Today I finished one of the rear upper control arms. These were a lot more difficult to make than I thought they would be due to the need to maintain the angle where the control arm bolts to the upright. If this was flat then the arms could have been a super simple standard A-arm design.
I made the welding jig for these arms a while ago but had to put some finishing touches on it before I could begin.
I was only able to use my tube notcher for one of the notches, all the rest were done by hand. I also used a printable notch template for one of them.
95% of it was welded in the jig and the rest had to be done with it removed for better access.
The finished product, you can see the angle I was talking about.
and how it mounts to the upright
I think it came out nice, decent weight savings too as those OEM arms are super heavy! I think this is the first time my arms have been lighter than standard.
Once I have fabricated the passenger side control arm then that is all the suspension control arms complete.
