hi everyone, have a project i was looking for help/tips/guidance on. my older off road UTV (never street driven) has been eating ball joints and i think i found the culprit. on one of the rides the castle nut on the ball joint fell off which allowed the ball joint to open up the tapered hole in the a-arm (see pic).
has anyone ever had to repair anything like this?
the a-arm was custom made by a company that is no longer in business so i am trying to fix this one. i can tig, mig, and stick but do not have access to a lathe or mill. my thoughts were to tig weld and build the walls up, then taper ream it back to original dimensions. i have also seen weld-in taper sleeves but am not sure my drill press chuck could handle drilling the a-arm out to accept the sleeve.
any ideas or tips? i think the taper on the ball joint is a 7 degree taper based on my rough measurements. if anyone has tips on how to measure taper too i would be grateful.
