92 SC3 Driveline Vibration Issue
Literally started on my lunch break a few days ago. Put it in first gear and give it half throttle and I get a BAD vibration in my seat and I'm hearing a weird squeaking sound from under the car. Second gear same thing but not as bad. 3rd 4th and 5th are fine for acceleration but at highway speeds and even in the city the car seems to wander a bit more then before whatever is going wrong is happening.
As far as what I've got new:
Motor mounts less then a year old (OEM)
New trans mount about a month old (Megan racing)
New center bearing in the driveshaft and flex coupler (2 weeks)
All has been good then something decided it didn't want to be good anymore.
To add: I did change my diff fluid because I did it last 45K ago and with this issue I don't know where to look: not anymore metal then last time however there was one small spec of a gear on the magnet which concerned me. But I feel this is a mount issue then a differential issue.
Open to any and all suggestions to look for.

the driveshaft must be at a slight angle , im going through the same thing right now in my aristo gs300..I shimmed the trans mount to raise it abit and it helped ...but im still dealing with it .. my motor isnt sitting leveled like it should ..

Check/re-torque nuts and bolts. There is an adjustment in the center support and it needs to align the shaft perfectly from engine to diff. Maybe you can jury rig laser beam.
