Strange sound

[olddog66]

I’m trying to find the source of this noise that won’t stop. On 3 out of 7 stops I’ll hear this dull thump toward the front of the truck. It sounds like someone throwing a rock at a piece of foam insulation. It’s a low frequency thump or pop. I can’t tell but it seems like I feel it in my brake but that’s not for sure. Any suggestions?

check your ball joints. mine did the same thing. all i did to determine this was jack up the right front, and push and pull on the top and bottom of the tire.

That sounds like it may be it. I hope not!

yeah it really depends on how many miles are on your truck and how its been driven. all i can say is that i got lucky with my ball joints. my truck has been beaten through the oil fields its whole life and i just did the ball joints for the 1st time at 150,000mi. and im still on the original front wheel bearings at 161,000.
