I did a few searches but didn't come up with anything

But here is my issue. Upon letting up on the gas and letting it coast, I get a rattling noise. upon acceleration it stops. Drive shaft, U joints? Something else? I am not a mechanic so be easy on me with the terminology


Second, upon acceleration there is a slight noise maybe sounds like coming from tranny, it only occurs in the very first second of the acceleration, the more gas I give it the shorter the noise lasts. Kind;ve a little clunky sounding when accelerating for that first half second.

I know this is kind of vague.

 

So, have you ever had the front drive shaft rebuilt or rep;aced to prevent it from failing and taking the tranny with it, how often do you grease both drive shafts?

 

I just got the vehicle several weeks ago from a dealer. so I have not had much of anything done to it, I was going to go through that list in the "major service" thread in a couple weeks. After next Pay check. I cant be sure of what has been done to the vehicle for maintenance.


I just went out and checked it looks brand new and does have the greaseable joints

 

I would not drive it if it is making noise and hasn't been rebuilt or you could loose your tranny and then you will be in trouble.

 

It has been rebuilt, it has the grease able joints

 

is it a rattle or a thump? all of these things make noise when you get on and off the gas. It just has to do with the fulltime four wheel drive, there is a lot of play in the drive lines.

 

as for the first symptom its a rattling noise, seems like it my be coming from the suspension the more I think about it, as opposed to a drive shaft or something of that nature

 

For the rattling, there's an outside chance it could be your exhaust. I had a heat shield on one of the cats start to rust at the seam. At lower RPMs, it hit the right resonance and would rattle like crazy. When I accelerated and hit higher RPMs, the rattle would go away. Might not be your problem, but thought I'd throw it out there.

 

My '03 has a crazy rattle as I pass through 2500rpm or let off the gas and it comes back down. I've traced it to the pipes (ACE?) running just under the fan, taking a turn near the oil filter. Either they rattle by being too close together at a certain point, or it's a loose mounting bracket and screw along the path of those pipes. I can completely eliminate the rattle by holding the pipes together (watch your hands - FAN!) and will investigate further soon.

 

I just got done rebuilding my front prop shaft with new u-joints for a knocking/rattling noise between 10-15mph under acceleration.

I know that's different from your scenerio, but what I found in the driveshaft was that there was a washer with a small hole in the center that was freely tumbling around in it. I've only seen it referenced once before and noon gave the guy any input. I took a peice of tubing and just pushed the washer against the rear part of the prop shaft. Haven't had the problem come back.
