One of the pulley clutches is wobbling (it broke) I need to replace it, how?

This either had a bad tensioner or your belt broke. There are several pulleys and if they start wobbling, almost anything can happen. You should be able to manually grab and rotate each pulley to check for wobble and roughness.

The tensioner is a spring loaded bracket with a pulley.

I doubt it can be repaired without replacing the clutch. It would depend on what the cause is. If the bearing is failing the clutch would have to be replaced.

Power steering pump shaft seal is leaking, You can add a table spoon of DOT 3 brake fluid to the steering fluid to condition the seal. The A/C pulley wobble is a compressor clutch bearing problem and requires the correct puller to replace. Replace the clutch as a unit, to avoid messing with the bearing. Replace the belt if the steering fluid leak stops. If the brake fluid trick does not work, replace the steering pump. Parts and labor will be better than 200.00

You can go to one of the online auto parts websites and look up the water pump to see if it looks like your pulley. Or visit a local store.
If the water pump pulley is moving, the bearing may be failing which would require replacement.

Unfortunately, if you don't have a machine shop, you will have to replace the entire power steering pump instead of just the pulley.

But you should also check ALL the pulleys to make sure that something else was not damaged when your pulley came off. Check for any wobble in the shafts, especially the water pump. If you have any wobble then that component should be replaced also.

Good Luck!

Hi, there must be a problem with one of the pulleys. Check each pulley for play. If any pulley can wobble, the belt will come off. It's probably falling off and they breaking after getting caught up in the works. Let me know what you find, and I can provide repair advice.

The fan clutch is connected to the water pump. The harmonic balancer is the crank pulley. If the fan clutch/pulley the fan clutch is attached to is sloppy than the water pump is bad.

First check all pulleys for wobble or looseness. If all pulleys are OK, use the below diagram to put the belt on all pulleys except alternator. Put a wrench on tensioner pulley and pull down until the belt will slip onto the alternator pulley. Check that belt is still on all pulleys before starting. If belt comes off again, one of the components is failing (usually an idler, tensioner or water pump wobbling).

When the AC compressor kicks on, an electrical load is placed on the alternator and the drive belt that turns the alternator pulley, if not tight enough, can cause the belt to squeal. Replacing the belt should help with that noise if the belt is stretched from wear. The screeching noise can be from a bad idler pulley, a bad belt tensioner pulley or a bad alternator pulley or a failing clutch on a very old ac compressor and rarely a water pump pulley. To check pulleys remove the drive belt and turn them individually to see if they can be tilted up down or sideways with play in the "bearing" of the pulley. Also, you may wish to visually inspect the clutch on the ac and look for melted black rubber around the bolts that secure the clutch to the compressor (stinks,smokes and melts these rubber areas if ac compressor clutch fails).

Turn the motor off and move the pulley by hand, if theres alot of slop in it, change out the water pump.
