Fzj80 underside front end rattle when going over bumps (1 Viewer)

I had the same issue. when i changed my shocks and springs it went away. as a few have said before my guess was the shocks were too old. good news is that shocks are relatively cheap. good luck

Funny enough, when I changed out my shocks springs and radius arm bushings to support the lift, the issue went away primarily on my daily drive. I drive to and from work with my car in Los Angeles (I know, it's a very inefficient idea but I love the car) and the roads here are so bad in certain places that it would create this annoying, harsh rattle from my from driver's side wheel/suspension area. Most recently I thought it could have been the radius arm bushings that connect to the chassis but I replaced that too and still nothing. Good thing is I don't get this rattling noise when driving down the street anymore but when I'm off-roading it's most definitely there especially on washboard roads. I'm at the point where I'm going to replace my panhard bushings and if that doesn't work I'm thinking of replacing the burfield and perhaps my hub. I really don't know at this point.

If all else fails, could be a crack in the frame, see this post:

The noise

Did you replace the trunnion bearings? Yep

When my 94 was stock with the stock running boards the bolts/brackets attaching those would bounce and clank like crazy at certain times. Both sides. The worst was the passenger side against the cat heat shields.

I had this. Rattling cat heat shield drove me nuts.
