I ordered new ones from Amazon. replaced u-joints at the same time. Less than $150 and you get a whole new driveshaft. Takes about 2 hours
I filled my carrier bearings and, now with the driveshaft installed, I can't push it far enough to hit the floor. My carrier bearings were cracked very badly. The silicone squished out multiple cracks in the rubber. I did see a crazy low price on 2 carrier bearings on Amazon. I will get them and get them ready for install before drag race season starts. I was thinking of bringing the new bearings to a local windshield place and have them filled with poly eurothane. I would think it would work just as good and last much longer.
Thanks slowdsm for the link!!!!!
