I know a number of people that have had it done at the axle shop, I plan on doing it in my drive way. I have no idea what it would cost to have done at a shop but at $45 an axle and some basic mechanical know how (youtube videos) its worth a shot. I think the tricky part is going to be getting the TT up high enough and blocked up safely to do the work. Most of the time I just kinda go at it and figure it out on the way but I have put alot of thought into this one. We had plans to do it at a friends place but it dawned on me that if for some reason we couldn't get it done it would have to sit there so I moved location. I plan on doing a wright up and posting that with some pic's. Probably get going on it mid-late march.
