I think the idler pulley is going out on my Jeep. I'm hearing a rhythmic sort of ball bearings in a can sound. Took the belt off and was only able to get one rotation out of it. Sprayed it down and got it to spin a little better. It will need to be replaced though. The other one will spin for days. Looks like my thermostat housing is leaking a bit as well.
So should I go with the $21 pulley or the $30?
I don't see much of any difference.

This one costs $35 but looks to be OEM.

If the budget is tight go cheap. If not go big!
What brands are they?

Top two are Goodyear. The bottom is Factory Air. My OBA secondary pulley is plastic with no problems so I doubt it needs to be metal. I think they are all metal though.
I don't think there is a 'Go Big' with idler pulley's, :lol:

I had a pulley go out and I found a perfect match @ a lawn mover repair shop for 1/2 the price .

More looking. Seems I can order a Crown Replacement for $14.99 and $4 S&H.
Anyone order form Morris 4X4 Center in Pompano Beach, FL 33069? I've heard of them before in searches but never order from them.
Anyone have an idler pulley just sitting around? :naughty:
-
unless you can get a actual bearing name for any of them i would just shoot for middle of the road

Well, with my cheapest option being $11.35 from Willy's Offroad Supply for a Omix-Ada replacement.
BTW, the stock replacement numbers;

Hey Jeffy, interesting question about your idler pulleys. (Dadgum, you do know how to research - tip of the hat.) Perhaps more than one of us would dismiss the idea of replacing them during a routine repair event.
A year ago, I replaced my water pump with a NAPA unit and three or fours after putting it back on the road, I started getting a little squeak/squeal on startup that would go away by the time I hit the end of the driveway. Few days later, it takes getting to the stop sign about a block from the house, then to the highway a couple weeks after that. By that time, I think 'idler pulley, ps pump, or alternator. Couldn't be that new water pump.'
So...replaced the idler on the rh side but don't remember why just that one. Noise went away for a few days then returned.
That's when I bought a fire extinguisher because I could just see a 'Jeep-burn-down' somewhere along my 25-mile commute.
Eventually replaced the lh idler - no joy. That's when I went to Carquest and got another water pump which fixed it.
All that to say, if I had known about this site I may have saved a little bread but, the peace of mind from having eliminated a heat generating problem was worth what money I did spend.

If the pulley it's self isn't recked,what i did is pressed the old bearing out and put in a new one. I think it cost me $5.00.

I replaced my WP years ago when it had a really faint squeak. The other guy who helped me do the swap was amazed that I could even hear the squeak and could tell what it was. :lol:
I know this time it's the ilder though. I took the belt off and rotated by hand everything but the crank. I could feel the grit in the idler. Although it seems that I was able to clean it up some so it's stopped making noise. BUT I should replace it anyway. $11 for a new idler isn't that big of a deal and I don't have a press to get the bearing out. Although I could probably figure out a way. For $3 more I don't have to waste my time and it's a 5 minute job to swap out the idler.

Any idea on what the cost would be to take it in? I think I may need a replacement as well, but not sure if I want to fuss with it in 8 degree weather.

Mechanics get estimates by looking it up in a book. It will probably say the job will take 30-45 minutes by the book. At anywhere from $65-150/hour it won't be cheap.
Really though, it's pretty easy to do. If it's not bad, I'd just leave it till it gets a bit warmer.

warmer... its 27 in Minnesota today and i was sweating when shoveling the snow from under my high centered jeep (damn 1inch tcase lowering and open front diff :rant:) after a week of -20, 27 above is sweatshirt weather... :lol:

I replaced mine a couple of months ago with a Gates unit (p/n 38042) from O'Reilly. It was all metal and seems to be holding up quite well. It was 22 bucks which I didnt think was too bad.

That's what the big 600W flood lamps are for. When I turn those on, it gets rather warm. Luckily, we've been having a warm spell and it was a nice 67* out.
