I rock the vehicle by hand from the passenger side.I can hear a popping noise coming from behind the passenger wheel.would that be a sway bar end link,balljoints ??????????/

Sounds like the sway bar might be broken. Turn the steering wheel so you can look into the inside of the fender behind the wheel. There is a large bar that connects both the front lower control arms together, sometimes this bar breaks and rubs the ends together causing a popping noise.

Yes this sounds like A sway bar condition and yes you can Replace just the links and bushings. I would not replace the sway bar its self unless that is infact what broke. I hope this helps you out. i would appreciate it if you would rate me.
thank you

The first thing to check on a rattling noise is if going over minor bumps in the road if that is when it makes noise is a sway bar link, they make a rattling noise. If you raise that wheel up you might also want to try and wobble the wheel to be sure it is not a tie rod end or ball joint. Typically I run into the sway bar links or the sway bar bushings making the noise. However ive even seen it be a rock sitting on the strut plate.

The sway bar linkage probably came undone on one of the sides. Wikipedia has a picture of what your sway bar linkage may look like:

That is a picture of a Porsche sway bar, but the idea is the same. Make sure all bolts are tight and that one end is not missing the linkage that connects it to the spring/strut. The grinding of the brakes may be the sound of the linkage piece touching the rotor. Sway bar is a logical solution to both issues.

If that doesn't fix the issue, put the front end of the truck on blocks or jack stands and have somebody wiggle the tire up/down and side to side while you inspect the mechanical components underneath. Other things to check may be the ball joints, tie rod ends and suspension bits.

there are many possibilties. Sway bar, sway busings, shock, tire, something in the brake pad, wheel bearing, the list goes on and on. Best bet is to let someone qualified to take a look and determin what's wrong before hundereds of dollars are spent without the cause being fixed.

i think you should look at your tie rodds or more then likly its you rcv joint know to test if it;s that walk to the wheel (make sure the is straight) and give it a good kick if you hear that noise then you need cv joints hope this helps

If you aren't afraid of jacking up the vehicle, you can test to see where the problem is coming from. Jack the vehicle up by the pinch well (most newer cars have grooves cut out or that can be popped out behind the front wheels). When the wheel is in the air, try moving it side to side, then up and down. Excessive side to side movement indicates a tie rod end, up and down indicates a ball joint, and all around indicates a wheel bearing which would also be a cause for the clicking sound you are hearing.

Most auto shops will check this for you free of charge when you get an oil change, since they're trying to sell you things anyway.

Get someone to help you with this: Reach behind the front wheel just rearward of the strut and you'll find a vertical rod that bolts to the strut just below the spring perch and the other end goes to the sway bar. Hold it and get someone to rock the van as hard as they can. There's and astronomically good chance you'll feel a popping in this rod. If you do, you need to replace it. It's called a sway bar link. You'll need 2 of them and the sway bar bushings as well. Spray the nuts on the links down real good with wd40. Hold the back side with a pair of channel locks to keep the ball joints in them from turning. I take the top nuts off first, then the sway bar bushings so I can move that thing around to gain access to the bottom nuts. Then put them back in reverse order. Remember this, if you do it, no matter what anyone tells you, DO NOT lubricate the sway bar bushings. After the first rain, they'll start squeaking and they'll NEVER stop. They are supposed to go on dry.

Check your CV joint or brake caliper.

Try looking at the sway bar link on each side. If they move easily by hand then they likely need to be replaced. You can do a sort of self test by rocking the car up and down at the front fender tire well. If you can hear it clicking when you rock it, it is likely that sway bar link. Good luck!
