I did it with my e46 ,released the outer tie rod end so I can swing the entire hub away, but in my case as, i did it the same way i did it in my E53 by unclamping the inner boot and thereby releasing the tripod from the inner hub? then unclamped the outer CV boot, gave the tripod a good whack with a crowbar and the outer CV joint came off from the outer hub.Cleaned inserted big inner clamp ,inner boot, inner boot clamp then outer clamp, outer boot ,outer clamp thru the outer "free" end .Installed free end into outer hub ,packed with grease,burped and tightened clamps.Then packed inner hub with grease installed adapter ,then the tripod,into inner hub,pushed inner boot to over inner hub,burped,clamped and tightened. Installed the outer tie rod end tightened to spec...so there all this without taking the entire outer cv joint out of the wheel assembly,and without taking the tripod off the axle rod? itself.
Some folks have done it differently but this works for me,...took me an hour taking my time compared to the whole afternoon that it took when i did both inner and outer boots both passenger and driver side for the E53, it was my first time.
