Trying to figure out what the problem is with the 3.2 auto, this is only pulling away on left or right angles i.e roundabouts and junctions....the problem being that as I start to pull away, I get a fairly loud clicking and vibration from the rear end,IIRC this may have been dealt with a fair while ago,but a search didn't reveal anything..mileage is currently 102k. TIA :y

Diff issue?
Oil level OK? CV joints OK?
-
If it feels like a bad shock absorber on one side, then your LSD is worn out.
While driving it will engage en disengage and that feels like a bad shock.
-
The shocks are virtually brand new Bilstein B4's fitted nine months ago,so Im thinking it's got to be one or even both of the possibilities that Dr G has outlined. ::)
-
I am not saying that your shocks are bad, but it feels like it, but only if you have a LSD
If you have a normal diff, oil, bearings, to much play.

And then you get this
-
Once the car is under power,everything is normal except for the initial start off, diff is quiet...no whine or rumble. Will have to get the whole thing checked out. ::)
-
Might be worth changing the diff oil, adding the correct LSD additive, before doing anything more drastic.
-
Known issue once diff oil well used....yours could be 15yrs plus old..easy fix, drain old oil and replenish with correct oil and the little tube of gm friction modifier
-
Advice taken.....going up to Serek's place next Friday, CV joints check and diff oil change.....fingers crossed that will cure the problem :y
-
Might also be a dicky gearbox mount...
Easy enough to check and change if required :y
-
Cheers Al,I'll stick it on the list :y
-
In my experience of LSD's on the Omega, and I had a few now, is that they do thump, or a slight knock when pulling left or right out of a junction, does they noise get louder or quieter with the TC off.

Yep. Worth checking the centre propshaft support while you're under there too.
-
Will pass that on to Serek, I haven't driven the car with the traction control on....will give it a look tomorrow :y
-
Mine was doing this last year. Changed the oil (with correct LSD oil, of course), no more problems. Not a bad job to do.

the LSD is unlikely to kick in with the TC on, what car are we talking about here, Auto?, is tbis UK Ex Police 3.2. ?

Probably was on the original Oil, you where lucky, as normally in between leaving the Force and finding a Competent Owner, some Muppet from Vx or A N Other Garage stuffs normal diff oil in there which knackers up the clutch plate over time. ;) :y
