knocking/bearing sound output shaft bearing?

[rysermon]

hey guys,

i have noticed a strange quiet knocking sound like a bearing when its on its way out at slow speeds, the other morning on the way to work when it was cold i noticed it around 80km/h and as i slowed down it was squeaking also.. theres no movement or obviousness to the front left hub bearing being shot, i have been tossing up if its a bearing or a cv joint... my cars done 39000kms on original cv's and bearings, the cv boots are mint condition also.

i thought it was either a hub bearing or cv Until!
i jacked up the front end and noticed when i spun either wheel as the front driveshaft/prop shaft turned where it meets the transfer case it was making the exact noise i can hear at low speeds, correct me if i am wrong i believe this is a output shaft bearing?

so im not sure if its this and also a wheel bearing or if its all entirely this. i know it shouldnt make noise as i have spun it before in the air and not heard anything

can anyone shed light on this i know its a doosey but the internets letting me down lol

well if anyones interested, after using an entire tube of grease filling up the uni joint and front slip yoke it seems to have shut up a significant amount... mates giving it one more check over and drive tomorrow to see if it spikes up again if not then il just drive it and see if it comes back or not.

Should never over load UNi with grease , though sounds like it was dry ?!

prop shaft was the one that took alot of it. but seems like its fixed it... see how it goes it drove okay today
