I have been hearing a a pop clunk noise comming from my front driver side suspension sometimes when i make a sharp right turn up into a steep driveway or whatever it may be that is uneven from the road i am currently on. It does not always do this but when it does i can hear and feel it with my foot thru the floor. I am kind of baffled as to what this could be. I had all four balljoints replaced last year and i do not feel any play when i wiggle my tire up and down and side to side so i do not think it is a tie rod or ball joint even tho i am expecting my tie rod to go soon since the boot got its first tear in it earlier this year Can anybody point me in the right direction so i can fix what ever this is?

99' F150 XLT 5.4 4x4 4" rancho lift.

 

Maybe a swaybar endlink?

 

CV joint maybe, or tie rod end. Get it up in the air... put the key in the on position so the steering wheel is not locked. Then spin the tire at full turn from both sides and look for any binding. When the knuckles start to wear a bit, there is just enough play in them that during a sharp turn into an incline for vise verse the bearings tend to pop in the transaction. Indicating they are worn. On my last truck, mine would do it while reversing and turning but only if I was on an incline (example: leaving a sloped driveway)

 

possibly a wheel hub assembly...i just had to replace them on mine and it sounded like this

 

The lower ball joint assembly could be loose and on a sharp turn it will start to come out only to be stopped by the snap ring. This was happening to mine on both sides after installing new moog ball joints. The clunk was the weight of the truck coming back down and re-seating the lower ball joint assembly. Look at the space between the snap ring and the control arm when the wheels are turned all the way left or right. The snap ring should never be bottomed out.

 

Hmm very interesting because i have noticed a very slight pop when i first reverse but its BARELY noticeable. I just had my truck up in the air not that long ago and didn't notice any binding when i spun the tire but then again i wasn't really looking for anything besides tire wear. Ill give it another shot and see what i can come up with. What knuckles are you talking about exactly?

 

ya check your sway bar end link? i repalced mine and still got the dam clunk noise

 

The knuckles in the cv joints, where the boots cover. I thought I had a video of mine but can't seem to find it. But yeah, a full locked turn and an incline was when mine would pop. Other than that, they were fine.

I call them knuckles, but I am referring to the bearings and cage at the cv joint.

 

1. OEM sway bar link. Ends break off, usually at the top. Especially if you notice the sound when going over a bump without any other real bad handling symptoms.

2. Ball joint or tie rod .. but you'll feel noticeable handling/drift issues.

dont forget to check the idler arm and pitman arm

 

I know those links break up front. Sometimes you can't tell if they're rusted to the sleeve. They break inside and don't always fall out.
