Okay so here is what i have done. I had the front wheel bearings changed,

balljoints on both sides are new, new tokico shocks with stock springs, and had it

aligned 3 times. The last time i had it done it seemed like it was okay but it still

pulls to the left a little at high speeds. I drove it from Austin to El Paso and El

Paso to Austin. When i was driving the car at like 80 mph or faster the car

swerves left to right like if something is loose(when i hit bumps it is really bad-

can almost loose control of the whole car at high speeds). I dont know what

else to do. The guy that worked at pep boys mentioned something about the rack

and pinion but did not catch exactly what he said. Has anyone ever encountered

this problem?

 

have you checked the entire suspension for broken bolts, broken sway links etc...?

 

It sounds to me like you have a broken bumper sticker........

 

DTSS bushings shot?

 

thats what i'm thinking

 

Worn out bushings is the most likely.
The alignment shop should have spotted them.
You may need to go to a different shop.

Another possibility – dirt or wear in the steering rack.
To check:
Jack the fronts off the ground.
Push the tire left & right to feel for any rough spots in the rack travel.
Then start the engine & slowly turn the steering wheel left & right to feel for any rough spots.

 

Does it feel like the rear end is moving around? or the front? I've got the same issue, but I just got done repairing some damage from getting run off the road into a curb. So It definately needs an alignment, if not more work.

 

Are you talking about the bushings on the top of the shock where it settles?

 

my 88 se has the same problem, i think it is the dtss bushings, but i havent really looked at them yet. I was following someone else driving it, and it looked like the car was driving slightly sideways, like the dtss gets stuck to one side or the other

 

I would think that it would be DTSS bushings or the control arm bushings as well, but do not rule out that its just the wind.

 

It would help if you tell us which year RX-7 you have.

Most likely, worn out end links (either 89-91 "dog bone style" or 86-88 "replaceable bushing style"), old DTSS bushing (use eliminator bushing instead), or subframe end links are worn out.

 

the year of the car i have is 1988 mazda turbo 2.
