The steering pump on my 2010 Nissan E52 Elgrand (a JDM van) is leaking badly. This seems a not uncommon problem. Internet people say the usual cause is topping up with the wrong fluid. The O rings blow because they are very sensitive to the fluid viscosity. Other possibilities are loose connectors or whatever else can go wrong with steering pumps.
My choices are: try to fix it myself, with the help of this ker-ra-zy video https://youtu.be/44QuAJtDYIk
Or remove it and send it away for a rebuild for £2-300 and refit it. (This would only work if the problem is fixable with new O rings.) Or exchange it for a reconditioned one for £600. Or get a new one from Japan for £1100+.
The pump part no is 49110-1JA0B. I don't think any Nissan UK models have a similar one.
Anyone have any thoughts?
