Whining Alternator
My alternator has begun to whine. Is it ok to spray a little wd40 to see if it lasts a little longer? Is there a rebuild kit available, or is replacement the best option if it will not quiet down?
Thanks!

What year? Is there any information on the alternator case that you can read?

Without knowing the year and which alternator is on the car presently it's difficult to recommend changes. If it were an early car with anything other than a CS144 then it might be an opportunity to improve the charging system.

Here's the thread. Disregard the '86 conversation and go down a few posts where the CS144 is mentioned.

If you're concerned with originality and you can determine that it actually is the OE then I'd rebuild/repair what you have. An original would be stamped 1105585, 1105450 OR 10479865 I believe.
