[Low Elco]

Not for nuthin, I chased my tail on my EC S10 for a couple months like this. Stock carrier and double cardans, nice and smooth. Factory carrier finally died, and no biggie, I swapped it. Vibration like crazy. Destroyed the OE gettin it off, so no comparing. The first cheapo died pretty quick, so I got the super bad boy one. Same problem. Got a whole different single cardan shaft, better but not great. Finally got out the math and did some consultation. Rearend angle and trans angle were dead nuts the same. So, I said to heck with it and cut the Carrier mount loose and dropped it a good bit and made the first shaft basically straight and square out of the trans, and a complementary angle to the rearend. Smoothed right out. I believe for whatever reason, the aftermarket Carrier bearing is significantly taller. I don't know, but it worked, and I have my truck back. Good luck in your quest.
