Shaking over 60, how can I tell if my u joints are off?
Just rebuilt the zj 5.2 1996 from a blown head gasket, and had to take off the drive shaft tow it. It sat for 3 years before I picked it up, then I drove it for about a month before it started overheating. Found tranny fluid in the engine, swapped the radiator and of course all new gaskets. Now, while I drove it the first month, it never shook once.
Now that I've sewn everything back together, it's running fine but once I'm going above about 62mph, I get shakes which increase with speed and stop only when I drop below the 62mph mark. If my U joints were off (although I marked the drive shaft before removal to assure it was put back right) could this be the cause? I would have said alignment/rotate and balance, but it never shook until I rebuilt it, so it seems to me that that's got to be the cause. Any thoughts?
