Pop noise when weight transfers ?

My suspension has never made any noise out of the ordinary untill i loaded my truck up with a bunch of stuff for a two week road trip . It was the first time its been loaded since i cranked t bars and added the shackle. sometimes it does it when i take off and sometimes its when i brake , lately its when i brake but before it did it taking off . It was pretty loud when it was loaded on vacation and i thought it was from the back end. i been driving for a month unloaded and it still makes the noise but not as loud now. i think it might be the front now but its hard to tell . I tried jumping on the bumper but no noise . it doesn't make the noise on bumps just the first moment of hard accelration or breaking.

maybe the ball joints ? 34,000 miles and a few thousand miles in 4 low flexin.

it sounds sort of like when u crank the wheel all the way and flex.

Im having the same problem. it happens when taking off and when i cut the wheel to the left. it soulds like metal on metal kinda like a knocking sound. i havent had time to pull off the wheel to check the pads or rotor but i checked all the ball joints, bushings, tie rods, sway bar and mounts and everything looks fine. my truck jus rolled passed 57,000miles. any suggestions?

I'm having the same thing, and I tend to notice it ALL THE TIME in 4wheel drive, and occasionally in 2wd (especially when cold). If in 4wd, and making a sudden stop on a snowy trail, it does it the worst (abs kicks on).

*I think* for me its the front drive shaft finally biting the dust since I'm lifted, though I can't nail it down for sure. I thought it was a ball joint at first too, but can't nail it down.

I thought it was a possible effect from snapping the driverside half shaft, but doubt it.


It feels and sounds like its coming from right under the driver floor board, which again leads me to believe its the drive shaft.


02rangermayhem, are you a 4X4 as well with cranked Tbars?

I'm noticing something similar as well with my '07 4x4 (stock suspension).
I get a kind of clunking sound when coming to a stop or accelerating with the wheels turned. It is worse in tight turns, like in a parking lot for example.

D94R - I never put it in 4x4 when it was happening (and i cant test it now cause i already fixed it) and i also never cranked my t-bars.

brightred - I am pretty sure u have the same thing wrong with your truck as mine did. exact same symptoms.

The way you could test to see if it is a bad wheel bearing is to jack up the front of your truck (be sure to use a jack stand cause you will have to grab the bottom of your tire. you dont want to crush your hand if the jack gives out.) Grab the top and bottom of your tire and try to push and pull on the tire. There should be no play. if there is, then it very well could be a wheel bearing or hub nut that is not tightened to specs. Too make sure its not a tie rod have a fiend (who knows what their doing) and have them look at the knuckle. if the whole knuckle moves it could be a tie rod. if the axle shaft moves then its the bearing or hub nut. I know on my 02' you cant buy just the bearing and you have to buy the whole hub assembly. which sucks cause its $200. hope this will help.

P.S. - On my truck it turned out to be a bad wheel bearing and the cause was the hub nut was not properly tightened.

I have about 8500 miles on it, so I'm a little concerned that I'm having this problem already.... (I'm still under warranty so I'm going to try and take it to the dealer next week, I just haven't had time yet)

02ranger - thanks for the info, I may try that this weekend just to see.

Hrrm, hub sounds like a more plausible suggestion. I'll have to retorque mine and see if that *helps* it if it isn't beyond fixing. Luckily I still have my stock hubs that I can swap to the Superlift knuckles if need be.

d94r - i think it sound more fitting that it would be the hub nut. a 2007 should not be having a wheel bearing go bad this soon. i would recommend u take care of it asap or park the truck till u can. if it is loose and u hit a pot hole or bump u could break ur wheel bearing, and or in worse case the wheel could essentially come off. lol.
