Indeed I had. I did not know that you had that type of half-shaft.
However, just a quick thought relative to your half-shafts.
We used to have a very similar problem with the splined shafts in the old FA (F5000) cars when Goodyear came out with the 15 inch slick. The loads on the splines were such that they would lock up (Not slide/change lenght) under acceleration and produce a very severe vibration. There were many tries at fixing this, including ball bearings in the splines to allow sliding under the loads. (The real problem was that the splines were not very good and too soft as well and would bind after a little wear.)
The fix was first Metalastic joints and then CV joints.
Maybe you have a similar condition and the splines are worn. |
