I'd like to think the bushings are good or else they wore out after less than 6 months.

Well, I'll take a look at the alternator area tomorrow and see. Thanks!

I think we need a video of this sound. My first thought was the leaf springs or shackle bushings.

You sure it not just mag light rolling around under the drivers seat?

I'll need a go-pro for the video but I can possibry do that this weekend.

I wish it was a maglight!!

Did you make sure and weld the frame tubes in straight and take a cross measurement?
Not just front to back. If they are in crooked the bushings will wear very fast. Good luck BBP.

Nah. Didn't have anything to run across tube to tube. I'll have to check the bushings.

Soooooooo....I went thru and found all my body mounts loose.....!





Tightened them up and guess what???



Nope. Still have noise. Lol. Also, because I've taken a few springs out of each pack I went ahead and made some Teflon blocks to fill in the gaps and keep some tension on the leafs. Still have noise.

I can feel it thru the floor boards at times as well. Also, there's no interference between the alternator and steering shaft.

Hey BBP, I was thinking about doing different engine mounts in my 4Runner and it made me think about your problem. Do you have a torn engine mount? Or could it possibly be a torn T-case mount? I would check those to see as well. Lockers, big tires, and low gears put strain on those old rubber mounts. Hope this helps and good luck again.

I will look all the mounts over. At this point anything and everything is suspect! Lol. I have a rockstomper poly mount on the drivers side and a brand new OEM mount on the passenger side. My gear drive tcase has the bigger V6 mount and I bought brand new 10 years ago

Thank you!

Think I figured it out. As most suggested it was just spring noise. So, with a can of WD-40 I hosed the spring packs down and viola! no more noises. So, we will see if the noise comes back after some time.

Glad you got it figured out! My 86' 4 runner SAS just started doing the same thing this winter after dd it for a year and a half with no noises. It makes that thunk sound when turning either direction, sometimes I could feel it through the floor boards. I'm running a hybrid RUF pack though, probably doesn't help that I still haven't installed any leaf spring clamps yet, lol. Anyway glad you were able to figure it, I'll have to give that a try!

It's starting to make noise again, I think the wd40 is wearing off

I had a similar noise after installing my trail gear kit and hysteer. I figured out it was the steering stabilizer would rotate my steering arm and was making the tre clunk. Caused premature wear, the stabilizer is gone now. See if you can rotate the steering arm easily.

I'm not very happy with my steering stabilizer either. It groans obnoxiously on occasion. Piece of crap. I cannot "easily" rotate the steering arm. It takes some effort. I'll keep an eye on the tre's though, thanks!!

Entire front end was rebuilt prior to install.
Why would it be will bearings when the sound went away after WD40 sprayed on the springs helped?

My springs are clangy too. Ill have to try the wd40 trick.

BigBluePile

iTrader: (3)

Sure wasn't.....

Muffler bearing was a little loosey

Indeed. It lasts a little while and then you'll have to spray again. Grease would be better I suppose. It's a good way to troubleshoot though. If I put the other springs in that have the Teflon pads, I'm willing to bet the noise goes away

I know this is an old post.

Did you figure this out.

My shackles tend to loosen but the presentation is different. Though we run different set ups.
