Maintenance and Modifications
Fluid Changes:
I do oil changes every 3000 miles:

Pennzoil 10W-30
AC-Delco PF52
New Wheel Bearings:
When I went to pack the wheel bearings, I noticed the original bearing races had a slight blue tint on them where the bearing would run on the race. This is a sign of heat and lack of lubrication. To be safe I decided it would be best to replace the bearings. The original GM bearings were Timken, which I believe are one of the best bearings. I purchased a full set from Autozone. I am not a fan of Autozone, but at least they do stock Timken bearings at a reasonable price.

I change transmission fluid and filter every 40,000 miles:
