Spicer joints are top notch. They use them in the Jeep world, I have them in my rig. Very durable and high quality.

Stress tested the new prop shaft towing the boat and gear (1000-1200 lbs) over Shawangunk Ridge to White Lake today, 100+ miles round trip. I only had it up to 70 mph (because of the trailer), but everything was smooooooth and quiet. It’s not quieter than it was, but I never went into this project due to shaft or u joint issues; I started out just replacing the giubo to eliminate the rubber band effect, and replaced the shaft as a “might as well” after inspection of the rear joint (see above video). That joint had plenty of life left, as it showed zero signs of wear while in service.

I HIGHLY recommend Driveshaft Specialists for a replacement shaft. They’ve definitely re-engineered the unit to eliminate BMW’s shortcomings. I don’t think I’ve ever been more impressed with a new part, especially a “custom” aftermarket replacement. If you have to replace your shafts, don’t even bother with anything else, go with DS.*

*the pre-LCI cars can use the u joints from Rockford but the post LCI cars can’t without machining the shaft yokes. Adding up all of that, $525 shipped for brand new is a great deal, and the new joints are replaceable.

800-900 mile check in: happy to report the new shaft is completely transparent in its operation. I can't speak highly enough of the quality of the shaft build. They will DEFINITELY get my business for a custom aluminum shaft for the Olds: smoother operation AND freeing up some power in that car is a win-win!
