Hey everybody.

My car has had very bad power steering ever since it was bought. The steering feels heavy and there is a moaning sound coming from either the pump or the rack,I can't tell which one. Apparently it was caused by hitting a curb at high speed so it might have affected the rack directly. The steering wheel also jutters violently at around 100 km/h.

When stationary and turning the wheel left and right, it feels heavy and changes to light, vice versa.

I have attached a vid of the sound below,turning the wheel left and right:

What could be causing it?

The PS level looks ok,might drain it and refill though just to be sure.

Yeah I thought it might have been the pump,but if the car hit the curb is it possible it could have burst a rack seal or something? because that's where all the force of the hit would have gone.

could have burst a rack seal but that shouldnt cause the groaning that your getting, rain is easing sunday so suggest you chuck the car on some ramps and have a look underneath ,if you have any doubt bout possible steering damage then piss it off and fit another rack

Inspected the car today and found that the p/s pump is leaking oil quite extensively. The rack itself seems fine as it's not leaking and the boots are in-tact,no external damage.

Any tips or suggestions on how to go about taking this pump out and fixing it and what it might cost?

If you take the belt off, and remove the hoses, then the bolts holding the bracket to the engine it should come out.

Go to Nissan and see what parts are available for your particular pump. It should be similar to the r31 pump, then this might help:

So I did the overhaul on the pump, haven't put it back in yet though.

Now I'm about to do the overhaul/reseal on the rack itself,is there anything I should have to look out for/tips?

Aand, while I've got the rack out,is it worth buying new stiffer Nismo rack bushes or are they a waste of time? They're around the $80 mark both sides from RHD Japan, not too bad. Anyone had these?

Cheers.

      Yeah, my moulds and seals are 32 years old now. I think I will continue to not use a pressure washer on it.

      I hear the old "I'd never use a pressure washer on my motorbike" BS in the dirtbike community too.  The only people that have had a problem from using a pressure washer on anything are the people that aren't using them properly.  If you hold the wand any more than 45 cms away from pretty much anything (radiators, wiring connectors, paint, etc) you aren't going to cause any damage.  We've had detailers wreck moulds and seals on cars at work before and the only reason why is they held the pressure washer too close and on the one spot for too long.  If you have 5% more brain power than a detailer then you know not to not do that and you'll never have a problem.

      I'm pretty much healed up post surgery so I spent another almost full day out in the shed re-arranging everything to make room for all of the shit that I've taken off the car.  I need to get everything off the floor and away from the car for when I start making a massive mess stripping off the remaining body deadener and then for the the painting process.  Almost got the shed to a point now where I feel I can actually start working on the car again (clean shed clean mind or something!).  Almost 11 years of accumulated car parts, building supplies, tools, junk, etc have taken a long time to get in some sort of order again!  Most stuff is now boxed up and in the back shed if it's not car related.  Most people would still be horrified walking into my shed but it's significantly better than it was before!   For those that saw my separate post the other day, yeah I ordered one.... This version- I convinced myself to stop being a clown, wake up to yourself and realise it will take you 5 weeks to make one by which stage you're over working on the car again...  Maybe I am getting on top of my "mental ailments" and making smarter choices.... $1450 delivered which will take my miserable half-dutch arse a few days to get over having spent that much!  If I don't have a use for it straight away after my car is off it I might even see if there is a "rental market" for them.  See if anyone wants to hire it for a period of time.  $25 a week or something like that.  I'll worry about that when my car is actually ready to come off it though as that might be a while away!! There's now no excuses now for not ending up with an underside you could eat off! Away for kids sport the next few weekends so hopefully can get the rotisserie assembled ready to go for the car to go straight on it the next available weekend.

      I always use my Karcher, but it's only a little one that I picked up from Supercheap  The only issue I ever had with a pressure washer was when I was a kid cleaning coaches, they had a hi-po industrial sized petrol jobbie that would strip paint if you got to close I saying this, we have a fairly high power washer at work with a diesel powered heater that sprays water at about 60°c, it works great for removing old wax and road grime on the underbody after some foam cannon action, albeit from a "stand off" distance of a few feet

      Sorry no - The sandtrap adventure ended the day, happened at the end of the last session. At that time I wasn't hearing any weird noises nor were the brakes shuddering anymore. It was only when watching the videos that I remembered I had these sounds early on!
