[QUOTE=chicov8;8273732]i never drove any other gs but used to have ls and gs sterring is much much stiffer The GS is all way smooth and handles easy like silk.and i have a 430 so i think it may have the L-Tuned ECU,With that said i think im gonna to try to get a 400 ecu mayde that will feed more assist to the pump and rack another thing is im gone to change those factory clamps on all the ps hoses with the ones that screw

Must be a 98 GS right?

I greased my upper ball joints and it helped some (I use a 18 gauge grease needle) and it helped make mine a bit easier. Mine has always been on the stiff side. Mine is just over S/N 4000 in 1998 (my car made in 1997), so a pretty early GS4.

Okay i will try that tomorrow because it feel like something needs to be grease so we will see thanks.any other suggestions i need all you guys input because this is my dream car and if this dont work i plan to get a 350 electric steering

If you haven't greased the bottom ball joints, by all means do that too. Do them all while you are there.

daddyduke

Cool i promise thats what it feels like im praying this help i love my gs4

I think it helped mine. I don't know if a LS PS ECU will work, but that one might boost the pressures for more assist too. My wife still thinks mine is too stiff, but her Buick is a bit on the overassisted side too.

I need to find the PS ECU and look at it, might be something to work with and modify....

i have new upper control arms and lower ball joints (moog so i grease ball joint with every oil change last time lessthan 1k mil) still very stiff

I guess something we should characterize.

What is stiff?

Stiffer than a 1969 Ford Galaxy?
Stiffer than a 1987 Acura Legend? (most awful steering on the planet)

Or stiffer than a 1970 Mercury Cyclone with a 429 SCJ with manual steering?

How hard is it to make it too stiff?

Not that I recommend it because it is something much easier to get wrong than right, but the tension of the rack can be adjusted. It's possible at some point it was tightened to compensate for wear or a slight front end vibration.

daddyduke

i thought about that to but i no when this stared to happen it would be smooth for a day then stiff the next then smooth then it went stiff and stay i felt like something was going out,But i will try that today.

daddyduke

i never drove any of those cars.I had a 08 g37,99 es300,97 es300,02 TL s Type,My gs430 is harder then all.It feels like im driving on flat tires best way to put it.

RamAirRckt

The Legend, you have zero road feel, you can gently spin the steering wheel and it will spin to the other side and bounce back. It was awful.

The Galaxy similar.

The Cyclone, you needed to be Mr. Atlas to drive it. Stopped, you weren't turning the wheels....

If i drive my car longer then an hour my forearms begin to hurt.
