Jim Mason Posted April 29, 2022 Share Posted April 29, 2022 Ok got the Discovery 1 - 300 Tdi finally moving after 8 months - full engine change etc Clutch issues finally resolved but steering is solid. How can i bleed power steering as all pipes were renoved fluid topped up but level not changed. Where is the bleed screw located? Quote Link to comment Share on other sites More sharing options...
Snagger Posted April 29, 2022 Share Posted April 29, 2022 It’s on the top of the steering box. Bleed it with the engine off first. Then start up and exercise the steering from lock to lock, opening the bleed at each end until it runs without bubbles. Quote Link to comment Share on other sites More sharing options...
Jim Mason Posted April 30, 2022 Author Share Posted April 30, 2022 Tried that - put will try again - got fluid but steering is still very heavy to move. Unable to see any fluid movement inside reservoir. Has pump failed? Quote Link to comment Share on other sites More sharing options...
western Posted April 30, 2022 Share Posted April 30, 2022 Jack the front wheels off the floor, also the lower column UJ's might be worth lubricating to free them up. Quote Link to comment Share on other sites More sharing options...

What he said - but not for the same reason 🙂. It can be difficult to purge all the air out of the box. Bleed it via the screw on top with the engine off as has been suggested. Then work the steering back & forth, lock to lock (much easier with the axle jacked up) with the engine running. This will gradually push the air out of the pistons in the box. Also, Ralph is correct, it's worth lubricating the steering UJ's as they seize up. If still no joy, look at the steering pump. You can get an idea if it's working by loosening the bleed screw with the engine running. If it makes loads of mess, the pump is pumping at least.

Jim Mason Posted May 2, 2022 Author Share Posted May 2, 2022 (edited) 20220502_160405.mp4 On axle stands engine running can move wheels full lock left & full lock right with a single hand movement. On the road i am unable to steer without a lot of force. Edited May 2, 2022 by Jim Mason Added video Quote Link to comment Share on other sites More sharing options...
Snagger Posted May 3, 2022 Share Posted May 3, 2022 It could be the pump, but could also be an internal leak in the box, a collapsed bearing in the column, a seized CV joint or swivel bearing…. If you get decent flow from the bleed nipple with the engine running, then it is less likely to be the pump, but not impossible. It could be that the pressure relief valve is faulty, so the pump is producing flow but at too low a pressure. Quote Link to comment Share on other sites More sharing options...
Jim Mason Posted May 8, 2022 Author Share Posted May 8, 2022 All sorted, power steering pump had failed - replaced pump - all sorted now - drives like a dream Quote Link to comment Share on other sites More sharing options...
steve b Posted May 8, 2022 Share Posted May 8, 2022 If you ever have occasion to pull the engine again , just take the pump and mounting plate off the engine complete and let it hang , then the system stays full. Good you got it sorted all round Steve Quote Link to comment Share on other sites More sharing options...
