200,000 miles. Like previously stated. Depends on how there used and abused.
If they get excessive slop in them, it time to replace them. There easy to check.

You can not pack them, only replace them and they are real b$tch to do. It take a torx 55 socket and the bolt corrodes to the hub. My car has never been in salt and very little rain, so we cant blame the salt they put on Wisconsin roads during the winter.
I installed the SKF performance ones. If you get them from Pfadt, they include new bolts. You will also need new CV joint nuts as well when you do it.
Front and back are the same. If you want longer studs, this is the time to do it because only stock length studs will fit if the hubs are on the car.

Unless your buying high performance hubs for sever duty track use,,, the ones from AUTOZONE work fine and are a direct fit. There NO where near that price.BC

Why did you replace the originals?

Just for grins I checked . They show different bearings for front and rear. Timkin @ $175/$165, ACDelco @ $275/$158, SKF @ $246/$223 National @ $219/$210.

Here are pictures of the front and rear hubs. There off a C5 but C6 are similar:
FRONT:
The actual wheel speed sensor:
Rear hub:
How do you check the bearings: Jack the rear or front wheel and push pull at the top and bottom of the wheel. If there is excessive slop in the bearings, it will be very evident. When a bearing is new, it will be very difficult for you to detect the bearing clearance without the use of a dial indicator
If you can detect slop, the bearings are wearing.
If you are surprised at the amount of slop, change them out.

Under average use they will last a very long time. Easily go 500k as the assembly used in the Vette is over engineered for the application as are most Timken tapered package bearings. (as long as it's a genuine Timken product.
