I replaced almost everything, except the springs. Suspension has been the nightmare of an hour driving one way to work and it gets worse. Sometimes I feel like just waiting for something to really happen to see what it'* the problem. But I might kill my self into an accident.

I replaced:
Struts front/rear
Lower arm bushings/ ball joints
Outter Ball joints
Calipers
Break line
Engine mounts all three

So, can you describe the problem?

x2

and with all that work i assume you at least had the alignment checked :?:

Problem is:
A hard hit, almost feels that the whole car is going to fall a part, on road holes and uneven pavement.

When I drive slow it doesn't feel that much. But at 70mph it'* horrible. A lot of people would live with it. But I had been chasing this problem for almost a year now.. and have replaced all of above parts.

How hard is to change the sub frame'* bushings... and would an auto parts store rent the engine retainer.

Thanks

When your struts were replaced were the strut mount plates/bearings replaced at the same time?

Yep! strut bearings/mounts where replaced.

Tie rods have been checked and are good?
