noise under truck

[craneman03]

I have started to notice that when i turn over an uneven surface in a parking lot or driveway or the road, there seems to be rubbing or thumping that seems to be hitting the floor under the cab. Its really hard to pinpoint sometimes. I know the front end is all okay I just had it worked on recently. Think there could be a mount coming loose or going bad? Any ideas would be helpful.

Could your tire be rubbing the back of the finder next to the door? If the suspension is compressed when you turn it could be that. I got a friend with a 6.0 with a little lift and somebody put the bolts threads towards the tire and it rubs when he turns sharp. Hope it helps.
