Welding axle brackets, do I need full penetration?

I got the Ford 8.8 brackets yesterday. It's from MORE and the spring perches are 1/4 inch steel! As I gathered so far the tube wall is at most 3/16 inch. Question is will my welder - which is rated up to 3/16 - be good enough to do the job? Do I need full penetration on the bracket or just enough to hold them together? As I recall the factory brackets were also 1/4 thickness and were not welded on with full penetration. Only the outside edges were welded and penetration was about 1/8 into the bracket material which I could do as well no problem. The hole kit is very high quality btw. Things are slowly lining up...

Re: Welding axle brackets, do I need full penetration?

All I did was set the pinion angle and tack the perches in place, I then removed the rear from the truck and welded the perches completely. I did not penetrate all the way through the brackets or tube, and dont feel it is nesacary to do so. A 1/8" bead penetration should be plenty strong to hold the spring perches on.

Re: Welding axle brackets, do I need full penetration?

Ok, thanks. So since I'm doing an SOA I'd need to set the pinion angle around 1 degree lower than the tcase, is that right? What about the shock mounts? Can I raise them compared to the stock setup to gain ground clearance? Maybe I should wait till I get my shocks and see just exactly how much travel I get up and down. The shocks should be mounted so they can travel an equal amount up and down, is that right?

Re: Welding axle brackets, do I need full penetration?

The shock mounts can be mounted a little higher on the tube, and the shock should be positioned at mid stroke with the weight of the vehicle on the axle, this way you will get an even stroke up and down. Also shocks are designed to work best with the piston just about in the middle. In reality though, your bump stops might not let you suspension travel as far up as down so your shocks set at mid stroke might top out before your springs do.

I wasn't sure on this subject so I went and consulted the wife. She advises that you should always achieve full penetration. Hope this helped [img]/wwwthreads_images/icons/smile.gif[/img].

I new somebody will get smart on me! [img]/wwwthreads_images/icons/smile.gif[/img] Like I don't know about penetration, we're expecting any day now! [img]/wwwthreads_images/icons/shocked.gif[/img][img]/wwwthreads_images/icons/wink.gif[/img] Anyway, the kit was $100 through Offroadtoystore.com. It has very high quality laser cut 1/4 anti-wrap perches, shock mounts, custom sized ubolts and plates included.

I've boogered the factory perches while grinding them off so I couldn't reuse those. I don't have a torch or plasma cutter to cut these parts with a good fit. Since I don't weld like a pro I wanted a good fit. I'll be making the shock eye adapter brackets myself since those are pretty simple and RE wants ~$25 for them. I can't believe this guy doesn't want his welder back yet. I had it for some 2-3 months now. [img]/wwwthreads_images/icons/smile.gif[/img]

Re: Welding axle brackets, do I need full penetration?

Oh..and for the pinion angle, are you running a cv? With a cv shaft you simply point the pinion almost straight at the output and the cv makes up the difference. With a standard shaft, set the pinion parralel to the output. If the angles aren't even you will get a vibration. With that much lift I would run a cv and SYE, or atleast a SYE and a longer shaft to eleiviate some angle.
