I have 2 driveshafts: one is the original 1991 aw70 shaft and the other is a 1986 m46 shaft (dl wagon if it matters). Right now I am using the front part of the m46 shaft and the rear of the aw70 shaft as the m46 rear shaft has a blown rear u-joint. The m46 one seems to be much thicker because it has some sort of internal damper, I read.
After a week of driving on the aw70 one, I seem to like it better. I think it drives more 'firm' and has less rotating mass, but i'm not sure if its just placebo because I was used to a bad u-joint which mucked the old m46 one up. Has anyone else noticed a difference?
so: should I replace the u-joints in the m46 one and put it back in, or should I do the u-joints in the aw70 one and keep using it. Will using the non-dampened aw70 one mess with the overdrive or something over time? Why did they stop using the dampener later on in the m47/aw70 ?
Also, does anyone know off the top of their head what u-joints I need to buy to replace them in either drive shaft? Where do I measure on the joint to get ie 2 5/8", 3" or 3 3/16" ?
Thanks for any input
