VR4 4WS

lol, Ok Kaya, PM me an offer... do you need the inner tie-rods as well? If I pull the inner tie rods off it will be a lot smaller to ship.
I've just cut the rack boots off to check for leaks ( they were ripped anyway! ).
No PS fluid in either boot and no red staining anywhere around the rack. You will have to put new boots on it and I'd replace the tie rod ends as well.
I've also pulled the lines off of it so you will have to reuse yours. Go to Mitsubishi and get some new orings for the lines as they suck to change in the car!!

Does anyone have an understanding of how the rear steering actually works and can explain it to me. I want to know what parts of it move causing the wheels to turn. I have deleted my rws, welded the arms and removed the rack and all associated lines. Im in a pickle about if i have done enough or if i need to replace the rack with a solid bar.


Cheers

If you just pull the rear rack you will have what is called Passive steering.
I got rid of mine years ago and never noticed any issues with it gone without adding anything else.

The RWS in a Galant is only for higher speeds, it works by using a rack similar to the front and unlike the system found on a late '80s Prelude can't/does not steer in the opposite direction at low speeds like car parking or tight corners but only steers with the direction of the front to assist in stability at high speeds.

A passive rear steer system uses rubber bushes of varying density and uses vehicle inertia to determine the amount of steer, this is usually only slight and in cornering at speed.

Taken from Wiki "The passive steering system uses the lateral forces generated in a turn (through suspension geometry) and the bushings to correct this tendency and steer the wheels slightly to the inside of the corner. This improves the stability of the car, through the turn. This effect is called compliance understeer"

There is a lot more to it than that of course

Passive systems that I can think of are ones used on Proton Satrias and some others I can't recall and is fairly common

Active systems are more complex and have to be controlled by an ecu of some type, either stand alone or integrated depending on which car it is. The new porshe 911 GT3 and Renault Laguna

I the case of your VR4, see if you can pull up a pic or diagram of the rear of an RS, they didn't have RWS, and cross check it with yours

Sorry if I'm not more help

RS uses the same rear end setup as the stock VR4 hence my comment.
The 1G Eclipse also uses the exact same setup.

So Brisvr4 all you did was remove the rack and lines and thats it?

 

[brisvr4]

Yep, in about 2005 i think it was. Zero issues since.
