So, maybe its the cold weather doing a number on old seals/o-rings, but my power steering (RHD D110) developed an inconsistent assist pattern over the past week.
Starts out a bit stiff (but still has some assist), then after 1/2 turn of the wheel the assist increases and then it becomes less again after another 1/2 turn or so.
The reservior is full and I didn't see any leaks along any of the lines and the pump appears fine (no squealing or other noises), so I'm focusing on the PS box itself.
Is there a wear item (o-ring kit, bushing kit or something) that can be replaced in-situ, or should I be looking for a replacement box?
did a search and found a thread within a thread on the box replacement in an older Tjfslaughter thread: http://forums.lr4x4.com/index.php?showtopic=16765
but that doesn't really help me diagnose the problem, only the replacement.
I would imagine it wouldn't be too hard to find a RHD steering box around with all of the conversions that have been done over the years, but I'd like to start with diagnosing it and perhaps refurbishing what I have first.
