DD probs again

[jlagnese@massed.net (John Lagnese)]

Hi,
My 91 Jetta Gl almost bounced off ther road yesterday. I was on I-95 N
in Amesbury, MA. There is a curve and a bump in the road. When I hit it
at about 80, the car almost jumped off the road. It felt as thought it
almost came off the ground and did a bounce. This is a bump I have
uneventfully driven over in my 87 16V and my old DD, an 83 Audi 4000. I
have recently replaced the tie rods, struts around, and ball joints. Any
ideas as to the cause, or a solution?
