Gen 3.5 DIY Skid plate build

So about two weeks ago I was driving to work before sunrise. It was dark and a few cars on the road. As I rounded a turn and came over a rise in the road there was a cone tipped over away from me in the center of the lane. I was going about 50. I wasn't sure if there was a car next to me or behind me so I didn't want to swerve or slam on my brakes. So I basically hit the cone straight on and in the middle. As I drove I heard a scraping/grinding sound as I went faster. Took it to the. Dealer and found out my 4-wheel-drive-actuator had been partly crunched. Had that replaced for $528.31 for parts and labor. Needless to say I was pissed. I knew I wanted skid plates before this even happened. Now I was on a mission.
I prefer to do everything for a cheap as possible. I know I could have done a junkyard swap for the 4wd actuator but I was not completely certain that was the only problem and I like to do things correctly more than I do cheaply.
So off to Home Depot to get the following: 2, 10mm -1.25x 30 (17mm socket) bolts for the two forward mounting tabs for the original plastic skid plate, then 2, 8mm -1.25x20 (13mm socket) bolts for the rear mounting tabs on the center cross member, then a piece me metal 2"x36"x .125" (1/8th). I had alread acquired a piece of sheet metal aluminum (similar to a street sign) 18" wide x about 18" long.
I drilled holes on the steel after I cut it down to 20" long so it could reach the mounting tabs on the center cross member. This would act as a stiffener as well as a bridge for the width of the mounting tabs since my sheet metal was a little too narrow for that. I then drilled 4 holes in the steel "bridge" and the end of the new skid plate and bolted it all together (used 4, 1/4" bolts with loctite) not super tight to allow for some natural flex. The skid plate I used was run over or something and had a nice curve on it that actually worked pretty good to reach the forward and center cross member mounting tabs and kind of naturally curved over the 4wd actuator and front diff.
After mounting the skid plate at the rear I measured (and guessed a little after looking for about where the holes would need to be for the forward mounting tabs.) Then drilled and had to Dremel the hols a bit to allow easy insertion for the 4 bolts.image.jpg 4wd actuator that was broken and replaced. Here is the new one shown.

Posted this from my iPhone so it is not as great as I wanted it. I will be happy to answer questions and I have a few more pics.

Maybe its just me, but i think steel would've been more ideal for this item. You can bet on the aluminum to just get bent up with the next hit.

I should also point out that I am only expecting minimum to moderate protection. Should be good enough for a cone or branches. Not looking for protection from rocks and such. That would be nice but I don't have money for much more than I have here.

Good job working with what you have available! Look at it like this...you have a template made if you ever decide to upgrade materials. Cheers.

Yes, thank you on the template idea. That is what I was thinking. I failed to mention that my out of pocket cost was $17.00. Which I think is pretty good for being able to prevent another $528.31 bill for the 4wd actuator. I might also add another layer of sheet metal onto the existing home made skid plate to add strength and widen coverage. Not a perfect skid plate but better than plastic and better than not having one.

Good idea. I have another large piece of aluminum so if it will fit I will put it there. MPGs are not great but I do love my Monty!

Did an oil change this weekend on the gen 3, the 4wd actuator sits really low and has virtually no protection in front of it. I'll have to look into doing something similar

I can post other pics or give some measurements beyond what is already there if it helps.
I got a larger sheet of aluminum so I might make a bigger one or add another layer.
Benner Metal in Fullerton, CA has 1/4" aluminum for $195.00 for a 4x8 foot sheet if I decide to go big and spend some money...
