  • Axle wrap on spring over

    In the process of swapping in full width, I am lincoln locked f&r with 38 boggers I like to mud bogg can I install one pan hard bar to top of pumpkin on rear to the frame or should I do two off each side of housing up to frame What should my pinion angle be now that it wont pivot.

    your pinion angle will depend on what type of driveline you are using...

    if you are using a CV joint driveline, then you will want the axle yoke pointed at the x-fer output yoke (usually like 1 degree lower for slight spring wrap on acceleration)

    if you are using a non-CV joint driveline, then you will match the angle of the axle yoke to the angle of the x-fer output (use a magnetic angle finder tool to find angle.. they are cheap)

    You can set up the traction bars in many ways.. some do it off of the center housing, others have done 2 seperate bars.. it is personal choice there....

    hope it helps....

      Most people use a Traction Bar similar to this

      We sell this particular kit, but other companies like Skyjacker make them also.

        i like the bam bar idea

        http://www.jeepaholics.com/support/t...hTerms=bam,bar

        there are a couple write ups on it on jeepaholics, search and you'll find more.

          Hey fubar and anybody else that wants to chime in got this running gear in just little problems like steering linkage I got raised steering arm but the shaft between pitman arm and steering arm seems to be to short and can I turn the pitman arm 1/4 turn or will this affect my turns from lt to rt. Can anybody out there give me some heads up on anything else I might be over looking. Thanks to all the Ideas

            if you 'clock' your pitman arm you will loose turning radius as that affects the geometry of the ability for the arm to push or pull your steering knuckle.

            I have seen some people take a piece of DOM and actually use it to sleve and lengthen the drag link (the bar between the pitman and knuckle) and then weld the DOM, of course.

            You can also go to your local parts house with a length measurement and possibly get a longer one, like maybe out of a later wide track CJ, as I believe that those were longer bars (can't remember).

              when i did mine i got some DOM from a local supplier, got some threaded inserts off the internet, then welded them in. i think I have about $50-$70 total in my drag link and tie rod together. you could get some DOM, cut the tie rod, then use the DOM as a coupler to space out the cut pieces. i'd drill it and plug weld it if you go that route.

                Hey Zoediak not sure what "clock" means but must pertain to rotating pitman arm like chevys I went with a longer draglink and left the pitman arm in original position like the cj's are. what does DOM stand for also. Thanks again.

                  blkforddiesle, by 'clock' I was referring to your statement about moving your pitman arm 1/4 turn... If I remember correctly,(brain is old), the pitman arm has a master spline in it anyway that will not allow it to be 'clocked' or moved on the box other than it's standard location.

                  as for DOM... that stands for Drawn Over Mandrel, it is a way that the steel manufacturers process the steel tubing.

                  there is also HREW (Hot Rolled Electric Welded), CDRW (Cold Drawn Electric Welded), or ERW (Electric Resistance Welded)

                  see this link below... it basically shows a difference in the drawn over mandrel or the rolled/welded
                  http://www.steeltubeinstitute.org/pr...m_Process.html

                  The DOM is going to be the stronger of the tubes (tensile strength), this is why it is used, more often than not, for roll cages and the sort.





                  *****here is a bunch of information on tubing******


                  DOM, ERW, HREW...all types of "mechanical tubing", as opposed to pipe. All mechanical tubing is dimensioned by OD and a wall thickness.

                  DOM is actually not a type of tubing, but a process that is applied to tubing after it is initially constructed. It is Drawn Over a Mandrel...which "cold works" it, giving more exact dimensions, smoother finish, and better alignment of the crystal latice structure. It is Not seamless tubing, and it started life as some sort of EW (electric welded) tubing. Most commonly, when people say "DOM" they mean 1020 mild carbon steel rolled electric welded tubing that is then drawn over a mandrel.

                  Other mechanical tubing that is not necessarily drawn over a mandrel can be either hot or cold rolled (i.e. rolled from a flat strip into a tube when either hot or cold) and most commonly available will then be electric resistance welded to form the final tube.

                  Generally...cold forming and cold working add strength and uniformity to a product, and reduce stress.

                  -----------------------------------------

                  So VERY BASICALLY, in terms of strength you usually have, in order:

                  DOM
                  CREW (cold rolled electric welded)
                  HREW (Hot....)

                  Again...these are all just processes, to fully call out the material, you need to specify the type of steel...but most commonly we are talking about either 1020 mild carbon steel, or 4130 or 4140 Chromium molybdenum alloy steel or 4340 nickel chromium molybdenum alloy steel.

                  I hope that some of the information above helps you out....


                  but if you decide to sleeve your link with pipe, do as suggested by someone else and drill some holes in it to puddle weld the pipe to the link. This will ensure a stronger bond with the pieces.

                    Thanks Zoediak that was some info wow, anyways the pitman arm and steering box shaft has (4) 1/8 in teeth along with splines it is possible to clock it but I lft it in stock position gonna try it their.
