4x4 Build Ep.1 - BMW E39 Differentials & Axles

Introduction to a new fabrication and metal working series - a four wheel drive utility vehicle build to lessen the work load on my trusty 2002 Honda Foreman Rubicon TRX500FA. This partially answers the question "Why?" but for those who want to ask "why don't you just buy a side-by-side instead of building one?" I just want to say - I'm not made of money. Side by sides are ridiculously expensive, even the car I drive around daily is worth less (not worthless though!), hell, it is even worth less than my 2002 Honda ATV.

"How much HP will it have?" - the 1.4 litre FWD petrol engine I'm planning on using has 55 kw and this will not change, but the torque will be quadrupled via the FWD differential I'm using to transfer power to front and rear diff.

"It will be too heavy!" - this project just like the firewood processor project does not have to float. And a heavier vehicle will handle better anyway when hauling heavy loads.

In this first video I'm disassembling two BMW E39 independent rear suspensions to get the differential and half axles out, scraping together parts I have laying around and looking for an engine donor. Stay tuned for future episodes! Thanks for watching!
