Re: Violent shake.
My '49 had this same thing happening when I got it.
I had 2 NEW miss aligned hub/bearing assemblies. Final solution was NOS hub and NOS bearing that I assembled making sure the bearing was seated correctly to the hub. It's been smooth as glass for 3k miles now. |

Re: Violent shake.
What would cause the pinion angle to change from a stock set up? Have you changed the rear end components?

Re: Violent shake.
I went through this chatter deal on the truck. Turned out to be a bunch of small things... all adding up.
-several items in the pedal linkage were worn out or ovalized -engine mounts needed replacement -that dinner plate style flywheel wear scenario in post #21..... or something very similar was going on with mine. When I took everything apart for getting the engine rebuilt, I was surprised at how wonky that flywheel/disc/pressure plate interface had become under the previous owner's care or lack thereof.

Re: Violent shake.
A lot of good info here. I'm planning on taking things back apart and check things.
Please keep giving your thoughts and I appreciate it all. |

Re: Violent shake.
If you are going to inspect or check pinion angles just be aware the stock 50 uses what is known as a "broken back" system of alignment. If the front u joint angles down the back will also angle down and the angles should match each other. This minimizes driveshaft hump in these cars but stresses the joints as everything moves up and down.

Re: Violent shake.
Some mid 60,s Studebakers also used this system. It is not a "wrong" system just a different system to prevent driveline vibration. If the cars suspension heights were messed with; front and or back, it could cause a problem but I am guessing vibration at speed would be more likely.

Re: Violent shake.
So I sent my clutch parts to Fort Wayne Clutch today. A gentleman named Lou is going to check them out. Lou ask me to send the new parts I bought from Shoebox Central. I'll but anything he says is not useable or rebuildable.

Re: Violent shake.
I am in agreement with alchemy. Seem like correcting the brokeback pinion angle could not hurt.

Re: Violent shake.
Update on Violent Shake. It's fixed. I'd like to thank Dick Mortieay. He helped me figure out that I had a Mis matched group of parts. The car is a 1950 ford custom. Turns out it has a later modle Merc cast bell housing. It did have the 50 ford throughout bearing. The bearing did not fit correctly on the Merc arm. Ultimately I sent the new parts I bought from shoebox central to Fort Wayne Clutch. They did there magic on them and also sent me the correct throughout bearing for the Merc bellhousing. Put it all back together and it's good. Thanks to all for the responses also.
