I've replaced mine on my mtx, but not on my atx, but the procedure should be similar. Basically, all you do is unbolt the old one, and bolt the new one back in. You can use a jack with a block of wood on top to slightly lift the engine/tranny and take some of the weight off of the mount. There have been a lot of posts in the past talking about the detailed procedures, but it's really a fairly straightforward procedure. At least, on the mtx's.
