Lego Star Wars Skywalker Saga Hunk Of Junk Minikits are collectibles you can obtain in a relatively small area, more precisely in the hangar where you have to get the Millennium Falcon up and running.
It is worth mentioning that you can’t get all the Minikits in your first run of the mission, and you will have to come back in Free Play.
If the mission Hunk Of Junk takes place in a smaller area, it doesn’t necessarily mean that the collectibles are easier to obtain, so you might want to check the guide below if you get stuck with any of them.
Minikit #1: Between The Two Boxes
After you start the mission, kill the stormtroopers and start exploring.
The first Hunk Of Junk Minikit is located behind a door on the north side of the hangar, in the alcove to the right of the elevator.
To open the door, you must first break the boxes on the left to reveal a console that you can only use with a Hero character.
Once you get the door opened, pull the two boxes to their sockets, and you will reveal the Hunk Of Junk Minikit #1 like in the following image.
Grab it and continue the exploration.
Minikit #2: Near The Socket
You can find the following collectible in the northeast of the hangar, in the next alcove to the right of the previous Minikit.
To open this door, you will need a Villain character. You can unlock some Villains later in Episode IV.
After you use the console and open the door, you will have to locate one of those brown bricks with legs.
Then bring the mount here and put it in the socket to reveal the second Lego Star Wars Skywalker Saga Hunk Of Junk Minikit.
Minikit #3: On The Wall
The third collectible is in the alcove on the southwest side of the hangar, right there above the two X’s on the wall like in the next screenshot.
Here you should normally use a Scavenger character to get to the Minikit, but you can also use a Jedi like Old Ben Kenobi.
All you have to do with the Jedi character is to rearrange some boxes in the alcove with the help of the force so you can make the jump to the collectible.
Any way you choose will get you the Hunk Of Junk Minikit #3.
Minikit #4: Right From The Elevator
You will have to continue with the mission’s objectives until you reach the upper level for the next collectible.
Once you are there, turn right from the elevator and enter the first room you can spot.
As you can see in the following image, you should find some boxes in the room.
Break them and rebuild the remaining pieces in the fourth Lego Star Wars Skywalker Saga Hunk Of Junk Minikit.
Minikit #5: On The Left In The Room
To obtain the last collectible, you will have to continue with the current objective and lower the sensor dish in place.
This will make more stormtroopers appear in the hangar and open all the doors on the upper level.
You will have to enter the room on the opposite side of the elevator, right in front of the overhead crane.
On the left, inside the room, you will find the culprit.
