Im in the process of shortening my Jag axle by 4" a side. Have done the lower arms by cutting and sleeving inside then welding back together but a bit unsure the safest way to do the drive shafts. I am thinking of cutting them and using a sleeve on the outside with dowl pins through the middle for good measure. Even if the weld was to fail the shaft would still be held together by the sleeve and the weight pushing against it. Does this sound ok?
