Anyone know where I can purchase an aftermarket driveshaft for a decent price and that is dependable? I am tired of going through used ones seizing up on me, but that is to be expected with it's age I suppose.

Thanks

Mazdatrix.

Their drive shafts are the only ones that I know of with replaceable U joints.

 

www.dennysdriveshaft.com can make any drieveshaft you need.

 

Do a search. These things can be rebuilt. Some one just recently posted the info on where to get new u-joints and how to replace. Just because Mazda didn't design them to be replaced doesn't mean it can't be done.
Good luck,
