a few months ago i had a axle click on the right side and i took it to a shop and all they did was used a impact to tighten the nut a lil bit. after that it didnt click, now every time i start from a stop or go backwards it pops on the right side. when i go forward from a stop i also get a shake on the right side too. any ideas?

 

simply tightening those nuts isn't enough.. you need to remove, apply new grease, and re-torque to the new spec. The grease is important to prevent noise.
