pulsing in a constant turn

[benjammin]

What is the main cause of this?

 

[Racer X]

If you mean pulsing in the steering wheel, probably your PS pump going south.

 

[benjammin]

I just replaced my pump with a new unit.

 

[VortecGT]

steering rack or the vaps system

 

[Racer X]

Oh. Well, I guess that's ruled out.

Is your car equipped with VAPS?

 

[benjammin]

how can i tell if it has VAPS?

 

[benjammin]

do you think the pulsating could be air in the system?

Pulsing as in it seems like the assist goes in and out slightly? I think that's pretty common and has to do with the valving in the rack. I have a reman rack and it does it a little, too. I'm using ATF in my power steering sytem, though...so it might be from that.

Start by including your year and transmission in your signature (or at least in posts when you're asking a question about your car) so people have some information to start with to help you out.

Does the pulsation you're feeling feel like it's pulling back on the steering wheel a hair on you, somewhat rhythmically?

 

[93rev2sev]

That's what I feel and I think that's what he feels...but we'll see here soon...your description was a lot better than mine.

don't mean to high jack, but my steering does that. what does it mean? also it faded when i got new tires and an alignment, but its still there a bit.

 

[benjammin]

yeah thats what I mean...but often its more than just a hair. Also, it seems to have gotten worse AFTER i replaced the pump

The rack is making the "sawing" motion that you are feeling.

 

[Vnuk1]

Mine kind of does that until the car warms up then stops.

Exactly.

Been there, fixed a couple of times on my old 89. Finally got a good rebuilt rack....

I have a 95 ATX and I hate that pulsating sensation when im turning the wheel. Just curious can a Gen 1 steering rack be put in a Gen 2 ATX?????

 

[SHOGUN88]

I have the same problem, ill probally replace the rack at some point.
