Nope they are covering it under warranty. The mechanic recommended it and said the whole driveshaft should be linear . He said when it’s sitting still it’s fine but when in motion it might have to much up and down movement for the bearing . He also said this may be a preventative thing to prevent it from happening again .Do you remember what brand you have ?
No i dont but it looked normal to me . He said the downward movement may have caused it. He also said there is no way of telling 100 percent what caused this to happen and may just be a parts failure. The tech said after the warranty is off i may want to look into a one piece driveshaft.
When i got mine that rock jock was the only one available so it made that choice very easy haha i also watched a handful of videos that talked about drive shaft angles and, as far as i understood them, a straight line from the tcase to the dif was not the optimal angle.
Yep, The rock jock is 3/4. I guess if everything moves equally adding 2in of spring lift raises the body by 2in. Which means the drive shaft could hypothetically be lowered by 2in and be back to a “factory” alignment. ?
with that in mind I don’t think its that exact and i dont THINK its a big issue since the shaft angle changes during vehicle operation and is only a problem when put at more extreme angles.
sounds about right i guessYep, The rock jock is 3/4. I guess if everything moves equally adding 2in of spring lift raises the body by 2in. Which means the drive shaft could hypothetically be lowered by 2in and be back to a “factory” alignment. ?
as an example my jku had 4in of spring/spacer lift with an additional 1in body spacer lift. So I definitely put that one at just enough of an angle that after 50-60k miles my shafts needed attention.
