A/C compressor clutch bearing

I have a 2003 tacoma pre-runner that when the A/C is on makes a thumping noise. I have found the problem on the clutch of the compressor. All it needs is the clutch bearing. Does anyone know right off what the bearing number is for the clutch?

I got an 2002 Tacoma 6cyl 4x4 with a bad clutch bearing also. Its a Nachi 593 30BGS10DST. Don't know if they are the same thought. A guy at autozone ordered me one for $18.00

 

Yea thats where I ended up getting mine. However, it did not fix my problem. What is your compressor doing? Im thinking its going to have to be replaced on mine. It only has 112,000 miles on it though

 

Mine has about the same mileage. Its been doing it for about two years. Going to sell it so i thought i better fix it. It makes the sound of a power steering pump that has gone bad. Its a big job......expensive repair at the dealer.

 

Did you just replace the whole compressor ? And did that fix the problem? Yea mines going on a year im not sure if its a pulley or what

 

Haven't finished the job yet. Will let you know.

 

put new bearing in the clutch on the a/c compressor & it sounds good now.

 

If you guys are still on the forum can you give me an update? Bones was your making a knocking noise when the ac was on? If so is that all you replaced was the bearings to which you listed the part number? And Tacoma2525 did you ever get it fixed? If so what did you do? Mine is making a knocking noise sometimes when the ac is on. The pulley wobbles some too.

 

I'm experiencing the same problem on my '02 Tacoma PreRunner. The bearing on the clutch plate is obviously wallowed out causing the pulley to wobble when under load. Replacing the bearing seems an obvious fix without replacing the entire clutch. What is the replacement bearing and who is a reasonable source, AutoZone?

 

I ordered mine from someone off eBay because I couldn't find the bearing in any store near my house. I don't remember the number on it but I can look when I get home. I haven't had a chance to put it in yet either.

 

Another thead revival. Any fixes?

 

You can test the bearing easily. Use a ratchet to hold the tensioner with some slack and pull the belt off the AC. Now spin the pulley. If it is quiet and smooth, and has no play, it's not the problem. When they go bad, they generally feel very rough when you spin by hand.
