Hey guys. One of my 1992 Previas has a really bad vibration issue. It started Monday and I can't figure it out. The van seems to only have the issue when the van is in gear and the vibration is only while accelerating. I've rotated the tires, checked the rear driveshaft (no play in it), my fluids are fine, the engine is running smoothly. I've also noticed it starts at around 20 mph and seems to go away once I get to around 50-55 mph. The vibration can be felt through the entire van. I had the SADS bushings replaced back in '09, but I'm thinking that could be my problem again. I just had a JDM motor installed in this one 6 months ago if that matters. Any advice is appreciated.
