Shaking 1997 Oldsmobile Achieva

My car sometimes shakes really hard when I drive around 40 mph. I’ve replaced the wheelbarings on both sides, the rotars, the front tires, had a wheel aligment and replaced the tire rods (both inners and outers on both sides). Im scared to drive on the freeway because of the shaking. What else could it be?

CV joints or a bent rim.Ball joints, but whoever did the alignment should have checked the ball joints.

I’d add motor/transmission mounts to oldtimer’s list.

I’ll have to look in to that when I have the money to get it checked out. Thanks. i’ll keep you posted.
