Have you listened to the videos of the timing chain tensioner noises yet?Farmer21 wrote:Cant figure it out. When accelating I have a squeeling noise coming from the front at first I I thought it was a pully or the belt. Had them replaced. Still making noise. Couple of days later my fan. Unsure what fan it is I think its my coolant fan. Will not turn off. From start up driving hours and turning off. I thought this was only my truck but the other day another pathfinder accelerated by me and I heard the same squeeling noise from it. The only other thing that I can think that it is. Is my coolant fan clutch. Not a mechanic so only going off what other people tell me when telling other people the same story. Can someone help thank u.[/list][/list]

Search the forums or Youtube for a video of the dreaded timing chain tensioner failing on a Pathfinder, XTerra or Frontier. You should hear it. It happens when the polyurethane shoe on the tensioner gives up and the chain is running on metal. Sound is RPM dependent.Farmer21 wrote:05 se with 78000. No I have not seen video
Ok so searching around reading some stuff and looking at videos. It doesn't sound like my problem. Let me try and be more detailed. When I accelerate quickly. Once I hit about 2900 3000 rpm it sounds as if there is a loose pully or some "change" rattling up front it will continue even after I let off for 2 to 4 seconds. Now the truck does sound one huge fan when driving. But I truly believe its two different probs. I could be wrong pleas let me know if this might be something different.

Basically the engine sounds like a big high pitched vacuum cleaner. It's very noticeable when one drives by with it...
Oh yeah after buying a new fuel pump and ball joints I don't want to be payin all that . Maybe I should use a different word then squeezing or winding. It's a very unusual sound. More like a rattle. Like a bearing or loose pully. It's gone into the shop twice and both times they said they fixed it... Wrong.tlee_20 wrote:In park free rev the truck. 4500 rpm or so. Does it sound like a faulty power steering pump. A kind of whine, not a squeal?
If so it is the secondary chain shoes. A costly repair when done properly.
Believe me, it needs to be fixed by a professional. I re did a job last week that an independent shop "attempted" to fix. Cost the guy twice. My bill was around $1400. First shop was $1100. So was it really worth him trying to save a few bucks?
Wow. That really sucksFarmer21 wrote:Oh yeah after buying a new fuel pump and ball joints I don't want to be payin all that . Maybe I should use a different word then squeezing or winding.

Ooohhhhhh. This is what I had at 2900 RPM and how I fixed it:Farmer21 wrote:Ok so searching around reading some stuff and looking at videos. It doesn't sound like my problem.

I don't hear the timing chain noise, or it's not really obvious. And it's not the same as my dash rattle.Farmer21 wrote:http://youtu.be/WgQifz2I0qQ
