My Jeep is squealing.

Hey guys,

I had no symptoms before this but I drove my Jeep 5 miles today parked it. It sat for about 2 hrs. I then started it up to drive home and heard squealing from under the hood. It did this at idle and driving all the way home. I think it was a little intermittent. I got close to home and started to lose power steering. I put it in the garage shut it off and checked the ps fluid it was at the cold mark. After driving 5 miles it shouldn't be at hot mark, right? Serp belt looked fine to.

So what do you guys think? Is it ps pump or do I just need to tighten the serp belt? BTW: I didn't see any puddles on the floor.

Check the serpentine belt tension pulley. IT is plastic and will start to squeal just before it eats itself and starts to melt.

I had this problem just two weeks ago. On the pully and pwr steering pump assembly I notice a broken bracket. It was an easy fix, I bought the part from the dealer, $35 or so. Easiest thing to do it take off your belt, check it and check all of your pullies when the belt is off. That is how I found my problem. I noticed I had pwr steering fluid all over but it seems that it was only because the pwr steering resevoir was shaking around so bad. Now that the bracket was replaced of course the belt was tighter, squeaking went away and pwr was restored.

Ok, I'll check the pulleys. Maybe it did have symptoms if you think it's the idler pulley. I've been having problems with volt gage not staying up above 12 and when it's cold out it just drops to 0 after driving a mile. Although I never lost elec power and lights never even dimmed. Do you think it might be related? Thanks

Your volt gauge may have problems because your belt isn't properly turning your alternator. Just a thought. Mine was doing the same thing until I fixed that bracket.

Yep, that's what I thought to. I checked it out like you guys said. Removing belt and checking the pulleys. They all seem to be good except the tensioner pulley and the tension arm itself. It sounds like the bearings are going in the pulley (like you guys said). I was spinning it and it was making noise but was not loose at all.

The arm does not move freely either. I sprayed them both with PB and then with white grease also hit it with the airgun. The arm works a little better part way but as you get it to the left where it tightens the belt it has a dead spot where it won't go all the way tight and you have to move it over the rest of the way about a 1/4".

I got the belt tight and then took a test drive. I was pleased to see my gage staying at 14 with h-lights and fogs on. It also didn't drop to 9 and alert check gages. Like it would have before at the lower temps we are having here right now 40 deg F.

So I guess I want to replace both pulley and arm. How do I do this and what will the parts cost? Thanks

If it's working at the moment you are good. I would buy those parts, or just be ready to buy those parts if it acts up again.

Do yourself a favor and crawl under the front of the jeep. Inspect the bottom of the power steering pump for signs of leaking.

Ok, I'll check under the P/S pump. Thanks

I can get a tension arm assm from Adv-Auto for $63 or a orig Jeep part for $111.00 ..ouch!! How do Dayco's compare to orig? Anybody got a Dayco? Just want to make sure if I go with cheaper I get good tension on the serp belt.

It looks like 3 bolts to replace T arm. Is that all there is to it? Or is there a certain way it goes in to get tension on it?

A Gates belt will run ya $ 27
An ACdelco tensioner assembly cost $ 56

IMO any aftermarket parts for this will be fine.

That's good to hear about aftermarket for this part. I really didn't want to spend $111.00.. Yea, I looked at R-auto by the time they add the $6 ship I might as well get it at Adv Auto and not wait for it.

Any answers for this one?

It looks like 3 bolts to replace T arm. Is that all there is to it? Or is there a certain way it goes in to get tension on it?

Thanks
