advise on a vcu please

I guess this one has been covered somewhere but I have struggled to find the answer I'm looking for.
2003 td4 manual 116000miles history unknown I did the vcu test with good results how ever when I reverse or creep forward on full lock it feels like the brakes are binding, I have checked the brakes there are all good no binding there. I have suspected the prop bearings were on there way out for some time but today popped out and heard a bearing noise being an mechanical engineer I know the noise means no good, so later today stripped the prop off and sure enough the rear prop bearing in us. I took the car out what a difference no binding on full lock. my question is with a good vcu would expect there to be some resistance on full lock or as I suspect is the vcu on its way out.
Are the recon vcu's from bell engineering any good?
cheers for your thoughts on this one guys.

I've heard good things about bell. I got a recon one froma local specialist and it seems fine.
another thing to check for with the VCU is drive for 15-20 mins and if it gets hot.. it's under stress.. now when i say hot, it's normal for it to be touch warm.. too hot to touch, id check your tyres are matched

Theres also alot of people who say to avoid damamging diff/ird then change the vcu about every 70,000 miles.

does that help?

Hi
With a good or new vcu in my experience there there is always a
detectable amount of resistance on full lock in reverse in neutral.
it is as if the hand brake is slightly on.Hope this helps
