Mutt Evolution

Post by GARETT0439 » December 11th, 2011, 2:36 pm

My dads had a mutt since he was in highschool(stock a1) However, the stock mutt didn't meet his offroad needs. Here are some pictures of the mutt that evolved from Johnson Valley's Hammer trails back in the early to mid 90's.

Top Truck Challenge 1995 4th place finish overall (next tire size up from his mutt was 35, he had 32's. And he was running open diff at the time. That's where he discovered the suzuki samurai locker fits in the mutt diff.)

100$ Bet against a hummer H1 owner(first h1 over the rubicon) that he could twist the rock... he rolled the first time, 2nd attempt was successful. The bet was called off, good times... he says "no alcohol involved"

Do you still have the info on the Suzuki locker? I lost that procedure years ago and always wanted to try it.

That was the link I was talking about but do you have the spewcifics for the modifications? How much to machine off the side gears and where are you getting the replacement axles? Ron had some really neat stuff but he dropped off the face of the earth so none of the stuff can be duplicated.

I don't think there's an exact amount of metal to grind off, its kind of just a grind&check. I just ground a little, then secured it in a vice and turned the yokes while peeking in to see if the locking mechanism had enough room on each side to expand. I used a new brand of locker(spartan lockright) which has teeth that are shaped a little bit different from the older traditional lockrights, so I had to round the teeth of my yokes in order to get it to disengage.

All I have done to strengthen my front drivetrain so far is put spicer ujoints on the outsides, where the gnarly angles occur.

It mentions in the post a modified spider, what is the modification? And do those axles come with the kit and work without modification?

I don't know what they are talking about with that kit. I got the spartan locker and i didn't have to jack around with aftermarket axles, all we did was round the teeth of the axles shafts in order for the locker to disengage more freely when in 2wd.

Which Spicer U-Joints did you use? Was there any modifications necessary?
