The front pulley seems to wobble a little bit.

It makes a sound like the bearings may be bad. I need to know what is involved in changing it.

Sounds like the idler pulley. It is what keeps tension on the surpentine belt. Usually a water pump will start dripping water through a small hole in pump that opens when the bearings go bad and start to wobble. You can spray some lube on idler pulley to see if it quiets it down some thou this is not a permanent fix. It will pinpoint the problem

Loud rattling sound top of engine near or below the alternator when idling, goes away if accelerator is pressed


Hello: Remove the serpentine belt, see if the waterpump pulley wobbles/makes noise when you spin it. If thats not it then start the engine, belt still off see if noise is there also while engine is running see if vthe crankshaft pulley wobbles. Also check the A/C compressor pulley (engine off, belt off) spin it by hand and check for noise and wobble. If all the previous is ok then it could be the balance shaft front bearing and or the timing chain.

Changed belt and pulley tensioner and I still have squealing sound when I step on the gas. nissan pathfinder 2005


There is quite an extensive service bulletin from Nissan regarding belt noise on this truck. It involves checking several things, two of which you have already replaced. The only remaining thing that appears to cause the problem is the one-way clutch that is mounted on the front of the alternator. Apparently they slip and cause this noise, and it sounds like this is your problem. They are a bit of a pain to change and probably expensive. Why they needed a one way clutch on the alternator, I'll never know, but that's the way it is.

I need to replace the water pump pully on my 4.9 is this difficult


Hello: That is not difficult to replace the pulley. If the pulley wobbles it is not the pulley.... The shaft bearing may be bad and that would make the pulley wobble. The pulley is held on with three bolts that have a 13mm head. If after removing the pulley you can move the shaft up and down you need a water pump.

Strange wobble noise


your bearings. thats what it sounds like to me. if it almost sounds like you have a big rock just jumbling around in your tire thats most likely your bearings. its pricey but its worth it to get it fixed. if thats not it check into your transfer case and your shocks

JUST CHANGED WATER PUMP, POWER STEERING PUMP, BELT TENSION ASSEMBLY. EVERYTHING OK FOR ABOUT 2 WEEKS AND NOW THERE IS A KNOCK OR RATTLE COMING FROM THE FRONT OF ENGINE. WHEN BELT IS REMOVED THE NOISE GOES...


the damper could be bad if it's the type with the rubber inbetween the pully and the the rest of the damper. check that and see if it is separated. if not looks like your crankshaft bearings could be bad

There is a rattling noise


Hi my name is Allen!

Let's work together and fix this problem!

Here what I need you to do first!

Remove the splash gard behind the right front wheel, this is what keeps water and other things front hitting the belts that drive the A/C pulley and alternator pulley, etc.

Next: grab one pulley at a time and see if it wobbles, if it does then the part behind that pulley will need to be replaced.

Question: Do you have the 3.0 liter or the 3.3 liter engine. I'm asking because a common problem with the 3.3 liter is the water pump bearings go bad and it will wobble causing a rattle noise.

Contact me here at FixYa and let me know what you found.

I am honored to help, and we will work together until we solve your problem!
