I did mine on the floor of my garage when I did my suspension refresh. It wasn't too hard. ONCE I got the proper bushing removal tool. Those "universal" tools do not work on our X5's. You have to have a flat side or it won't fit. With the correct tool, it's a snap.

I was in a jam time wise and had to buy this one. Cost is ridiculous, but I'll probably sell it when I someday let go of my X5. If I don't buy another. https://www.ebay.com/itm/For-2006-20...EAAOSwZ7VddDYc

The tool you need is also available super cheap on Ebay. If you don't plan on using it more than once or twice, they're probably OK.
