A worn wheel bearing? - Check uneven wear on the threads for this. If you hit a kirb or a hole in the road - the nudge could put a bearing over the ridge of being ok or not depending on its age/use.
Thats what Hessy had so i changed it. Have a look if ther is any grease being split or a wet joint at the hub.

Prior to this i changed steering rack boots, strut rubbers and most lately the struts - it all has a significant effect on the handling.

Thanks Hessy, Taylor and Mad, some things to check then when I get home. Am in Kilarney at the mo so suspension is taking a hiding.

Brake reaction arm bushes, or bottom suspension arm inner bush.

Thanks Tristan. Drove home today from Killarney to Kildare. The pull is constant, drifting to the left once steering is let go. Braking does not make it worse and the hub was not warm at all on arrival in Kildare, Will jack it up tomorrow and see if there is any noise or rock from the bearing. I had to have the valve stem replaced on the tyre while in Bantry because I felt the tyre pressure may have been low as it appeared wollowy on the left and the valve stem leaked when pushed from the side. The new stem was fitted and the tyre held pressure. The bushings may be gone on the suspension Tristan. I will have a look tomorrow and see if I can recognise it.

Any photos where these are on her?

Could not leave it alone and so jacked it up last night.
I rocked both wheels horizontally and vertically. There is a minute amount of play in the left side but none in the right.
Span both wheels but heard no bearing noise and they moved freely.
The steering box had immediate take up from the movement of the left wheel by hand and the track rod arm transferred that directly to the right which was still on the ground.
The link bar from the steering box arm to the steering lever arm (front LHS) is firm but smooth when rotated about its ball joints.
The long track rod which links the steering lever arms from LH wheel to RH wheel is notchy and has audible thumping from the ball joints when rotated about its axis. The anti-roll bar drop links look good but I can see what I think is wear around the bushes which mount the anti roll bar to the rear side of the axle.

Good Vids Cheers - she is different from my own underneath.
Tristan will be able to identify the issue - no problem

Ah. That's not a Ducato!
@Hessy , the brake reaction arm is the one going forward to the lower front crossmember front the suspension arm.

No! Hymer Merc 2.9. Im going to whip off the track rod arm and replace the joints. Ill have to inspect the track rod for straight aswell. I hit a pothole in Dingle. It was a big one. There was a dolphin swimming in it.
