I hit bumps, and it sounds like there is loose coins in one of my wheels or something, any ideas??

 

Any truck info? On a different vehicle that made the same type of noise, the culprit was the ball joints. The only real way to find out is to jack the truck up (USE JACKSTANDS!), and try to rock each front tire. Should be no movement when push/pulling at 12 o'clock and 6 o'clock, if so, you have a bad wheel bearing. At 9 and 3 look at ball joints and tire rod ends for movement. There should be none.

If you are not comfortable in your judgement, an easy, quick way to find out whats wrong is to take the truck to an alignment shop and tell them you want an alignment. They will let you know if anything is wrong in your front end.

I am pretty sure this is a chasis condition as it only happens on bumps. Does you steering wheel shake, or truck shake after hitting bumps? How are your tires wearing? How long has this went on? Is your truck 4 or 2 wheel drive? We really need more information on your truck.

 

My truck is a 2003 5.7L hemi with 55k on it, drives nice ans straight, no shimmy or shake, tires wearing all 4 very even, just an annoying "ching ching ching" sound when I hit little bumps, no clunking noises, just little metallic noises

 

Have you checked the interior of the truck, under seats, glove box, under rear seat for maybe tools or anything that could be clanging together? If coming from the outside, as stated before, jack truck up, get under it and start pulling, and trying to move stuff to replicate the sound. I was under the impression that it was a loud rattle, marble in a can type noise.

 

Check your shocks. I had a rattle in the rear right of my Grand Cherokee a couple of months back. I checked everywhere and it ended up being the bottom shock bolt nut had worked a couple of turns loose (yeah, I installed the shocks mayself ).

Sounded just like that, like if a can of coins was rattling on bumps.

 

Looks like I'm gonna be under my truck today LOL! Thanks guys!

 

I FOUND IT!!! Looks like the previous owner had helper air bags installed in the rear, but overloaded it and cracked/broke the leaf that the bags were installed on, so the bags were just banging around in the back against the leaf springs.

 

That doesnt sound good. So are you installing new bags or scraping them?

 

Looks like they added 1 leaf as well as the bag, so right now, I'm tossing the bag out, which will bring it back to semi stock status, minus the fact that it has 1 extra leaf in there.

 

and you never noticed this when you checked the truck out prior to buying it???
