Very straight forward, easy job.

Take the belt off, unclip the wire, and few bolts and it will come right out.

Dont replace it with a crappy autozone/orilieys rebuild. You will just end up doing the job again soon. If the one thats on there is the factory toyota one, have it rebuilt.

Remember to disconnect the negative battery cable no need for unneeded fireworks.

Maybe time for a new belt as well.

good point wyoming

Additionally, for a bit more oomph the 95-96 Jaguar XJS alternator is a direct drop in. This is the best prices I've found.

Only if your drawing the extra current all the time .

Also the circuit protection needs to be addressed as well if not you will open the protection when your demand exceeds the factory limits.

Although it never hurts to upgrade the electrical systems on these trucks

Also, if you buy a factory Toyota alternator or are manufactured with Toyota Warranty like Toyota Parts Zone sells, make sure you keep your old Toyota alt for core refund.
After-market alt will not qualify for core refund for Toyota-Warrantied alts.
