I have a 1994 Path, 4x4, Auto that's suffering yet again. She's getting old with 258,000+ miles, and I'm suspecting that there's a bearing going out in something like the water pump, or alternator, or something...
I'm getting a whinny windy roaring noise under acceleration (anything over 20 mph) and a power loss. She's having trouble getting up to speed, and uphill is harsh on the ol gal. Considering I'm going on a 3,000 road trip over two mountian ranges while towing over 5,000 pounds in a mere matter of weeks here, I am a bit worried. Do any of you all know what could be going on here? - Aaron 1994 Nissan Pathfinder (232,900 Miles 12/18/06, 250,000 Miles on 09/25/07) 1988 Nissan Pathfinder (Dead, but you can now buy parts!  )1967 M52A2 5-Ton Tractor Truck (6x6, Multifuel) 1953 M38A1 Army Jeep 1952 M38A1C 106MM Recoilless Rifle Army Jeep

Pick up a mechanic's stethescope and see if you can isolate the source of the noise.
If its a bearing up front on the engine, it should be relatively easy to pinpoint it with that tool. ------------------------------------------------------------  <--Click Me!"As a lion is to a cat, so is a mastiff compared to a dog."

If I had the time off work I would. But I don't. I think I'll have to drop this off at the dealership closest to work and see if they can help.

I'd ditto on the fan cluth if it sounds like a roaring noise of lots of air moving. I've had several fan clutches go out and this wind noise is the tell tale sign.
Later, Matt My Jeep, It's like a big sneeze during a really good piss! Breasts are great!! After all, you can't motorboat a personality. |

So I went out on break, checked the big white fan, and this thing doesn't turn well.
Turning it to the passenger side was sluggish. turning it to the drivers side, hit a hard spot, then was really hard to turn. Shouldn't the thing move freely???  - Aaron 1994 Nissan Pathfinder (232,900 Miles 12/18/06, 250,000 Miles on 09/25/07) 1988 Nissan Pathfinder (Dead, but you can now buy parts! )1967 M52A2 5-Ton Tractor Truck (6x6, Multifuel) 1953 M38A1 Army Jeep 1952 M38A1C 106MM Recoilless Rifle Army Jeep

I called up the local Nissan, and ordered one up. They said they had a bunch on hand since they're failing on all the older nissans, but they ran out a little while ago...
The earliest they can get it is Thursday morning. So I bumped my appointment out to noon on Thursday. - Aaron 1994 Nissan Pathfinder (232,900 Miles 12/18/06, 250,000 Miles on 09/25/07) 1988 Nissan Pathfinder (Dead, but you can now buy parts! )1967 M52A2 5-Ton Tractor Truck (6x6, Multifuel) 1953 M38A1 Army Jeep 1952 M38A1C 106MM Recoilless Rifle Army Jeep
