Diff play

(1/3) > >>

Disco 90 george:
Can anyone tell me how much play should be in the diff when you take the prop off.

I've just done the uj's on the front as i had a knocking when i put my foot down, it's still knocking and i found the drive plate the prop fits to has a lot of play in it. :shocked: Don't think it should have as much as it does.

Thanks Graham

The diff alone should have hardly any. However, there will be a little play in the shaft splines too. General wear in the various components can add up to quite a lot of rotational play in the diff flange.

I had huge amounts in the front diff, but when I took it out it was fine. All the play turned out to be CV joints!!

Disco 90 george:
Thanks for that, looks like i have more things to look at.

The list is getting longer.

Hi 666 George,

I have a 04 reg TD5 90, and had a few knocking sounds and things. Spoke to Ashcrofts (gearbox diff supremo's) and they recommended a chap to me. I went to see him and he looked at all my drive system and had a go.

He then told me that my rear ball joint had gone at that all else was normal including the play in diffs etc.

There is a lot more play than you would think to be good, knocks and noises are normal, due to lots of small bits of slack in many components.

That was his opinion and i am happy with that.

If you would like to compare yours to mine let me know as i am only up the road from you.

Andy

Disco 90 george:
Thanks for that Andy, i may take you up on that.
It sounds like something is loose in the drive system, it knocks once as you put your foot down and and it knocks again 2-3 seconds later. Like something is being pulled on of place and then droping back in place again.
