alternator pulley bearing decoupler

[piotrowr]

A local shop informed me that this item is what's causing a repetitive clunky noise when the car is put into drive or reverse. They said it would eventually need to be replaced but is it potentially covered on our extended transmission/drive train warranty? I have 56K miles.

What does the ADP have to do with the drive train? If yours is on the way out, I would think you would want to replace it before it fails.

My bad, not related to drive-train but did read somewhere about at TSB for it. Any info on that?

Not that I've seen.Perhaps other may know. In fact, this is the first post I've seen about the ADP.

The shop wants $355 to replace. I find the part on Rockauto ranging from $80-115. Sounds like they are charging 2 hours labor.

Or they are charging more for the part, which is quite likely. The alternator may have to come out since space is a bit tight to get the two tools needed to release the pulley...one socket to hold the shaft and a second to release the pulley. Probably more than 1 but less than 2 hours.

Another shop just said 1 hour labor $100 plus about $90 for the part. Big difference. I had it there before and probably trust them better anyway.

Ya, that sounds reasonable. It's not a big job.
