Judder when reversing on full lock

[Scoobasteve]

First of all Merry Christmas to everyone.

Been driving about over Christmas and while manouvring around I've noticed that I get a strange type of wheel judder when reversing on full lock. It almost feels like the tyres coming off the rim...

I've checked the tyre and all's okay, normal driving is fine and there is no pull to either side.

I've had the DCCD set to 'auto'.

Any ideas anyone?

Cheers

Sounds like what you get when the diff is NOT on auto at slow speeds

Try again with diff reset off then back onto auto-may reset itself

If its the same Id say you possibly have a diff problem/is it the same sensation as when you try it with the diff is off the auto setting?

Oho... It's broken.

Apparently this is normal and a behaviour of LSD.

The cars in next week anyway for the 30K so i'll get and checked and will post the outcome.

Cheers guys

Not on ours it ain't

Agree with Spike on the fact if you using the DCCD when travelling slow on full lock, but not on auto

Hei, I haven't been on since quite a few days. I need to get back into it.

Marky Mark or Ant have any ideas ?

Mine sure never made such noise. Only noise it made on full lock were the studs of the tyres scraping the inside of the wheelarches (wintertyres were a bit too high)

Did yours have the DCCD?

[The Swede]

No, why ?

All jokes apart. Is there a reason why the DCCD has more chance of getting stuck with a locked diff where the normal car doesn't ?

In the end, the diffs are mechanically about the same and lock for the same reasons: difference in rotation between left and right or front and rear wheels.
The DCCD should only manage the starting power distribution, if I am not mistaken.

I thought the DCCD came with a warning not to reverse with the diff locked?

[WR 1mposter]

DCCD allows you to distribute the ratio of traction depending on the severity of conditons, but any one who put the diff in lock position on tarmac

Mine also does this occasionally in the auto mode, my old 02 STI also did it and that didn't have a DCCD
Best get it checked out before the warranty runs out

Done this reversing full lock up a hill round a bend and it still did'nt happen!
