Driveshaft prices are dropping

[36654]

... The space between the large diameter (~2 inches) casing of the front half and the smaller diameter (~1 inch) shaft of the rear half is filled with a high density rubber-like compound. I can't remember whether the same is true of the original.

Hmmmm ... I will say that I never looked closely at this area in either shaft.

Given the history of my current (original) driveshaft, I intend to swap it out for this new one sometime soon.

Looking forward to your feedback on that. I will likely not replace mine even at the next 12k spline service, unless needed.

Has anyone checked the old-style driveshaft for the torsional isolation material?
