Hi everyone, I decided to make a writeup/instructions for how to install the hidden winch system I designed to be used with a slightly modified stock bumper.
Files can be purchased here. I don't check here all the time so I may be delayed if you comment or message. DIY offroad will be a download so you wont have to wait for me.
Side Note: If you live in a rust prone area, start soaking your stock bumper mounting hardware ASAP.
Step One:
Fully weld the upper brackets together. You need a mirrored pair of brackets.
The upper mounts can be fully welded on all seams. The lower plate needs to be flipped on one bracket before welding as seen in the images.
Step Two:
Weld the lower brackets. Once again you need a mirrored pair of brackets. Match them to the images.
Step Three:
You will need to grind smooth the mounting face that on the upper brackets that mount to the stock bumper brackets along with the face that mounts to the winch plate. See later install steps to see which faces those are.
On the lower brackets you will need to grind smooth the faces that mount to the winch plate and the stock bumper shell.
Step Four:
While all the welds are cooling, remove the stock bumper.
This one should be pretty straightforward. You will need to remove four nuts by laying underneath the truck. They should be 19mm or 3/4" sized wrench/socket.
Step Five:
Remove stock bumper brackets from the stock bumper. This is a 10mm wrench/socket. These brackets can be discarded or stored as they are not longer used.
Keep the stock mounting bolts and leave the nut clips on the bumper as these will be reused. If you source replacements then discard.
Step Six:
Modify the harbor freight winch bumper to prevent interference with frame or stock bumper shell. I cut 4" off of the front and rear flanges. I also cut an approximate 45 degree cut 2" long on the front outer corners.
Grind some paint off where the fairlead nuts mount on the winch plate then mount the fairlead. Using the welder, heavily tack weld the nuts to the back of the winch plate. Then remove the fairlead.
Step Seven:
Mount the upper and lower brackets to the harbor freight winch mount. I used hardware from McMaster. I installed all bolts with the nuts on top. This isn't super critical which direction they face. It may be easier to tighten them later on if they have the nuts on the bottom. I preferred them on top to prevent snags while off-roading.
You can fully torque the two bolts in front that are closer together. Leave the rear two bolts finger tight as this is how you adjust the sag on the ends of the bumper that wrap around the fenders.
