I started to put my front end back together with all new bushings and what not. After reading the manual, (forgot how it went back together) it mentions to use a special tool to install the upper control arm shafts and bushing. Is this tool necessary? or can I get by with turning each bushing an equal number of times to make sure there centered.

Here's what the tool looks like:

Thanks in advance for your help.
