1998 XJ 4.0, AW4, 4X4.

I've had a bearing making some noise lately. I was hoping that it was the idler pulley. It took a dump today. Determined that the A/C clutch bearing is seized.

Thinking of just replacing the bearing. The clutch and compressor work great. Until the bearing failure, the A/C blew cold.

The bearing should be available locally through a bearing supplier. I haven't found a clutch kit locally. Complete compressor is also available.

Is it possible to replace the bearing with the compressor still mounted on the engine? Is it necessary to remove the radiator? I think I will need a puller to remove the clutch. After pressing the new bearing in the pulley, can I drive the bearing onto the compressor with a block of wood and mallet?

If I replace the clutch, what is the procedure to shim it?

If I replace the compressor, should I replace the dryer and orifice tube?
