OK GETTIN MY ROCKWELLS AND I NEED A FEW PICS OF THEM INSTALLED THE PICS IM MOST INTERESTEDS IN ARE OF DRIVELINE .. AND I SEE PEOPLE TALKING ABOUT TURNING THE DROP OUT 180 DEG HOW AND WHY PICS

flipping the center section 180 deg. as shown, gets the pinion centered... This only works on a front end for rear steering use. If you flip the carrier on a rear Rockwell, you'll just move it from one side to the other, which is pointless. As for the pinion brake, it's been beaten to death, please search.

IS IT THAT SIMPLE JUST TURN IT AROUND????

nope, you gotta drill and tap like 6 or 8 new holes, somethin like that. Jeeper111 will see this post soon, and he can tell you exactly what he did, that's his POS heep...

Gotta drill 8 new holes. Im in the middle of doin mine now. :rolleyes:

KEEP THEM COMIN

i helped jeeper flip his pinion, it wasn't that bad we did it in about 2 hours. the hardest part was marking where the holes go because the pinion is in the way. I put the pinion down in the axle and spray painted where to mark the holes

Not to hijack your thread but I was wondering if anyone had rough measurements of the steering axle (length overall, height and depth of the tubes) and the rough height and width of the 3rd member; Finally the location of the center of the third member in relation to the knuckle kingpins would be nice too:

Reason I ask is I want to start work on the basic frame for my 43' MB and need a few measurements to mock up some crude dummy axles until I can get a pair of the fronts.

I am planning to set it up using two fronts so the front axle dimentions are the only measurements I need...

Thanks and :beer: :beer: :beer: to who ever take the time to run a tape measure!

elf get out that measuring stick and get the man some number's...ya have no job, the axles were out...so it should be real easy....tell you one thing you better have a good lift and strong back for those axles.....

I SEE PEOPLE TALKING ABOUT TURNING THE DROP OUT 180 DEG. If you are going to drive this on the road,the 2 1/2 ton front has 2 degrees negitive castor, it is difficult to drive on the road,when you turn it around it becomes 2 degrees positive castor and it helps, but 5 on 6 degrees is ideal. steve differential eng. inc.

actually, they are back in already. Got a few more things to do tomorrow, and then be done with it. Here are a few basics:

WMS with hubs flipped out - 79.5"
WMS with hubs in - 69.5"
Axle tubes are 3.75" square
length overall is about 83-84"
pinion center is about 8" above axle centerline, top of carrier is 3" above pinion center.
pinion is offset about a foot from axle center.
the center of the center section is about 8" off from center.

HTH!

The caster doesn't matter because your just going to be flipping the carrier in a rear steer app. anyway and you wouldn't use that on the road. I think your talking about flipping the whole axle which I didnt do because I knew I would need a CV in the rear and the negative caster helps to cut down on how far the tire lays over in the back. I believe I am in the neighbor hood of 8 degrees of caster set to the right angle which should be just fine for a rear steer app.

Thanks! Those are pretty much everything I need - the only other thing I was wondering about was the diameter of the third member - your saying about 11" above axle center line and the middle is 8" from the middle of the axle, but how wide is the whole deal - bolt hole to bolt hole along the axle tube...

I also found a local fire dept that has a sweet duece converted into a fire truck for wildfires - I am going to stop and talk to the guy who is doing all the work in the next few days, I can get some better dimentions off the front end of that one if anything else comes up; Thanks again
