Could be steering related. there is a pop that i can feel in the floor boards when i turn the steering wheel. its when the wheel is turned right for the most part. gets worse on inclines so turning going over hills or unlevel road. cant find the source of the problem. dont believe its cv related-mine do not rotate unless locked in and i have no additional issues when they are locked in. ive replaced balljoints, outter tie rod, upper control arm, and sway bar links last year. they are moog and greasables.
havent replaced rack bushings, inner tie rods, someone suggested that it might be the kevlar padding that is above the torsion bar adjuster key.

any ideas? its rather annoying

 

maybe a hub?

 

The driver side is still stock. Could that be a symptom.
A new symptom tonight and previously noticed but seems to come and go is wheel.shimmy over bumps.

 

Thats what mine did and it was my drivers side hub.. id have it checked out..

 

Hub or cv joint? Are your bars cranked?

 

Ya t bars cranked.
Are we talkin the manual locking hub or the hub and bearing assembly? I didnt think a hub could produce those symptoms.

 

The assembly.

I'm beginning to have the same symptoms. New hubs here I come.

 

The hub and bearings itself. I think my right one is starting to go..

 

The hub assembly would make that pop? Interesting
I broughy it in the shop today and guy here thinks the fluid is aireborne and still has air bubbles caught in the steering system. But that wouldnt explain the pop.
prob need a new rack but were leaning towards the upper control arm mounts. Mayb not tightened down good?

 

Sounds like a hub. my truck eats them like Taylor eats oysters.

hubs can click, grind, screech to hell, pop, clunk, and the worse wheel falls off and i'm sure you can make that noise up yourself. I would double check you end links they do get loose. and for **** check your caliper bolts

 

thats a good idea about the caliper bolts! tie rod end feels tight and ball joints torqued correctly greased and feel tight.
i was just yanking on the cv axles and the driver side spins and has little play side to side as well as in and out. the passenger side has in and out play, doesnt move side to side but also spins. not sure how to check those.
im gunna see how my caliper bolts are now. i wouldnt doubt the hub cuz its stock but ima leave that for worst case scenario-there does seem to be some humming-more higher pitched but its very faint and im not sure if its just my mind playing games.

edit-caliper bolts check out.
