Pulley noise?
 

Whenever I start my '86 cj-7 i can hear a squeaking sound. I also notice
that the rpm's fluctuate while this is going on.I am certain it is coming
from one of the pulleys Is this the idler pulley? If not, how do i pinpoint
which pulley it is? How hard is it to replace?


Thanks in advance,


Frank

To be sure it's not a belt, squirt on some belt dressing. If the sound goes
away or is reduced, its not a pulley.

Thanks for the reply, I have done that, but the noise seems to surface
again.

That's an indication of a couple of things.

I'm going on the belief you have a V belt system.
Sure you don't just need new belts. As they wear
and as the pulleys wear the belts tend to get sucked
further down into the grooves. That makes for the squeeking.

If putting on belt dressing stopped the squeak it's either
an old/glazed belt or a pulley is getting worn.

Belts are cheap.
