Play in drive shaft/diff.

• Page 1 of 1
I can rotate my offside hub by about a quarter of an inch, maybe a bit more, measured at the perimeter of the brake disc, before taking up the "slack" at the diff. There`s no play in the (Miller CV) driveshafts so, effectively, the diff. output shaft on that side can be rotated slightly without turning anything. Is this what is called "backlash"? Is this unacceptable? What is the cure if it`s not?

Hi Jim
I assume you got one wheel on the ground, hence fixed, and you're rocking the other one. If so try doing the same for the other side and you should find just the same effect.
I personally wouldn't have said this amount of backlash is excessive and if you're sure everything else is ok and the diff isn't excessivly noisy, I'd leave well alone. If I had the diff out of the car and on the bench then I might have a go at tightening things up a bit but I would go tearing things down just for this.

I agree with Andy. There could be wear in the differential (Planet) gears thrust washers also. So it might not all be 'backlash'. Not enough for a stripdown..
Is it quiet? Does it make any 'clonks' here n there?

Just to correct what I've written above. The last line should of course read "but I would not go tearing things down just for this."
Sorry about that
Andy
Not a problem. But you should be able to edit your post, rather than having to add a separate "errata" sheet.

Hi Jim
I would think the diff on my car has about the same amount of play in it as you're talking about. I noticed it when I changed to the CV driveshafts 2 or 3 weeks ago but I didn't actually take any measurements or notice if there was any differance one side to the other. As far as I'm concerened it been working fine up to now so it will stay as it is.
