I put a 90 t2 power steering rack in my 88 vert, it seemed to work fine for a couple of days and now it is making loud squeeling noises when I turn either direction, almost sounds like a rubber band streaching way to far. the rack was supposedly freshly rebuilt.

Are the racks the same or do I need a S4 rack?

 

belt slipping?

 

no, the belt is fine it is defently coming from the rack itself.

 

How's the fluid level?

 

maybe one of your lines is hooked up wrong?

 

ATF fluid level is on the money and the lines were labeled prior to removal and replaced in same locations.

My question is are the racks the same or do I need a S4 specific rack. the rack I used was from a S5 T2 90 model

My car 88 Vert

 

ATF??

Are you talking about the actual steering rack or the Power Steering Pump? If it's the pump, I believe that there are a few different style pumps used throughout the years that the FC was produced. I remember seeing a few FC's at the junkyard and each of them had a different PS pump... I'm not quite sure what that really means... Maybe you need to stick with the same year/model pump as the original...Maybe it doesn't really make a difference....

 

try using P/S fluid.

 

from what I understand P/S fluid in a RX-7 is a no no, if i am wrong let me know but my books say ATF.

 

Power steering rack is making the noise the pump is fine...

 

I've always used P/S fluid. even used that stuff to stop leaks, it worked fine

 

Back to my question, is the rack the same, whats the deal with speed and velocity sensors

Are the 90 t2 rack and the 88 N/A rack compatable??????????

 

some of you guys must know the answer to this question????????????

 

umm... ATF??? in the POWER STEERING??? i dun think so man. That sounds liek death right there.

 

Lol, its so funny that he just wants a simple yes or no answer and people keep ranting and raving about useless stuff he dosnt give a **** about.

But I guess my post isnt all that usefull anyways. Im honestly not sure, but i'll do a search cause im just that nice. (and by nice, i mean bored as hell)

 

Straight from the FSM

ATF type F (M2C33f) or dextron 2


I have searched and found the part numbers are different between the S4 and the S5. S5 have 2 different part numbers depending on chassis number.
All I want to know is are they interchangable or not?????
