Clunk when driving over potholes. . .

I have been hearing this for a couple months now. I'm driving like 5mph, and when I stick my head out the window I can hear a "clunk" sound when I hit a pothole or bump. It sounds like metal hitting metal. At first I thought my skid plate was loose, but it isn't. I think it's coming from the front drivers side, but definitely from the front of the truck.

Positive it is coming from the front?

I had the same problem, swore it was coming from the front, but after a year of trying to find it, I changed my focus to the rear.

This was the culprit....



Vibration traveled up the frame rail, and led me to believe it was up front because I could feel in the floorboard right under my feet.

 

I don't know, maby. I do have 106k miles on stock shocks... 5100's are sitting in front of me as we speak. Just waiting on the AAL's to get here to install all at once. I hope thats it lol

 

I swore up and down for almost a year it was the front. After torquing the front over and over again I decided to check the rear. I immediately noticed the wierd rub marks and oily build up on the driver's side rear shock.

I haven't heard the noise since installing my 5100's on the rear.

 

If this is the problem, my truck is fooling the shit out of me. . .

 

was that the problem?

 

I have the same clunk from the front drivers side as the OP. Its definitely from the front, I hear it when i go over sharp speed bumps, potholes, etc... My guess is the CV axle since there is a lot of back and forth play.

 

Ok, the shocks were not the problem. I now have 5100's all the way around. Still the same sound, and now it makes a clink sound when first applying the brakes. Brake pads are almost brand new.

 

I am gonna check with butler toyota in macon to see about getting the tsb work done on the steering column. I'll let you know if they fix it. Hopefully all they will charge me is the 'good will' warranty fee. I took it to them when it was still in warranty and they couldn't figure anything out. I'll make sure to remind them of this.....

Where in GA are you?

 

mine makes a "click" or "clunk: sound when applying the brakes. totaly normal.

 

Mine makes that clink sound as well. I took the tire off and grabbed the rotors and rotated them forward and backwards and I got the sound. It was the brake pads shifting slightly in the caliper. The clink is the pad hitting the caliper. It doesnt seem like it will hurt anything so I let it be.

 

Conyers/Covington area. Yeah let me know what happens. I'm really not too worried about it now. It's been going on for about a year now, and nothing has broken.

I miss Macon I used to ride at ICR Mx every weekend.

 

Oh right on. When did they close?

 

Last year I believe. Well, thats when I heard about it.

 

I hear the same click/pop sound that sounds like it is coming from the front end. Usually happens under acceleration while turning. I have given up trying to find it. If it's something serious I hope i am going slow and the truck is still under 100k miles

 

Clunk when driving over potholes, check sway bar bushings and end links, front and rear, and even if they look good and don't seem to have any play, they can cause this problem, if you rule out everything else, it is worth a try just to replace all the sway bars rubber parts, not that expensive, and I have cured more than one pothole (or just plain bumpy road) thump by doing this, even when they didn't seem bad with a visual inspection.

 

steering colum play...

 

I have the same damn prob. I made a video and there does seem to be play in the steering. Had a buddy try to see where the pop is coming from and he said its from the middle of the truck. Not the IFS.

 

its steering colum play...under your colum by the floor board

 

If the clunk is eliminated by applying a slight amount of brake, chances are it's the same issue I had.

Brake pads rattle in the caliper, Toyota has a TSB for this and some very expensive special grease if you want to DIY.

Ususally happens after pad begin to wear and make the truck sound like a old "Bucket of Bolts" going down the road.

I got the grease and applied it ..... Truck is now whisper quiet
