Rack might be failing internally. Have you checked under the rack boots for possible leakage. And I take it it’s not possible to connect the rack pipes back to front? Not seen one close up, only diagrams so not sure if it’s possible to cross connect flow and return pipes.

Hi.
Due to the design of the metal pipes it is impossible to put any of them on wrong. Which would have been a easy fix if it was so.

I have just changed the sepintine belt but the old one looked nice and clean and dry. It had only been on about 18 month when I don't the timing belt change.

I'm just away to remove the steering rack boots and check them but I can't see it being a leak as I'm not loosing any fluid and so far there is no visible leaks on the rack, boots or pump ar anywhere near.

The rack was working fine before I changed the pipes and seems to work fine when she is on axle stands. Only getting heavy steering when she is on the ground and at idle. It eventually goes back to more or less perfect steering as it should after driving for a while but then now and again it goes so hard I can't steer, obviously very dangerous if I'm not careful. Thankfully I have a large empty carpark close by to do figure of 8 turns etc.

But when I leave her for 10 mins or so then it goes all hard again .
It definitely seems like a air in the system issue. Trouble is how can I force it out when the car is on the ground. ??

Things have not gone well, when the engine is cold the power steering works perfectly but when it warms up the steering is hit or miss, one min its OK then the next its hard as hell to turn.
I have it booked into a garage on the 28th Sept for them to look at it, meanwhile i have bought a vacuum kit , i just need something to create a air tight seal on the reservoir and hopefully i can bleed it and check for air leaks before going to the garage
Looking at the fluid in the reservoir it does not seem to be flowing either. (poss air or this elusive one way valve)???
time will tell.

Hi Trev74.
What was your final outcome to this problem, or have you not solved it yet please let us know.

Unfortunately the landi is still in the garage. The pump has definitely gone now. The garage is waiting on their 3 rd rack as the first 2 have been damaged in transit.
I got them to buy an original pump Inc delivery for £ 516 .
I just don't want to take any chances.
But will keep posted.
