I was doing my usual fluid checks today, and decided to check for play in the accessory drive idler and tensioner pulleys, since I recently noted a faint bearing noise.

Both had a small amount of perceivable wobble... maybe 1/64" at the pulley flanges... is this still accepatble, or is it time to replace them.
The tentioner was replaced once in the 164K this engines done.

Whilst at it, (just for grins) I checked the water pump, alternator (both replaced since new), and the power-steering pump for play.
The water pump, and alternator have no play, but the power-steering pump has about 1/8" of end-play... I'm guessing this is not normal.
I do not have any PS fluid leakage at this point.
Am I up for a new PS pump?

 

A little in /out play on that pulley seems to be normal. I don't know how much is to much, but as long as there's no wobble..I meant the power steering pulley. Don't think any wobble in the idler or tensioner pulley is good. The idler will start screaming when it gets bad enough tho.

 

Also, check your harmonic balancer to ensure that the rubber isn't going bad.
