Alternator???

['94 Camaro RS]

so my alternator has been sqeaking at a high pitch ever since winter started. i spray WD-40 on the inside of it. if you look at this pic you can see the coil on the inside. just to the right of it there is a space where i spray the wd-40. http://images.google.com/imgres?imgurl=http://www.clockwisemotion.co.uk/images/honda-k20-race-alternator.jpg&imgrefurl=http://www.clockwisemotion.co.uk/index/honda-k20-race-alterna tor.html&h=300&w=400&sz=15&tbnid=8ETSMktnp7_NrM:&t bnh=90&tbnw=120&hl=en&start=14&prev=/images%3Fq%3Dalternator%26svnum%3D10%26hl%3Den%26l r%3D%26sa%3DG but this only works for a day or two then its sqeaking again. is there a way to disassemble it so i can get grease on the shaft so it stops sqeaking??

how old is it, if you have at or near 100k, i say you better put a new one on it, its trying to tell you its time. WD40 is more of a cleaner then a lub, you should beable to buy grease in a spray can and stray some in there. I put a brand new one on mine the other day when i did my manifold gaskets. I figured what the hell, i had to old one off, and it didnt look to good, so i put a new one on. It was only like 140 dollars, its cheap insurance. The only problem i had with this new one is that it caused my belt to smoke for like 10 seconds when it was going around the pully, but i guess the pully had to break in or something.

i dont think it has more than 10,000 miles on it. im pretty sure when i bought my car a year ago the guy said it was new. i dont know of this is relavent or not but right when the cold weather started it began to sqeak and just got worse over time.

If it's squeaking the bearings are going. Last year when the alternator on my FB started squeaking I changed the bearings and brushes. No problem since.

I've never had to replace an alternator on any car I've ever owned. Always rebuilt my own.

2 brushes @ $2.00 ea
1 fwd bearing @ $20.00
1 rear bearing @ 6.00

TOTAL $30.00 (That's in Canadian $$, should be cheaper for you with US $$.

If you want to know how to do it get ahold of a GM Service Manual. Has a great step by step procedure. Not sure about the Hayes or Chiltons manuals.

I've heard that WD-40 Eats bearings

[CDNFB]

Yup, short term solution at best. If the dust seal is in good shape it shouldn't affect much. but if the seal is slightly worn, enough to let the WD-40 get past the dust/moisture seal, it will thin out the grease, and then the grease gets out past the seal. The resulting lack of grease accelerates the wear.

If you go through napa its like 120 exchange and it has a lifetime warranty... Just changed mine a month ago

so theres a core charge involved with an alternator?? gosh,i dont have the money right now!!!!

i guess i will have to pretend its the whine of a supercharger until it gets fixed. lol

I replaced mine 2 mounths ago, and it cost me about 100 bucks after i brought the core back at autozone.
