I did that on my NAERC Diablo , Audi to GM, I had a pro truck welding shop to weld., they told me some shafts as GM the shaft is a lot more stronger. needs special way to weld. they made a sleeve to extend and joint. by MIG that not good.

I haven't done it, but I have seen many results from people who have. Axels are heat treated tempered steel that when cut and rewelded (whether shortened or lengthened) lose their tempering and are prone to twisting and failure at the weld points. Even people who go through the whole process of adding sleeving over the welds just make the matter worse. Its not a matter of if it will fail, just when it will fail.

CV Axle modifications
« Reply #1 on: May 13, 2025, 02:25:31 PM »
I designed my car around using Lexus CV axle which have the 30 spline end and same bolt pattern on the Audi 01x transaxle. Unfortunately because the Aventador is wider, the CV axle I need are roughly 3" too short.  Has anyone cut and sleeved a CV axle to get the proper length? If so, who did the work and what are the downsides?
