2005 grand caravan belt chirping and pulley wobbling. when I spray some WD40 into the groove of crankshaft pulley, the chirping disappeared for a while then back. I thought the chirping cause from the pulley wobbling. is this wobbling serious? do I need replace pulley or other parts? Thanks, any help/suggestion will be appreciated.

 

The crankshaft pulley has some movement, But I don't its going to cause a problem. I would replace the fan belt and tensioner.

 

Thanks. I will take tensioner off and check.

 

solved with a new belt.

Thanks

no might be the tensioner. new belt is going to be tight and it probably become re loose when it wears in and creating issue. putting wd40 might clean out the oil too due to it being a penetrant oil.
