Could you guys take a stab at what might be making a 'thwack' or clunky sound in my front end? It sounds like it's coming from the front left wheel. It's not engine related. The frequency isn't related to rpm. It also doesn't seem brake related since whenever I apply the brakes it doesn't affect it.

Even at 5-10 mph it thwacks. It sounds like it's each revolution of the wheel so it's speed dependent.

 

Jack up the left front and put a bar under the wheel and go up and down and then grab the tire for a side to side. Mine sounded like that when the ball joints were bad.

 

Thanks man. Is it ok to drive a little longer when it's making that sound if it's the ball joint?

 

Mine was 'clunking' for over a year..... before I talked to a garage about fixing it. I still waited another 6months before I fixed the ball joints. I saw no tire wear what so ever during that time. I was not worried a bit about driving my truck..... still drove it hard (pulled) the whole time.

Look at the tie rods and the rubber bushing for wear.

 

my truck wood make a clunk when the hubs were locked in turned out to be that the ringgear in pininon were wiped out

 

Could also be your sway bar link bushings being bad. When does it make the noise?

 

I agree with Jody.Several things it could be but when we here clunk it is usually sway bar/drop down link bushings.

I replaced the both the front and rear sway bar bushings and still had the clunk. It turned out to be the body bolts.

 

Can you explain what you found and what you did to fix them?
