Removed the grates, drip pans, and trap. Removed the old flavorizer bars and dials. Removed the two manifold cover screws, removed the cover. Removed the manifold bolt, and pulled the manifold away. Removed the old burner tubes. Cleaned the drip areas, installed new burner tubes, reinstalled manifold, manifold cover, dials, installed new flavorizer bars, reinstalled grates.
Tested burners. Worked like new.
Placed one side of grill on milk crate, pulled old casters, reinstalled new, and repeated process for other side.

Removed the doors and front cover of my Weber Summit Grill. (The means and fashion for doing so can be found on the internet and on youtube. I replaced the 5 of my 8 burner tubes plus the searing station burner, also replaced the light switch which had melted in our Phoenix Az heat and replaced one of the magnet in the doors. Project took about an hour and a half and the grill now works like new. Very please with eReplacementParts.com I received what I ordered in a timely fashion and the instructions included with the material were very good and detailed.

Removed all hardware in cook box, installed new cook box a and all parts inside.
A few problems but we worked them out

Only issue was wound up with 2 extra sets of flavor bar holders. The flavor bar holders were part of the cook box

Also the LED sensor for the propane tank , and the control knob lights were not working. I ordered multiple Weber parts because I wasn't sure exactly what was wrong. Each part came with its own replacement instructions from Weber. Instructions were great. I had to remove the knobs and the front control panel to replace the burner tubes, wiring harness and LED sensor. It was all pretty easy with the detailed instructions with lots of pictures from Weber. I also replaced the battery pack housing. I spent about $200, but I pretty much have a brand new BBQ. I suspect it will be another 5+ years before I need to do any more work on this BBQ.

Door magnets take some force to remove, make sure you work one side first and then the other. Take a look at the new magnet to see which side comes out first. Handle is a breeze, takes about 2 mins. to replace. Burner is a little more time consuming since your have to disassemble the grill a little.
