S13 steering "sticky" or "heavy". Assistance please.

[LockOn!]

Hey all. My power steering gets heavier after I have driven for awhile. Also, the steering will "stick" to whatever side I last turned. Yes I used search and google lol.

For example, if i turn right off of a main road on to a side street and let the wheel return itself in my hands, it will stick about 45 degrees to the right and I will need to straighten it manually.

When I first drive the car to work in the morning I don't seem to have this issue until I'm about to pull into work 25 mins later. It seems to only occur after the steering is warmed up, however I think it's been slowly getting worse over the weeks.

Do you guys think this is more likely an issue with my rack or the pump?

I have no idea what is in there fluid-wise p/s or atf. I know it leaked a bit from where the steering column meets the rack but it stopped after adding some Lucas stop leak (I know, janky, but I've used the stuff, and seen it used by others with success before.)

Again, rack or pump problem? Thanks

Ok, replaced the fluid with fresh red ATF. The old stuff was mucus color, I take it ancient PS fluid.

Now the steering doesn't wine and creak near as much. Still feels heavy though, doesn't stick quite as much.

Suggestions?

Ok, super groany again, espcially after warmed up for the first time each day.

Someone told me its because I have an air bubble in my rack that is overheating my fluid turning my steering into dog shit.

I think im bleeding it properly? Jack up front, turn car on, turn wheels lock to lock, remove 75% of old fluid from res, refill, repeat until no bubbles?

I have no bubbles, but my fluid doesn't swirl in the resivour, it does but SUPER slowly. is it suppose to swirl faster?

INPUT PLEASE. I dont wanna break down and throw cash on a new parts if I don't need too.

its your rack.

also, if ur alignment is out of whack severely, your car will not return to center at all.
