Vibration on driveshaft after new u-joint and carrier bearing

Guys, little advice here.... those with knowledge on driveshaft... I've been having issues with the Toyota dealer shop were I take the truck for maintenance... latest scheduled service I reported a squeaky noise under the Tacoma and they suggested it was time to chance u-joints on the rear driveshaft and carrier bearing, since they did the change I've been returning the truck as they generated a vibration it was not present before. The vibration is present at 13mph and more noticeable from 62 to 75mph, mall vibration worth to mention but... it wasn't there before. The truck is completely stock TRD sport 4x4 2013,

And well, the dealer has no clue on what is wrong, my theory is that they did not assembly back the drive shaft in the right order and respecting the splines on each components as they only worked in this part of the truck.

So, today I checked angles on the driveshaft and, I think this is the responsible of the vibrations but I would like to hear your opinions about it... What do you think on the difference in degrees, seems they are not exactly on the same phase.

I would appreciate any comment... Tnx

 

They need to balance the shaft


Looks like a CB drop may help you too
