Does anyone know how often we need to Lubricate the Chassis? And where the lubrication points are located?

I notice that on "Oil Change Specials" they always say that the mechanic will "lube the chassis and top-off all fluids" But i have never seen them do anything as far as "lube the chassis" when I watch them.

Look what I got in the mail from the Dealership below. What egregious over-charging prices. I circled the 2 worst ones which have parts that cost 10$ and take less than 5 minutes to perform.



Boy, if these are the price with a coupon I would hate to see the REGULAR prices. Sheesh.
