well i recently put in a b series swap into my 91 hatch but i didn't have any money to put in the right kind of suspension so i recently came across a few extra bucks and decided is was going to do it right, reason being is when i hit high speeds and let off the pedal the front driver side axle or wheel starts to shack. i was wondering is that because if have a intermittent shaft with a d series right side axle or is it that i need a whole new suspension. please help me out i need to know what you guys think.

 

that's just an axles issues.
get the right ones.
and what trim level do you have?

 

starts to shake? sounds like a wheel bearing issue to me, jack the car up so that wheel is off the ground, grab the wheel at the "3" and "9" o'clock positions and try to shake it back and forth. then grab the wheel at the 12 and 6 o'clock positions and repeat.
