Could be the leafs in your leaf pack making noise...can put some grease between them to quiet that. Also, check the 4 bolts that fasten down the bed...had a similar noise on mine coming from the back of the cab and 2 of the cab bolts on one side were about 20 lb/ft loose. Could also be your spare tire swinging around...mine bumps into my exhaust a bit under the right circumstances. Keep us posted.

 

Also, have you checked to make sure your rear bumper and fuel tank bolts are tight?

 

Yea the rear bumper bolts are tight. I had to swap my old bumper and my tow package over to this truck when I bought this truck. Its all good and tight and I tighted up the bed bolts with an impact about a month ago and still dont know what it is. I havent thought about the fuel tank tho. I'll tackle that today if I get time. Thanks!!

 

Yeah...2 bands hold it up with 1 bolt in each...could rattle up and down a bit if they're loose probably. If not sit in the box and have a friend drive you around (do it in the country if it's to ride in a truck there) and try to better pinpoint the location.

 

Check the tailgate too. I need to adjust my latches, and when I hit a bump there's a bit of play in the tailgate and it makes a thump.

Ohh hadn't thought about that...mine's never made noise, but definitely worth checking out as well.

 

I had bad rattle for sometime, but just on bad roads (forestry worker) and it turn out to be a easy fix.The bottom passenger side of the box and the cab of the truck would hit together.I bent in the inside bottom lip of the box in and the noise is gone.

 

i also have a little bit of a rattle that sounds like my ext cab doors rattling...ive messed with them and just cant figure it out...almost like that poly spacers between bed and frame or sumtin...bed bolts are tight tho

 

My flip cover has some rattles to it when I hit some bumps but the main noise that drove me nuts was on the driver side bed. I found that the plastic inner wheel liner was loose and missing a couple of screws.

 

I've had a sound coming from the back of the truck when going over bumps since I bought it last month. The best way I can describe the noise is similar to sound of a horse gallop in a movie. A slight click/clunk sound.

Maybe we are having the same problem?

 

That sounds more like a U joint to me than a rattle...is the clunk a metallic clicking noise when you stick your head out the window to listen? (A metallic noise can sound different outside because the cab mutes it).

 

I've got that noise too. I think it's the springs. I've checked everything and its all tight.

tailgate / spare / exhaust system. Thats the most probable sources for rattles.

Anyway I think all members here can agree that our trucks are not the quietest ride out there. My brand new 2012 is full of thinny rattles and squeaks.

 

I've had this truck for 4 years in February (it's a 2005), and Alberta winters are hard on vehicles, with the expansion and contraction of parts due to the rapid temperature shift we experience here. I have a few odd little rattles (less than I would have expected), but they've only shown up in the last year really, and are all easy fixes. Worst rattle trap I've been in is our POS 2004 Nissan Armada...not a very good vehicle IMHO.

 

Have a friend lay in the box and go over some wash board lol

 

Check the shields under the gas tank and cat, they get loose and rattle like hell.

 

My bedliner used to make noise when going over bumps. Centre of liner would bounce and bang on floor of box. Some two sided tape fixed that.

 

My factory bed liner kinda flops around and hits the inside of the bed making a rattle sound. I can hear it when i shut my door too. Double tape might help, maybe i should quit being a cheap fuck and go get it rhino lined?

Ok so I added a new toolbox to the truck and the noise quieted down ALOT!! I think that the rear quarter panels were what was rattling. This truck has ridden alot of South GA dirtroads :shrug:

I also checked all the springs and sprayed them down with some hilco lube and checked all my mounts and everything is solid. Idk what it can be but I dont hear it as bad now. It sounded like a really loud clunk like the axle was loose

 

I have a rattle noice to when going over bump, pot holes, everything tight, maybe rear shocks are bad?

 

Nope the shocks are brand new with less than 5K on them. Mine was really bad whenever you go over a bad railroad crossing or hit a good pothole

Check your tailgates. Mine rattle like a mofo. Lazy and haven't adjusted it yet.

Yea I do need to adjust that. I might do that today after work.

Thanks for all the help and insight everyone!

Mine does it if I'm crossing a rough bridge, or a pothole or something. It's not really a rattle, it's more of a "deep rubber/metal squeak" that sounds like it's coming from the front part of the bed.

I can replicate the sound by pushing on the right corner of the bed and rocking the truck.

 

Ugh, I hate awakening old threads but I have this same rattle on my truck. I'll try to get a video of it tomorrow to see if mine is the same as what was on this thread.
