My throw-out bearing has been making noise for a few years and is getting louder lately. I am gathering info on what I will buy while my mechanic is in there besides the clutch. My question should I replace the alternator even though it is fine? I have 108K on a 04 'S'
I plan on replacing the serpentine belt, tensioner and idler.
I think a kit would be nice and I noticed Way has a kit but I wouldn't need plugs, so it looks like I will have to purchase each piece separately.

 

My alternator went out after 103k miles. If you're getting all of the other work done I don't think it would be a bad idea.

 

No I wouldn't replace an expensive alternator just because you have the car apart I've seen plenty working with over 200k. But also I don't even go to that side of the engine when I do a clutch.
I just pull the subframe then pull the trans.
So common things I do when I do a clutch:
rear main seal https://www.waymotorworks.com/rear-m...0-r52-r53.html
clutch fork bushings https://www.waymotorworks.com/clutch...-cooper-s.html
Powerflex control arm bushings https://www.waymotorworks.com/powerf...shing-kit.html
P/S lines if any are leaking https://www.waymotorworks.com/r50-53...sure-line.html
Steering rack bushing https://www.waymotorworks.com/powerf...k-bushing.html
front sway bar bushings https://www.waymotorworks.com/powerf...-bushings.html
supercharger inlet gasket https://www.waymotorworks.com/superc...et-gasket.html

Again that is when I pull the trans only. If you are planning on pulling the whole thing engine and trans that would be a bunch of other things I would do as you will have access to much more. I would talk to your mechanic to find out his plan
like supercharger oil change https://www.waymotorworks.com/superc...t-r52-r53.html
oil filter housing gasket https://www.waymotorworks.com/oil-fi...0-r52-r53.html

 

Lots of good info, thanks. I told my mechanic my throw out bearing has been making noise for a few years and is getting louder and would like to get that done and while "you're there replace the clutch". The belt has never been change in 15 yrs., so might as well put in a kit there as well.
The supercharger oil change sounds good and the oil filter gasket housing. I will have him check for any leaks. I don't don't know about the ps leaking as the dealer replaced the unit as it was recalled 2 yrs ago. They may have not changed the lines, never the less I will have them check.
