Just replaced the motor for a 2003 Sequoia and it cost $250 for parts and labor.

Toyota never made a manual version of the Toyota Sequoia.
It has a timing belt that should be replaced every 90,000 miles.
The most unusual tool need to replace the front wheel bearings on a 2001 Toyota Sequoia 4WD is a wheel puller. This tool is needed to remove the brake disc from the wheel. It can be rented at a tool rental business or bought at an automotive parts store.
