name that sound

[Man Jerk]

I'm getting some gawd awful clunking sound, from what I believe is the rear passenger side of my FJ60. Anytime I go over a bump, big or small, I hear a quite audible clunk. Even when I drive down a bad road (ie most MN roads) . I made a pretty good visual inspection tonight, and everthing seems to be in order. I did have to do this outside as my garage is currently disposed of, and it was 9:30 pm. I'm hoping someone can point me to possible causes.

The bushings on my leaf springs had worn out on one side and whenever I hit a bump or turned hard that way I got a clunk. It was definately a clunk. That's my only clunkin experience.

I have to agree with Eternal's input. My FJ40 was doing the same thing, and while installing my lift & new poly bushings, I found that a couple of the old stock rubber bushings had worn completely through. That wear wasn't very apparent from the visual inspections I'd made, but was blatantly obvious once I had them pulled out.

The other "clunk" I've experienced that would be similar to what you're explaining was with shocks. Make sure that they are securely fastened (both top & bottom), and that the bushings on either end are still in place.

I had a similiar experiance, except mine ended up being a axle bearing so check those also.

All very good points. Hopefully I can get to the bottom of this

Fuel tank coming loose? Lug nuts tight? Exhaust hanger worn out?

I ran over a cat once while backing out of the driveway. It was a kitten though so it was more like a bump than a clunk.

Fuel tank was my first thought. I just had it down to replace some fuel lines (lots of fun removing/installing tank alone). I thought I may have goofed it up. Nope, its up ther pretty solid.

check the pin in the center of both rear spring packs. If it is worn/loose that can let them make a pretty strong 'clunk'

 

[cruiser_guy]

Make sure the rear cross member that carries the shocks is not rusted through on that side. That'll make a good clunk.

I had a clunk like that the other day. It had been driving me nuts for a few weeks, and I couldn't find out what it was. Guess what it was, the center cap. Make sure yours are nice and tight, or they will clank back and forth. I thought it was something more serious, but now, sound is gone.

The lid to the dutch oven should be secured better

 

[dogboy2]

all of the above are good points to consider....

here's one more: how are your shocks? check the attachment points as well as the range of travel. if they are shot, you could be bottoming out the shock and thus, hearing a clunk.

Damn, this thread was started like a year ago--don't you guys think he would have figured it out by now?

Now you got this clunk?
What ever happened with your fuel pump saga?
