Finally managed to sort out my vibrations.
I fitted two brand new steel wheels to the rear of the car, with brand new tyres on. All balanecd up.
Went for a drive - smooth as silk. So the issue was with either the old alloys, or tyres.
Took the 2 suspect alloys to ETB today, they removed the tyres, and found that one alloy was slightly buckled (but only slightly).
Fitted two new tyres, (225/55/16), and very carefully balanced the wheels for me at lots of different speeds.
Put them back on the car - drove down the dual carraigeway back to work - vibration remains gone.
Fingers crossed :-X ;D
-
Fingers crossed indeed!!
I had a vibration on mine, from about 65mph. I took it to have the wheels balanced, and the rear wheel on the drivers side was out by 50g! :o
-
Fingers crossed indeed!
I will be doing mine soon so hopefully will be able to report back same.
-
Good News! :y
Just keep an eye out on eBay for a cheap replacement for next time!
-
Is this a facelift CDX by any chance...? I wouldn't mind a spare 7-spoke wheel (not a buckled one, obviously), so if somehow one becomes redundant and you wish to convert it to a (very) tiny amount of cash, then..... :)
-
I think you may end up having to replace buckled wheel, as its almost impossible to 'balance' that out...
-

Apparently buckle was very slight.
There is now NO vibratrion at any speed.
Still replace?

If the vibration returns, I would replace. If you are happy for now, stick with it, but keep an eye on strange tyre wear.

Cheers Jaime, I'll keep an eye
He did say the buckle was next to nothing, and he was a bit of a monkey, so seeing as the vibrations are gone, I'll see how it goes :)
-
I'm afraid that, now I've fixed this, and paid £110 for 2 new tyres, I'm going to have to charge you £50, if you want the car...
-
Quick Jaime.... he'll want even more when it's got a shiny new exhaust!!!

£45 for cash, but only if you valet it!
;D

OK... just got myself 4 new Michelins, Primacy HP (hew tyre that supposed to last longer or something), cost was 491.00 after some haggling inc. VAT, valves, fitting, balancing, environmental discharge, blah blah... which isn't too bad considering that I paid £600 for the four Contis three years ago... I know the Michelins can be had for less on the Internet (and also at Cosco) but still it is not so bad considering it was at a national chain outlet (ATS) and that these are London prices... why Michelin? because I needed tyres and that's what they had... not that I was unhappy with the Contis mind you. I will let you know if this actually resolved my vibration problems, but even if it didn't the Contis were down to 3mm so needed a change anyway.
-
Quite like Michelins myself.

No problem, you can have mine in three years time... ;D

Pirmary HPs are second best for Michelin after Pilot sport.But considering frequent rains in England its a better for your road conditions :y

Hello and welcome to the best Omega Forum on the Net ;D ;D

OK... just got myself 4 new Michelins, Primacy HP (hew tyre that supposed to last longer or something)
If you're eagle eyed or just really neardy like me, you'll notice in the 2003 omega brochure that the 225/55/16's are originally specced with Michelin HP's. :) I'd want some slightly better 'Pilot Primacy's' for that sort of money though :-/

Well the HPs fit the bill as they meet all of my requirements for a tyre: they are round, black, and made of the rubbery stuff! ;D

Slight hijack...
When the car was at ATS with its wheels off, I spotted one of the posters on the wall saying 'Brake fluid change - £35'. As I am getting old and lazy, and the car needs a fluid change, I though I'd ask them to do it before the wheels go back on. Quick and easy job. It sort of seemed to make sense... below is the conversation I had with the tyre fitter, and this is real:
Me: ...and while you are at it, can you also do a brake fluid change please?
Fitter: Sorry Sir, we don't do brake fluid change.
Me: ...but the poster in reception says 'Brake fluid change - £35'?
Fitter: Oh yes Sir, but we only do this as part of the complete braking system inspection. This is because if we change the fluid then the pressure in the system will be much higher, and if you have some problem with the braking system and we change the fluid without checking it first, then the high pressure of the new fluid will burst the seals on the master cylinder and you will have no brakes.'
Me: OK.... and how much is the 'complete braking system inspection'?
Fitter: It is free if there is anything that need to be done, otherwise if nothing is found wrong it is £30.
Me: so how exactly does this work then?
Fitter: Well the inspection costs £30, but if any work is needed then the £30 will be credited against the cost of the work.
Me: OK... so if I understand correctly, then the 'complete braking system inspection' will cost me £30, and then you will be able to proceed and change the brake fluid for £35 and refund the original £30?
Fitter: That's right Sir.
Me: This is fine then. So can you now please change the brake fluid for £35? I am quite happy for you to do the 'complete braking system inspection' beforehand.
Fitter: No Sir, we don't do brake fluid change.
Me: But you just said....
Fitter: I'm sorry Sir, but you really have to talk to the Service Manager about this.
At which point I went back to the reception area and waited for around 15 minutes for the Service Manager who was conveniently unavailable, and by which time the wheels were back on the car with the new tyres fitted so I just paid and drove off.
That was on Wednesday. On Friday, I decided to take the family car, the Previa, to have an oil change at same ATS outlet who are conveniently located near my office. I was originally going to do this myself, and already prepared the oil (bought on TC's 4 for 3 offer) and the filter (Halfords), but as I have a backlog of things I want to get done on the Omega (and as said I am getting old and lazy) I decided to let ATS do this for £40.
And since the Previa could also benefit from a brake fluid change, I was hoping that if I manage to find a more cooperative member of staff I might actually get it done this time. Unfortunately the reception was manned by the same tyre fitter from two days ago who oddly did not seem to remember me.
I booked the car in for the oil change and asked again for the brake fluid change, and the conversation was largely a repeat of the one we had two days before (and which he seemed to have completely erased from his memory). When I finally popped the question, will they then change the brake fluid, the tyre fitter said 'No, we wouldn't get involved in anything like that'. But this time he also added that the reason they wouldn't change the fluid even if they did run a 'complete braking system inspection' was that they did not have the equipment to test the master cylinder and ensure it will withstand the 'high pressures' of the new fluid.... However events took a positive turn (or so I thought) when some bloke with black oily hands stepped in behind the counter, and the tyre fitter sighed a sigh of relief suggesting this guy was their top mechanic or something similar.
The mechanic said categorically 'can't do brake fluid change, we don't have the pressure bleeder'.
Me: I see... well that explains it I guess. I suppose doing it manually would just take too long?
Mechanic: No, it is not a question of time, if we do it manually we could damage the braking system.
Me: Damage? how so? you mean reverse the seals?
Mechanic: Yeah, something like that.
And that was the end of it.... had the oil and filter changed though, so it was not a complete waste of time.
-
I finally got the chance to try the car on the Motorway with the new tyres. Made no difference to the vibration.... very very mild vibration at speed, and slightly more pronounced one when braking hard from 70 to 50.
When the new tyres were fitted, I asked the tyre fitter to check the wheels for buckling or other damage, he said no problem all rims seemed good and balanced fine, and though he did have to use a 70g weight on one of the rears he said it was slightly high but not unusual.
:(
-
70 g.. :o
Necessary turning the tire around the wheel and if it insists for more then 15-20 g the rim needs special interest I think.
-
Sounds like the vibration might be brake disks perhaps?
I'm quite amused by the brake fluid saga though!
I wouldn't let anyone touch my brakes after that explanation! New fluid being at a higher pressure? Muscling up to the seals and blowing them? Shows they could no more work on a braking system safely than perform brain surgery.

New Vx discs and pad fitted in April when I also changed the front wheel bearings. This was done following a serious vibration when braking problem, and initially cured it completely, but 6 months later the problem seem to be alowly creeping in again... :(
Mind you, it is not that bad and the car does not feel unsafe in anyway even at speed, but I just know it shouldn't be there...
-
after a drive down the motorway not too long ago i think i may need new discs, but it's VERY minor vibrations only when braking at high speed, or sharp braking at lower speed
-
Hmm. Could be that something's causing the disks to build up friction in one spot. Very slightly out-of round hub or wheel, maybe disk not seated absolutely flat against the hub? (get a DTI and see if there's any sign of runout) Heavy braking followed by sitting with foot still on pedal?

-
Just changed from 225/55/16 primacys myself, very good tyres and i had 40.000 out of the rears, 20.000 on the front. great in the wet and gives confidence that they wont let go if pushed hard. :y
Got pirelli p7's on now, so i will see how they perform .

Judder can also be caused by incorrect brake bedding in procedures, as the transfer layer may not be evenely spread, and/or cementite formation....

Ouch... a bit too late now. I was going to change the tyres and the idea was to keep one of the old 225/55s as spare on a proper alloy wheel instead of the 195/65 I currently have. But I since replaced the tyres and did not keep one of the old 225/55s, so I have nothing to put on the alloy wheel now.... I will probably kick myself for not buying it if one of the wheels gets buckled though...

Everything is possible... what baffles me is that the vibration was completely cured with the new bearing sand discs, and you wouldn't expect this to happen if this was a suspension component. So I have no idea why the vibration came back after 6 months, and I can't imagine that I managed to wear the new bearings/disks/pads (all original Vx stuff) in such a short space of time.
