The idler pulley is located just under the A/C compressor. There is a bolts in the middle of the pulley that needs to be removed and the idler pulley can be removed. Sometimes these bolts stick and my need to be pryed off. You may also want to removed the radiator fans cow to give you some extra room.
Get a manual on your car and it will give you the procedure.
Unbolt, slide off. Slide on new part, bolt back on.
The 1999 Jeep Cherokee employs an interesting idler pulley assembly. What you need to do is:1. Remember the belt routing, it's not printed under the hood.2. Loosen the 15mm hex nut on the idler pulley3. There's a bracket that the idler pulley is connected to and a 15mm tensioning bolt to turn to release the tension off of the belt.Jeep Cherokees seem to like Premium belts best.
Idler pulleys are relatively easy to replace. But if squeal goes away after 10 min, it may simply be that you need to tighten up the serpentine belt a little more.
There is no idle pulley on 1995 GC's with 4.0 Inline 6. To replece the serpentine belt; 1) Draw a diagram of the existing routing. 2) Loosen the alternator. 3)Remove old belt and compare to the new belt. 4) Install new belt. 5) Tighten new belt by tightening alternator. on the 5.2 and 5.6 just rotate tension pulley to the right if you are standing in front of Jeep install and release the tension pulley and let it tighten
The pitman arm is located on the driver side under the steering gearbox. It is connected from the gearbox to the inner tie rod end and the idler arm is on the passenger side from the frame to inner tie rod end.
Try to replace only bearing #6203 2Z inside of pulley.
You can, for about 10% of the price of a new pulley, but you need a bearing press or hydraulic press to do it properly. A new metal pulley usually costs around $30, but the bearing can be obtained for $3 to $4.
Remove the old, damaged idler pulley and replace it with a new one.
Remove the belt, then remove the bolt holding in the idler pulley.
Replace the tensioner assembly as one piece.
There is no part called an idler sensor.
I believe there is an idler pulley which keeps the belt tight on the 4.0. If you are experiencing slop or looseness, I suggest you look at replacing the belt or maybe the idler is stuck or broken. I had to replace an idler in a Wrangler once.

If the idler pulley is frozen, it is high time to replace the timing belt and the idler. And while that job is being done, consider replacing the water pump and thermostat.
Take the belt off, take the bolt off of the idler pulley, take the pulley off, put a new one on replace the bolt, and put the belt back on
Are you talking about the "idler pulley"? They are quite simple to change. Loosen the serpentine belt by using a socket on the center of the tensioner pulley, slide the belt off the idler pulley, use a socket to pull the center bolt of the idler pulley and replace the pulley with a new one.
I suppose you could, but these idler pulley's are not that expensive to replace the whole thing. They do fail (a weakpoint for these motors), but usually give some audible warning, also check for loosness. Do your best to purchase the steel idler pulley and the bearing will come with. When these items do "let go" they can leave you stranded, if you see a problem replace as soon as possible. Hope this helps. "G"
