2007 h3 clicking noise front drive shaft.

Here is the video of my 2007, any ideas of what this noise might be? Thanks.

Your front differential is likely worn out and needs to be rebuilt.

Remove the drive shaft from the front diff and check for the noise again. Will determine if it is the front diff or not. What condition is the drive shaft CV joint? Could be it is toast. Drain the front diff fluid and look for metal shavings and chunks, take the cover off and inspect. Drain the TC and look for the same.

I have had this happen to me before

First thing to check is that CV on the Diff side of the drive front shaft.

This is the way I do it:
If you have a rubber mallet you do not have to un-bolt anything to check. Park your H3 on level ground, lay down within reach of the drive shaft and give it a tap. If you hear it move and make an obvious clank sound, you need to replace the CV (easy job to do yourself). If the rubber boot is ripped, you need a new CV joint. Now if the drive shaft sounds solid when you give it a tap (you will know if it sounds solid) then it is time to move onto your diff as suggested previously

Thanks for your reply! I have changed both front CV shafts along with wheel hubs. I did drain the Front diff fluid and found it clean, I am now taking off the drive shaft to inspect. In the video it is very visible the "movement" of the bolt holding the diff to the cross member so I ordered new polyurethane bushing.
