Roaring in front end of 2004 kia sedona. could be CV joint or bearing ?

Roar can often be associated with failing wheel bearings, but they usually don't cause severe vibration, maybe a little bit when turning. Vibration in the drive train is most often associated with struts and/or CV shafts/joints going bad. If you are sure the struts and strut mounts are good, then I'd have the CV joints looked at.

Hi Phil, On the Spyder end of the shaft that fits into the gearbox there is a retaining clip. Did you knock it in securely? If you did then a seal may have become damaged when making the replacement. That will need replacement. Regards John

Yes, a CV joint problem can cause a popping noise in the front end (usually worse when turning).

Two likely problems.

CV Joint, or Wheel Bearing... constant "roaring" that does not change under power, breaking or turning is likely a Bearing, worse when turning or accelerating, CV Joint. Both fun to fix...!

Peace,

My guess is the original shim that came with the factory bearing and hub assembly was discarded and never installed on the new bearing (That does not come with a shim) causing the new bearing to fail.

you could have more than one problem the vibration accelrating maybe an inner cv joint ,if you just had the tires replace and an aligment done they should have checked the front end for worn out ball joint and tierods but the wheel bearing may not have any movment but can still make noise

Several items can contribute to the shaking of the front end. Bad tires, any slack in the hubs, a bad CV joint, worn tie rods, ball joints. I would first check out the tires and then proceed to searching for components that have worn and have slack in them. Replace as necessary.

one check if your wheels are tight 95 ftlbs if mag wheels remove make sure no heavy corrosin arond hub and rim wheel will not seat properly and come loose. 2 check front end if belts are showing check ball joints and tie rides for wear vans are also known
for bad wheel bearings even if you cant hear it at 80km50mph give or take it may have ecssive play
check that front end .otherchecks ps pump and or loose p/s belt

Sounds like your wheel bearing is going if no other noises present when braking

I have the same van there was a factory recall to repair the bearings in the front tires. If taken in to a kia dealer this problem will be repaired for free.
