Drive line vibration


IMG_0640.jpgIMG_0641.jpgIMG_0642.jpg

The brown one is stock 59 Pontiac, two black ones are from the 62, with new slip joint. It looks like all the new drive shafts are phased all in line as newer trucks etc. Found from Google search that the 90* phase works because cruise rpm is 2300rpm up with over drive rpm is about 2000 or little less. The explanation was related to the number of power impulses per revolution!  At faster speed it is 4/rpm in overdrive goes down to 2.6, engine now working harder and not as smooth (www.superchevy.com/how-to/engines-drivetrain/0205sc-vibrations/) where i found this. Original 90* phase going in, change latter if needed  Laurie

That sure looks good Laurie. I went a different route to rectify my vibration ( on acceleration) mainly because I already had the components. I replaced my original 700R4 dipstick with a firewall mounted one because the original one would not let me shim the xmission any higher to obtain a max. angle of 3 degrees between the xmission tail shaft and the 1st driveshaft. By doing this and cutting and re-welding 3/8 inch out of my hangar bearing to lower it I was able to stay within my 3 degrees maximum. I also had an adjustable upper control arm from Spohn performance to set my pinion angle. I also didn't like the way my original 1st driveshaft yoke stuck out of the rear of the xmission. I used the bigger and longer splined yoke from the 700R4 truck xmission with a reducing u-joint. I had to machine some material from the neck of the yoke and also cut a bit of the splined shaft to keep it from bottoming out in the xmission but now it sits further into the xmission. Well today was a beautiful day and I did my first test drive and It looks like it was successful. Smooth at 110 k too. I hope the pictures turn out.

Appears that you guys all have Canadian Ponchos so a Chevy driveline. Wondering if this would fit a 59 Catalina?

Rockauto lists a 59 Chevy center support bearing as a spicer 1280, no bearing listed for a 59 Catalina, so,likely not the same.

Had already checked out rockauto and a few other sites looking for a part number or cross reference. Thanks.

Presently trying to correspond with an outfit it Calif who appears to have it.
