No brand new poly
I meant did you leave the bolts out or loose when fitting the shaft?
What for the carrier bearing? Never got that far with the yoke all the way in the trans still can’t get bearing caps in pinion yoke just a hair to far back.
Yes that’s what showcars told me as well.
Ya that always sucked about the 63-64 P/G's. I kind of wished I left my P/G in our car, as after I swapped in the Turbo 350 the car has always had a vibration no mater what I tried. The fix was getting rid of our 2 piece driveshaft and replacing it with a 1 piece out of an older Chevelle, worked out great. After our big car show of the year next week I will be taking out the Turbo 350 and swapping in the 200R4 I have, so that should be fun. Same length as the Turbo 350 and it has O/D.
Did you have it balanced? Did you replace the carrier bearing? Vibrations isn’t really my problem it’s more fitment. I’m going to a slip rear shaft. That should straighten out my problem.
Yes I tried everything and the vibration even after 3 engine changes also. Even my 4 speed did not vibrate like that, I suspect it's the Turbo 350 that's the problem. We'll see after I replace it with the other transmission.
Don’t have a vibration issue yet lol had fitment issue just a hair big which doesn’t make sense. Showcars front shaft with poly carrier and my stock rear shaft, which I’m switching to a rear slip shaft I’m thinking the new yoke is where I gained some length. I throw a pic up in a bit.
I had it to a shop they installed the poly carrier bearing and showcars front driveshaft. They balanced and did all new u joints. I forgot about the yoke being different between pg & 350 so at the last moment I purchased that yoke from Amazon! Ugh it’s a forged chromoly says usa but who knows. Believe me I don’t mind paying considering all the trouble I’ve ran into with parts these days. It’s awful!!
You are correct you cannot run a poly bearing without a slip joint driveshaft - I ruined a poly bearing in my driveshaft on one of my 409's.
Thanks for the heads up! Appreciated!
I had the same thing happen and i went back to the rubber support for now when i get time i plan on trying to make a one piece drive shaft work without cutting the frame ???
