Replaced my rearward wishbone bushes. No other changes, old ones not failed. Do I need set up?
Steering is still straight, no pull. Tram-lining is improved though, but still not quite happy. Summat not quite right, intend a tweak to the steering box tomorrow.
Anyway, wim? Or not?

Poll added.

If there's summat not quite right, then you already know the answer :y
-
what are your tyres like? ::) ::) ::)
<runs & hides!> ;D ;D

We know. ::)

I've never driven an Omega which doesn't wander. Some are much worse than others.
I didn't have the privilege to drive one off of the forecourt, so I don't know what they were like from new, but couple a big old chassis with quite large footprint tyres and it's going to be a task to make it 'true'.
If you take it to the likes of WIM and nothing needs adjusting, do you have to pay? :P
-
I knew when mine was off as it wandered. Severely.
Went to the WIM Open Day and mine was way out (ive still got the original results knockin' round somewhere).
As soon as they'd finished I jumped on the m1 and it was sorted. very pleased :)
I've heard it mentioned on here that tracking should frequently be checked/adjusted. but mine hasn't suffered any tracking probs at all since

I voted yes purely because I like spending other peoples money!! :)

You only put 'yes' and 'no', what if I don't care?

What's the poll say? I haven't voted, so can't see the results. ;D

About 3 months.

Edited :y

If we suggest that no Wim required if replacing forrard bush with poly and aft undisturbed ergo does that not suggest that if aft bush is disturbed then alignment is then needed?
???
-
Indeed it does :y hence my first...
But Chris knew that before he swapped the bushes out ::)
-
I voted no, on the basis that that it's been done 3 months ago, so presumably was correct then. You've replaced an OK bush with a newer OK bush. Importantly, the wishbones are the same, and the bushes were in good condition when it was WIM'ed. These are the factors that will put it out, IME, assuming it hasn't impacted a curb, in which case we'd be crying over a knackered alloy instead of a niggle. ;)

Same

Estimated time until next tyres?

I stand by my vote then :y if something feels amiss, you'll tolerate it for a bit, eventually getting it sorted and potentially needing tyres sooner as a direct result of living with it :-\
Might as well leave nowt to chance and get it checked over :y
-
Must admit, I fully intended set up before doing the work.
But during, I had my doubts. Non failed bush aside, the wishbone position was my concern when its bolted up again, which is actually quite accurately positioned.
The front poly bush is a very tight fit and dictates where the rear bush bolt position in its elongated hole....;
Front bush / bolts
for and aft important but fits tightly. Vertically I'd say least important.
Rear bush
For and aft set by front bush as said. Inboard out board, bolt heald tightly.
So the only concern is the play of the bolt in the bush holes.
1.5mm at worst?
Thing is the bush metal spacers have left a dent in the metal anyway, and I'm pretty sure they have centred themselves back in the same position.
So from the re fitting point of view I'm inclined to say no set up.
Yet its still not quite right.
-
I should add, it's improved. Just needs another 10% from somewhere.
-
What was the reason for changing them?
-
Tried rotating tyres front to back?
If you're convinced it's setup, take to somewhere where they charge per adjustment?
-

Tramlining. Vague steering.

9j rears. Won't fit the front. But tyre wear looks ok.
-
Hmm. That's a pain. I always put new tyres on the front, then rotate them to the rear when they start to tramline (which they do half way through their life with no visible wear issues.

you won't want them big ol tyres on soon,be time to fit the winter tyres on steel rims ;D
but that's another looooong thread ;D

ok , I'M trying to be helpful.. :y
sell the damn thing and get rid of the headache ;D

Last ones (Mo) didn't behave like this. Even wear on both fronts, both edges worn, middle with a fair bit of meat left. So all normal.
Straight as a die. Surprisingly. Hence I bought again. Something degraded somewhere.
-
Could the shoulder wear be tipping it over the edge :-\
-

No mate, the last set wore evenly equally on both edges. Didn't tramline.
These are only 3months old. There's no shoulder wear that I can see so far. Although there is some, obviously. Just nothing wrong. All looks fine. And yet....
-
Same tyres I presume :-\ different batch or a revised compound maybe...
-

Exact same model on the sidewall. Grip level seems same. Handling seemed same when first fitted. ...
...just checked my records. It was the rears fitted 3 months ago, fronts where fitted in May. So older than thought, but still not behaving as the previous same set now. :(
I don't think its tyres though tbh, as the new bushes saw an improvement. If it was tyres, or something other than the parts changed, I'd expect no change in handling.
Having said that, set up might account for the last 10% if that's degraded somehow in 3months...?
Steering idler is fine, although its the same as TB's one that lasted a year.
Bearings and ball joints all good.
Bushes fine, bolts tight.
Top mounts, I know the bearings are slightly pitted but they where when the car behaved.
Set up?
-
When you say 'bearings' do you mean wheel bearings :-\ they're quite sloppy at best, so possibly starting to wear :-\
If you're really can't put your finger on it, but positive that everything attached to the car is sound, that only leaves the geometry :-\

Yes, wheel bearings. No/fractional play. Fag :y
-
How old are the shocks :-\ though they would dramatically affect handling if failing...
Clutching at straws a bit, but you haven't done summat stupid like fill the petrol tank up when you normally leave it below a quarter :-\
-
Petrol? What's petrol? :-\
-
Petrol? What's petrol? :-\
::)
In that case, going back to your original question... Yes :'(
-
Having just voted, the pol suggests similar. Just ;D
-
;D
If it's any consolation, mine needs redoing thanks to a waterlogged pothole ::)
Might get the Mk4 bushes fitted, then get it done :-\
-
Wim yesterday.
Answer is most definitely YES! ,going by the front before figures on the left
Left ...camber -1.17 ,toe 0.11 ...set to, camber -1.14, toe 0.04
Right..camber -1,37 ,toe 0.21 ...set to, camber -1.15, toe 0,03
Must say, very pleased with the final figures. Good job wim. :y
-
That shows just how fussy the Omega is when it comes to setting the geometry...
Bet it now runs straighter than a very straight thing :y
-
Reassuring, knowing I may get away with slapping new wishbones on and WIMing it :)
-
I didn't say it was fixed. Btw. :(
-
Bugger :-\ are the symptoms improved?
-

Its tramlining less. So improved, and there's a gyro scopic feel from the steering. Starting to anoy me now.
-
Sussed it.
At some point the front wheels have swapped sides. Probably when they where re balanced.
Refitted to the same side as they where fitted when new, and it's behaving again.
Thanks f&@? For that. :)
-
:o :o Aren't your tyres directional? So were the tyres rolling the wrong way all that time?

No they're Asymmetrical(?), "outside" on the side wall.
I'm assuming there's uneven wear on the tyres, probably prior to the last set up where they got it cock on.
So say the camber is -1.20 left 1.10right "to counteract the road crown" as they call it, as the usual excuse for leaving it as is. ::)
The tyres then wear to those settings to an extent. Then the wheels are swapped to opposite sides. There's then an element of excess camber in the tyres tread that don't match the settings on the car.
Would that account for it? :-\ because sc3 are not directional tread pattern. So I guess that only leaves the pre existing wear already on the tread.
I did notice Micheldever where bet careful to mark which wheel went on which corner. Costco where not so thorough when they failed to rebalance the fronts. I only noticed the wheels where on the wrong side as one if centre caps was an odd one and was fitted pas side. I know that wheel was on the other side when new tyres where fitted.
Anyway, it's very much improved. Still pics up lines in the road but only just enough to be considered acceptable feedback in that it just lets you know it's there. It's more online with the life of the tyres now. Where as before they felt shagged reet oot.
Moral? If I'm right that is? :-\ always fit the same tyre back on the same corner.
-
Chris you are lucky ..directional or asymmetric tyres loose some of its braking power if fitted wrong.. :-\
-
If you rotate your tyres, they wil wear more e evenly,and you wont suffer from as much stagger.

Front to rear, yes (Although I think Chris has a different size on the rear) but not sure I'd rotate left to right. Most tyres for an Omega are directional, so this wouldn't be possible anyway.

As Kev says.
Fronts to rear no problem. Costco insisted they would only fit new tyres to the rear of a rear wheel drive car.
"Off you go then" says I. "See how far you get" ;D (Rears are 9j)
I know the correct thing to do is fit new to the rear. But I would never ordinarily consider swapping side to side, or rear to front, without expecting some odd feeling through the steering due to pre existing wear playing games (tram lining). Although if new(er) tyre was in better nick then maybe.
Luckily the only option on my particular car is to swap side to side, as the rears are bigger. So it was easily recoverable. After a while ::) got there in the end. :)
-
I would never fit new to the rear on an Omega purely because the first 50% of a tyre's life are the least prone to cause tramlining on the front, so that's where they get put. ;)
I don't agree that it's best to fit the most grippy tyres on the rear anyway. Power oversteer you can do something about. Understeer and poor braking performance (and even that only happens once the tyre is below legal levels IME) you are stuck with.

BTW, Chris, I think I have a voucher for eye tests at specsavers ... :P ;D

Oi! Is there a voucher that allows full reading of oof threads? Specifically the bit where it says "I didn't swap the wheels over, costco did" ! >:(
Although costco do their own glasses.... :-\
Bah. They're obviously shit then. ;D
