I had to replace both of my 1-Ton front end's (installed by Jim Hupy just before I bought the coach) outer boots - I think it was a combination of the early hex head bolts (later versions had smooth carriage bolts?) and soft CV boot material (later ones were more "firm"?). They were both torn with relatively few miles. Not a horrible job replacing them on a 1-Ton - but it seemed like the getting the angles just right was key to the process. Dave Jarvis helped with the first one - and I did the other one the following season.
I left the hex head bolts installed and used some different boots that came from Manny. I may have carriage bolts from Manny as well - but figured "why mess with it?", if things are OK with the new boots. I've got many thousands of miles on the second set of boots.
I also had to replace both front flex hoses - due to interference issues with the front axle shaft (RHS) and control arm (LHS). The first failure was dangerously close to converting me to becoming religious...
Just looked it up - 1-Ton was installed in the first half of 2012! I think the later versions used the different parts.
