As long as the 1999 has the 3.5L engine, yes.
Found the problem. Rust on the pulleys. Wire brushed the rust off no more squeal.
On the passenger side of the engine, toward the front of the side. Near the alternator.
probably it can be changed but if you change the whole alternator you will gain a new alternator for your engine in opposite of changing only the bearing which is not guaranteed.
Alternator belt needs adjusting
Sounds like a slipping alternator drive belt. Adjust in accordance with manufacturers instructions.
Sounds like a loose or worn belt, alternator or fan tends to do that when they get worn or loose.
the belt or belts need tightening, most likely the alternator since it puts a lot of drag on the engine and will speed up more slowly than the engine can.
Check the belts. The most common cause of squealing is a worn or loose belt on the front of the engine.
Because the alternator puts a load on the engine of several horsepower, the belt must be very tight. However, if it is too tight, the bearings of the alternator shaft will wear out quickly. To tension the belt properly, adjust until there is about 1/2 inch of play in the center of the longest span. If this does not stop the squealing, the belt may have been glazed from being too loose, and needs to be replaced.
You need a new belt, it has nothing to do with the battery, but rather the new alternator. The belt is probably old, dry and cracked so it is slipping during the acceleration period due to the load from the engine.
Belt loose or worn out. Also possible a bad water pump, or bearing failure in the alternator or serpentine belt idler.
