If nothing has been replaced, None. Some replaced parts have zerk fittings, some dont. Most of them are not greasable unless you ask for them at the parts store.
there are no grease fittings on the newer cars, all ball joints and steering parts are permanitly sealed.
Lubricate ball joints through the zerk fittings using a grease gun. Clean the fittings so you dont get any dirt inside. Be careful not to blow the seals.
I service a 99 4 runner for a customer and the only zerk fittings it has are in the front and rear driveshafts/universal joints.
According to the "Haynes Repair Manual" there are no grease fittings, zerk fittings, on the 2007 Malibu. Back in the day, they referred to this set-up as "lifetime lubricated systems." Being from the old school, I believe you can never have to many grease fittings. Maybe because of the lack of grease fittings, a major front end suspension component had to be replaced in my 07 Malibu. In all fairness, this replacement was covered under the GM warranty and did not cost me anything.
Basically, 2 pieces of metal with a rubber boot in the middle that should be squishy (grease inside it) with zerk fittings on the ends.
If its a 4WD (2WD does not have zerk grease fittings), there are several zerk fittings on both drivelines that need grease every 15k miles. also inspect boots, as I found my front driveline slip joint boot was damaged and needs replacing (fun not!) Grease until you see grease being pushed out of u joints a little. safely put car in neutral and Jackstands and spin driveline to find all of them, there are at least six that I remember.
Depending upon the year, there will be zerk fittings located at several points of movement on the undercarriage. Buy a grease gun and get some marine grade grease and push the fitting over the zerk and pump it full of grease until if you can see the seals bulge and start to leak out. Wipe off the excess and call it good. You should make a point to grease these items every 10,000 miles or so depending upon use. There also zerks located at the knuckles on the front axle and at the universal joints for each driveshaft.

A zerk is another term for a grease nipple - a metal filling used in mechanical systems to feed lubricants.
