I need to shorten the driveshafts on the 200sx axle I have narrowed, I would have normally male and femaled them to the right length, sweated them together and welded the two halves. I have now found that the shafts are case hardened which made me ask Zane at Zannetec for advice.
They will not be used on the drag strip or in anger but he suggests that the material either side of the weld will be compromised and be the weak point.
His solution would be get them friction welded or new ones made/ re-splined.
So where do I go for Friction welding or getting the shafts modified?
New area for me so suggestions please.
