I have a weird rattle or metallic noise coming from my Jeep when I hit dips or cracks in the road. Is it the suspension "slapping"?

I am paranoid it is my wheel spacers or something? I went over a washboard road and not a sound. I went over a speed bump and not a sound. On cracked pavement in my parking lot it rattles as my wheels go over them...

I checked torque on outer lugs and they are good. Can't pull off the wheels since I have no garage. But rocking the jeep back and forth doesn't produce a sound. I tried to jiggle my exhaust tip as hard as I could and there wasn't a sound. Nothing loose in engine. I do have some loose hard stuff in my center console and I can hear it when I turn, but it shouldn't make a noise when going over a small bump?

Any thoughts? Maybe I'm not used to having a Jeep, since I am coming from a WRX. I'm deaf so I can't pinpoint where the sound is coming from...

 

are those all the mods listed in your sig? any sway bar disconnects ?

 

The only mods not installed are the flowmaster and IPF lights, since they haven't arrived. I am running with a straight pipe out the back from the stock exit behind the axle. It's held in there good.

What you see in the sig is what I got. No disco's.

 

You did remove the rotor clips before installing the spacers didn't you? I'm wondering if there is a lug nut rattling around in there (not sure if that's do able). But go to a parking lot and take the wheel off if you have to. It's certainly worth if if a spacer is walking loose.

 

The rotor clips have been removed (the things around the stock lugs?).

And all the lugs were tightened the same as the outer lugs with loctite. I couldn't figure out how to use the torque wrench so I tightened them the same way I would tighten my wheels up, which is pretty damn tight.

 

The thing is... going over washboard roads and speed bumps isnt producing the sound. Only when going over small cracks or sharp angles (fast suspension compression/rebound).

I am going to check my radar detector to make sure that it isn't the problem. Also. I will go now and make a short video and upload it to mediafire, where you guys can click and download it.

 

here's the video. I took a relatively flat road and then made a left turn and went over a speed hump real quick. Then for the last few seconds you can hear all the rattling while I go over the cracks in the parking lot. console and glove compartment has been emptied, radar detector removed, etc...

Anyone? I should be home for xmas day, I will pull off my wheels and check the spacers. But anyone have an idea what this could be?

 

I didn't see your video, but from what you describe, it seems more like something loose in the drive line / suspension... I would simply have it checked by a mechanic in any garage...

 

I had a similar noise after I installed my spacers but it turned out to be the bushing on my Full-traction adjustable track bar needed more grease and tightening. I've been running them now for almost two years with no issues.
