Hi, new to forum, and although I have made use of many of the interesting posts on here its high time I posted an appeal for help!
Basically a very long story short...
Bought an ex Mil defender 90 about a year ago had 2.5 na engine swapped for 200tdi and at same time secondhand power steering system fitted.
All well until it started cooling down late September when steering became stiff on cold start up. The colder the weather got the stiffer and longer it took to warm up and work properly.
The guy who did the work said it was probably the pump, so I bought and fitted myself a brand new bearmach one... No change the guy then said it must be the box ( 6 bolt) got exchange 6bolt recon box and drop arm from paddocks fitted that, still the same...
Replaced ujs on steering column... Still same except getting colder and worse!
Swapped fluid for fully synthetic ATF dextron lll level correct on cap dip stick..still same.
Brand new belt fitted and tensioned correctly.
System bled properly as far as I can work out, I have done it to the letter according to Haynes .
No kinks or leaks in lines.
Still same except now as its getting colder I'm also getting a chirruping noise on full lock!!
Tonight lifted front on axle stands and checked track rod end ball joints and seem fine, boots ok and no movement in them.
Also no leaks from ball hub thingy and oil levels correct.
Getting to end of tether...Help!
