front end noise/clicking?

[blkmonday]

i have a 00 expedition 4wheel drive eddie bauer. 100k miles. new tires, recent alignment, new upper ball joints and tie rod ends, recent suspension change over to passive system with new shocks. also must note i have "newer" front wheel bearings but they were from advance auto and not the suggested Moog ones.

I have a loud clicking noise at slow speeds. def sounds like its coming from the front area. speeds up and slows down with acceleration. brakes do not change noise other than slow it down with tires. the truck also vibrates on the highway. i notice the tires are wearing (cupping)

is it the cheap wheel bearings? what is the best way to test for bad wheel bearings? i think they are under warranty if i can find the receipt

anything else i should test? can it be c/v joints or something?

sounds like bad outer cv joint

a bad wheel bearing will hum and get louder when you turn wheel either left or right.a bad right wheel bearing will get louder when you turn wheel to the left and bad left wheel bearing will get louder when you turn wheel to the right.

well.....i figured out the problem. last night while driving on the highway after a long day of work my driveshaft popped off! i had to call a flatbed to get it home. i crawled underneath it this morning and took a quick look and yes the driveshaft is definately disconnected and it also took out a fuel line and my neutral safety switch. ill get a better look at it this week and im sure ill be posting some questions on fixing it. stay tuned
