I replaced my A/C and alternator belts because they were squealing, unfortunately after I replaced them I started hearing some clicking noises only while driving, the noise stops when car is idle.

I removed the idler pulley and pulley alone doesn't make any noise.

However when I put the dust cover and the thick bearing there seems to be some wiggle room for that thick bearing to move, see pic 2. Is that normal? If I move this whole thing assembled back and forth I can hear that rear bearing move between the pulley and the dust cover.

In addition when this goes back on the car there's a bracket between the screw and that rear dust cover, but even without it I barely have space to put the lug nut at the end (see pic 3 and 4). What am I doing wrong? I know there should be more space for that screw since a bracket is supposed to be in there as well.

 

You have it assembled backwards. The flat side of the pulley should face out.

You're right, I played around with it yesterday and realized I kept trying to assemble the pulley backwards. Thanks!

 

P.S. smart to use those Nissan belts, I used Dayco and they squeal in the cold no matter how much I adjust them.

 

Just do the idler pulley delete..

 

That isn't the pulley your able to delete


i may be replace both remaining idler pulleys, when i removed em, when loosening the nuts they didnt even loosen... just spun.. just cut the belts off

 

you did loosen the nut holding the idler pulley in position before twisting the adjustment screw right?
