94 jimmy. Had a vibration last time I drove it. Had the original tires-wheels on and didn't think much of it. There old and worn out. I put the 33s on and vibration went away only on city rds. On highway it got worse and herd a big thump and hole trucks shaking. Limped it home and found this. Glad the drive shafts didn't fall off while riding. Thays what I get for getting cheap parts.
