Going in next week to get a one piece as the shudders have drove me mad.

Just need to know if there is anything I need to do before or after I take it in or if the shop will do all the work. Is it just as simple as them removing the carrier bearing and putting in a new shaft?

Thanks!

P.S.
I'm aware of the search function, but after 45 minutes of searching and not finding a definate answer, I gave up. Sorry.
