Doing a good bit of stuff on my buddies 250k miles 2011 1500 Chevy Z71 this weekend. Ball joints, front and rear shocks, sway bar links, coolant, oil change, along with a new belt and idler pulley and belt tensioner. It'll be no problem for us to do all of this, we have access to a lift and all the proper tools. The only problem is both motor mounts are bad and we'd like to change them, we've never changed motor mounts before. I've looked up videos on youtube but none explain very well. Has anyone done this and knows any tips or tricks? This truck is used for his grass cutting business and hauls 5,000 pounds daily, so it needs to be back on the road asap.
