So, I had this annoying vibration at 70 km to 80 km I couldn't even look up my side mirror cuz it moves so much.



So I stupidly put my truck in park and went under it to check U joints for movements haha.



After I smartened up I've chocked my wheel and put it in neutral and then retry it.



The thing is I remembered when we put my Motor in at Roy's shop, I was a nut that dropped my front shaft and my U-joint cups fell out.

Roy replace that U-joint oh, and there I go again and make the other side fall out while trying to install the shaft, so Roy replace that as well.

In my head my U-joints were great but I forgot to realize that there are three U-joints in the front.



I wiggled the middle U joint and there was movement and this is what I saw after I removed it.

The one cup was totally dust and no grease was able to get in there

This is some pictures of me taking it apart.

Lol, as soon as I removed my ujoint FedEx showed with my part...

Then putting her back together

Ps. Lol a 3/4 socket had to die during my quest...all mangled...hehe



Now shes smooooooth at all speeds .

I was expecting the front driveshaft to be a real pain to get out but I found the secret was to collapse the slip yolks and push it back andit will just fall past the sway bar and pull out



Lol, just to be safe I added more grease in each cup to make sure its extra lubed

I maybe have the same issue with my truck. I will have to check those joints as i believe they have never been replaced as of yet. 

So the moral of this is... do all universals at one time.
