[Lerocious]

Hi I live in el Reno okla. I recently have purchased a max iv off a good friend of mine, it was sitting in his yard for some time getting rained in and rusted to hell I kept on bugging him to sell it to me and finally he did $1000 bux o yea I was happy to get my new toy I'm curious as to what year my max iv is.because they pretty much all look the same. I got it running great and took it out to the south Canadian River a couple times and I had my cousin take it back to his house where I was gonna mount the winch bracket on it I get out there to work on it and the back left axle has been broke in half and chains were just layin in a bind errrrr I was a mad mofo someone had taken it off the trailer and pretty much dumped it on the spot and broke the axle so cousin gonna pay for it and what ever else got broke .but my question would be is the max II set upretty much the same as maxiv And do I have to pull motor to replace left rear axle
