Shudder when accelarating- Drive-shaft
Ok i need some help. I had some horrible vibrations that led me to replacing the center bearing on my drive-shaft. While it was off i had them replace the u joints as-well. Now when when i first start of i get a horrible shudder when accelerating from about 5mph-10mph and never reappears until i have to start and start again. It never did this before.
Here is what i probably did wrong, at least i think. Under advisement from a mechanic "friend" we didn't mark anything when we took the shaft off. We also didn't have the drive shaft balanced. He said that you dont need to worry on these trucks about it going on the same way it came off. I need to fix this! I am afraid that i am going to screw up the truck more if i keep driving.
If this truck isnt running i am not making money.
Thanks in advance for any help.
Also we tried spinning the rear section 180 degrees
