I am trying to find out if anyone happens to know what the size bearing I need for the a/c compressor.

 

Not sure bro but why not just replace the whole thing?

I replaced mine 2 years ago and got it thru these guys...

I changed the compressor some time ago and it still works perfectly, but the bearing in the compressor is really loud because of its age im guessing. I would hate to have to change the compressor and have the system flushed again for just a bearing.

 

2.44 in. (62 mm.) outside diameter x 1.57 in. (40 mm.) inside diameter.

This was my bearing size. But from what I read, there were 2 different compressors (bearing sizes) in 4th gens.

 

So you'll be able to change the bearing while it's on the car? Once you disconnect those hoses, you will have to have the system flushed again unfortunately.

 

Yea, i'm going to change the bearing while its on the car so that I don't have to remove the compressor from the system.

 

I'm a skeptic...

 

i replaced mine.. its a *****.. the clutch doesn't like to come off after its off just replace the pulley with the bearing as a unit..

i went to the junk yard found a maxima that the pulley didnt make noise on and called it day.. been fine for like 3 years

 

You can use a steering wheel puller to remove the clutch. Shouldn't bend or maim it that way. You got lucky getting one from a boneyard (and it not squeaking) - it's a risk, but sometimes it can work out.

There are two diff sizes - this is correct. IIRC, 95 - 96 they used a diff bearing than that of 97 - 99. All I can say on why is ...
