i removed the harmonic wheel on front diff and vibration is much worse

we drove onto a lift and jacked up by the axles , vibration is not the driveshaft, it is coming from the hubs, vibrating the track bar and steering wheel, i tried rotate and balance tires no change, so i dont know if its the 3rd, or cv going bad or ????

i have changed wheel bearings and races and rotors , back in fall, serviced the rears last week and there is oo in the cv housings

tires on the front were chopped on inside and outside

ideas?

 

Tires sound like a real problem. Air pressure was wrong? Does it increase w speed? Or decrease? Rattle the steering wheel or your butt?

 

starts around 35? mph sort of becomes less noticiable at faster speeds, i have ruled out tires as i had this jacked off the ground and balanced tires and still was doing it on the lift, ie there was no rolling resistance on the tires

i am sure i need to adjust the castor since i can look at the diff and see the pinion pitched up from the lift

when we had it on the lift i could put my hand on the axle housing with no real vibration there, only the track bar and drag link were vibrating

now i did the wheel bearings, is there another bearing near the swivel housing that could be going bad or should i expect cv failure soon? i am not hearing any odd noises like in a front wheel drive with failing cv

 

I'd check the front bearings again, make sure they're toight!!!

 

I seated them pretty good but guess its worth a shot

 

CV impending failure usually has a different vibration or noise depending on their angle. Does it change turning right or left?
There's a bearing in the stub axle.

 

yeah there is no noise with this, i know a car cv going knocks when turning, guessing these do similar, i did not do the stub bearings iirc

this vibration seems more under power then coasting

i have the long drive home to n.j. this afternoon so i will try to pay more attention to characteristics

definitly seems worse starting 30-35 mph to 45ish ? while accelerating thin fades back out to slight vibration as i go faster

this is why we ran it on the lift, wheels up, to be sure it was not a drive shaft or transfercase issue

stub bearings in the housing? like i pull the axle and swivel ball and its in there with a seal right?

 

yeah, behind the seal. Roller bearing.

 

i see why i did not do them at least on the front, requires breaking down the swivel and removing axle and cv from swivel housing?

 

Yep. I do em w bearing replacement.
