Well, I appologize if that upsets you, ( I read that term on the TDR from another post and it made me laugh ) but that is what I feel has happend.
I took my truck in to the dealership in April for a TM yoke leak ( ATF ) and a vibration, they took my deductible and it took them this long to get the replacement part and replace the front yoke ( they re-used the U Joint! as they said is was not bad enought to replace. ) I took the truck out and it still vibrates, and shakes ( clutch in / out no difference ) the answer I received is that ALL long wheel base trucks do this and there is nothing they can / will do. I asked if they checked the balance on the shaft... ... ..... No, woudl they... ... ... ... . No, So for what I have paid them... ... ... I could have taken the shaft to a Driveline specialist and had all the joints replaced and the final assy. balanced, so in short... .
I feel as I have been stolen from and taken for a ride.
This tech and service manager also said the the vibration willl have no ill effects to the axle or transfer case if I continue to operate it in this condition... ... . and we all know how that ends.
Once again, I appolgize if you are offended, I just want to move on and repair my truck so I can use it.
