What is your process for checking over suspension/steering parts? I usually try wiggling wheels top/bottom and left/right with vehicle on ground, bounce the shocks/struts, lift the vehicle, wiggle again with wheels pointed left,right and straight, grab sway links and check for play, visually inspect tie rod ends, ball joints, bushings, etc. Usually check strut bearing by grabbing wheel and steering it back and forth. Wheel bearings checked by rotating wheels and listening/feeling for vibration/grumble. Most times I can pinpoint suspension noises, but now and then i find it hard to nail down a clunk or rattle. Seems like if the noise is in a strut or in a bushing (for instance; a control arm bushing) its hard to get it to make noise unless its being driven. Any tricks that you use or anything im missing?

Check out a company called TigerTool. They make some awesome suspension and driveline tools and if you do a lot of work in that category they pay for themselves. Love the u-joint tool set and the outer tie rod sockets. They are spendy but really well built.
