Steering rack question

[Chev_350]

I just got the steering rack replaced in my VX Calais the other day and I don't know if it is me but something isn't quite right with it now.

I am out for a drive and I will go to turn the wheel and the steering feels okay, nice and light how it felt before the old rack went wrong, but then i turn the wheel couple of corners up the road and the wheel feels harder to turn. I will nd it is pretty much like these the whole time i go for a drive, light steering, harder steering, light steering, hard steering....etc etc,

What could cause this?

i'd say your getting a air lock in the system. try this....


have car parke din netural/park (whichever it is) pop the bonnet start engine pull the cap off the resivior for P/S and run it lock to lock
should bleed any air in the system (get a mate to watch if the level drops) while you do lock to lock

i just changed mine ,and you have to jack up the car, then turn the whell about 30 -50 times this gets rid of eny air in the system lock to lock makes it easy jacked up and dont stuff your tyers

[Chev_350]

Took the car back to the mechanic who changes the rack, as I can't jack the up and I don't want to mess my tires up dry steering. He said it could be the Variable-rate steering sensor......or the power steering pump,

[gungazza]

i checked the manual {max ellerys} could find nothing about"variable rate sterring sensor" eny body know???

Solenoid, rather than sensor? I am pretty sure that the variable rate steering operates open loop, using road speed as the input.

[Chev_350]

Think I got it mixed up, basically, he said it was what controls the how hard or light the steering is, he described it as a valve.......if its not that part he is going to see the power steering pump itself.

My first thought was a sticky pressure relief valve.
But your speed sensor solenoid could cause the same thing.

I know I don't have it on VT series 1. Not that it matters now that it's manualised
