yeah, you can test 'em, first start by seeing ig their is any play in the u-joints by hand... if yes well then problem solved. If not, try a small pry bar to see if there is any play. also, you could put the truck up on stands and turn the wheel by hand and see if you can hear exactly where the noise is coming from. If you need help, I see you are in Ringwood, I am in Hopatcong... not too far. I will be working on mine Saturday afternoon (new front springs). email me for a phone number and I will see if I can help.
