R34 steering rack

R34 steering rack

Anybody know if there is a difference in an automatic steering rack and a manual one on the r34??

i have a plug on my alternator loom for the steering rack but I have no sensor on the rack for it to plug into, thinking i may have an auto steering rack?? My car is a factory manual

 

first photo is my rack, and second photo is one of the net

Sorry not sure but I can confirm that what was sold to me as a 2door rack did not fit my 4door, different length bolts or something. Recommend checking that too before you buy.

The plug should go on the hard line before it enters the rack, not on the rack itself, trace from the high pressure line and you should be able to find it, I think it's near the oil filter area

My r34 steering rack definitely didn't have any sensor or valve and it's a manual

Okay well I've looked at a whole heap of photos, manuals, turbo and na, and some have the plug and some don't, so I'm assuming it's been changed over the years or something, thank heaps for the reply

Sorry my bad
Had a look at my car last night and there IS a brown plug on the rack

Can't really see the plug but you can see the harness coming out of the rack

There is another plug on the high pressure line tho, might be that?

I Did tell you about this in your other thread.

Does your steering feel heavy when driving around parking lots? The plug on the rack is for the power assist solenoid. It controls how much assistance the power steering gives, Lots at low speed and not much/none at higher speeds

The switch on the pressure line is for idle. When you steer it bumps up the idle, especially important when the air con and alternator are working

Yeah see mine doesn't have that harness Coming of the rack, it's for the idle control when steering, but I don't know why some racks have them and some don't

Yes and that helped me mate thanks!

 

The plug is for the idle control but I've looked at different photos of different racks and some have the plug and some don't, my rack hasn't got it but my loom does because I changed it

Interestingly there is a mechanical valve that comes off the PS pump on the banjo that controls the idle. I've taken that off and blocked it when I changed my pressure line, just raised the idle a little

My guess is the one on the rack is could be for variable steering assist? Could be a HICAS model vs non HICAS model difference?

These r34s are a bit more complex than r33 I found...

I thought it could of been for hicas models too but I'm pretty sure hicas only affects the rear steering racks

Hrm but the HICAS ECU controls variable rack assistance

Hmm it may be for hicas then, well whatever it is my car doesn't have so I don't need to worry about the extra plug!
