    something wierd is going on with my 99 K2500 sometimes when i make a really sharp turn or when i am pulling into my driveway i can hear a clunk coming from the front left of the truck. i crawled under there and i noticed there is a slight ammount of grease leaking out from the boot on the CV shaft. this just started doing this. i am thinking it has something to do with the abuse the truck has been taking this hunting season as the hunting trails have ruts like you wouldnt believe and it shakes the truck all over the place. if anybody knows what the problem might be i would really like to know.

    thanks for the help guys

    Does it do it the whole way through the turn? Like a "clunk" "clunk" "clunk"? Or does it only do it one time when you turn the wheel sharply?

    it only does it if i turn sharply or turn and hit a bump at the same time. i noticed it for the first time today turning really tight in a parking lot. and then when i got home pulling into the driveway. but ya it clunks 2 or 3 times. but it doesnt always do it. id imagine it would get worse over time.

    Check your swaybar end links. Just had to change mine, one was broken. Took me forever to figure out where the noise was coming from, most of the bolt was still there so it didn't look obviously broken, but it could slap up and down when I hit a bump.
    Might be unrelated to the boot issue. Course if it were the swaybar end link I think it would do it even if you aren't turning.

    Hey, I just noticed I hit 1,000 posts! Yay me!

    Yea it could be a CV shaft but I think I'd dig around a little more before just replacing it.... check over the steering too. Check the tie rods, pitman arm, and especially the idler arm. They will give you the same kind of clunk in a turn too. Also, check the calipers and brake pads to make sure they're tight on the spindle.

    Check your torsion bar mounts also. I have a similar noise coming from my typhoon, on sharp turns, off camber turns and bumps, and the torsion bar mounts are the issue. IDK if the full size trucks could possibly have the same setup. Just a thought

    That definitely can be a problem on the mid-sized trucks but doesn't apply on the full size's, as they do in fact use a different TB arrangement.. The mid size's use a rubber mount/isolator setup on the TB cross-member...the full-size's don't. But a good tip for the mid size truck owners non the less jbone..
