Meritor RF611/ford 9" axle build
What would pirate build? Which center section (9", sterling 10.25, dana 70, 14 bolt, etc) would you use to build these axles (matching front & rear steering)?
The axles are the Meritor RF 611 planetary, I choose these because its a 2:1 reduction at the hub, there is a local supplier that I can drive to, parts are plentiful and the axles are cheap. What I will use is everything from the inner C out & the inner & outer axles. It will require some creative welding & fab work, but the housings are weldable, and other than time, it's more than doable. I have the parts lined up, just waiting on the old parts to sell to free up cash.
The issue is weight, the factory Meritor's are big & heavy, and the end goal is to get the weight down as much as possible & keep the price for the center section as affordable as possible, using as many junkyard/over the counter parts as possible.
Locker would be a spool or welded, I do not want or need a locker of any sorts, this is a mud bog/tuff truck type of application, no trail riding or DD duties at all. The stock meritor axles will be re-splined to 1.5" 35 spl to fit the center section. Tires are either 42" skinny boggers or 44-48" skinny ag tires.
My initial though is go with a sterling 10.25 (or would a dana 70 be better)? The trade off here is a heavier center section that is basically free, with an end cost of ~2g for the pair (less steering components/brakes & my time).
I blame the monster buggy for this change of direction, watched him compete at havoc and was sold on planetaries, but the weight is killer.
