Comp housing is a big circlip and then housing will come off the cartridge, you will have to remove the small pin from the housing when you refit. Its just pushed in so grab and yank it out. Exhaust housing will probably need a hammer and chisel in the gay once the clip is removed to seperate the two halfs. Then clean both and put some copper grease on there. You can clock it roughly on the bench but chances are unless you have done one before it will need redoing when you actually bolt it to the car.
Doesnt even own a 306.
