You are probably going to have to get your parts from the dealer. I believe they are like $15 a piece. Replace both of them if you are going to take the time. The idler and the belt you can get from Napa. The tensioners are pricey, I want to say like $100. You will need to know whether you have a 105A or 130A alternator to get the correct belt. Since you live in FL and you are spoiled with nice weather, id just get your idlers and drive to Napa and get your other parts and do it right in the driveway......that's what I did. Take a 1/2" ratchet and a pipe to relieve tension of your belt, pull it off and swap parts. Refer to the diagram on the plastic cover under the dash to put your belt in correctly.

I got the tensioner for like $60 at schuck's/O'reilly's. Just make sure you have a decent sized breaker bar or ratchet for the tensioner. I didnt remove the fan shroud from my truck and it took me like 20 mins to change the belt, tensioner, and idler pulley. I dont know how much different the LBZ is, but on a LB7 it is simple.

Not 15 each.... Bearings are 5$ each. Take idler off knock the bearing out. Take it to a bearing place, there is an ntn bearing replacement. Do all 3 if your doing them. IMO it's a waste of money to buy the pulleys unless they are damaged from the bearing exploding.

Yeah i know...but didnt have the time to mess with it or a close place to take the idlers to. I would have had to drive 30 miles one way without a truck

I kept the old ones to change the bearings in for next time.

bearing supply here wanted $15 for just the bearing, I got the pulley assembly for $19 at GM.

You can get the bearing for $3-5. Depends where you look. I found them online when someone posted the part number awhile back.
