It is a huge project as it requires removal of the oil pan and the front cover of the motor.
The book pays over 8 hours in a shop for this. If you were to do it, it would about 3 times that time and maybe more as the timing chain has to be removed to gain access.
The steps below sound simple but are very involved.
I attached a YouTube video of the oil pump replacement for the 4.7 but is the same as a 3.7.

The second one is for the oil pan which also has to be removed as well.
