Geoff, thanks for the suggestion, I tried that after I rebuilt the ball and trunnion joint, didn’t run it at a high speed, but did not see any wobble or feel any vibration —
Thanks Sam, I think you are probably correct about the sagging springs. It’s the only thing that really makes sense. Going to go ahead and put the 2° wedges in. Will let y’all know how it turns out. Probably won’t be for a couple of weeks.
Thanks Darter6, waiting for the shims to arrive, hope to get to project next weekend. Trans mount is good per recent rebuild. Thanks for response, always appreciated.
Sam, the driveshaft is solid as can be — I (and others) have tried to find some play but there is none — and ball and trunion have been rebuilt and rear u joint replaced.
Geoff, ball and trunion functions smooth and easy, can find nothing amiss.
Doug, I ordered 2* shims from Summit and will let...
Motor mounts are good, yes OEM springs. I was wondering about cause of vibrations — thought is that gradual weakening can cause pinion angle to eventually cross the line of workable angles? Makes sense
Thanks khryslerkid and Doug — seems like the pinion angle is the primary culprit. The next step is to order some wedges and to tilt differential more downward. Never done this before. Is there any preferred provider of wedges?
This concerns by 1962 Plymouth Savoy. Four-door 318/727. The car has been in the family since new I have been the sole owner and caretaker For the last 45 years. She has slowly been developing a mild vibration on acceleration, close to a shuddering, that disappears around 15 to 17 mph. Between...
Thanks for the reminder. It took a while. I eventually ordered the kit from Mancini. The problem is most of the posts on differing forums are contradictory. Some claim that the adapter only fits a 318 LA and will NOT fit a 318 poly. In fact, that seemed to be the dominant opinion. Others were...
Thanks for your informative and thoughtful replies. I knew I could get additional perspectives from this forum. Still considering throttlebody fuel injection will let you all know if I go through with it.
Hey all, I am considering converting my 1962, 318 poly to throttlebody fuel injection. Looking for improved drivability, idle, etc. Interested to know if anyone else with a 318 poly has made the conversion and if so what your experience has been. Thanks!
Replaced the original starter a couple years ago with a new light weight unit. But I miss the unique sound of an original Mopar starter. Looking to have my old starter rebuilt. Can anyone recommend a rebuilder ? Thanks!
Changed the oil today on my 1962 Plymouth savoy 318 poly with the old canister type filter system. Been doing this for 35 years. I am so ready to switch to a spin on filter. Having a little trouble locating a vendor that supplies the conversion hardware. Any recommendations? All help is appreciated!
