Polybush what you can

Cheapy pattern bushes are best avoided as they are of intermittent quality, and polys easily outlast even genuine, yet cost about the same...

[Webby the Bear]

Cheers Taxi.... so you think my list of things i'm going to do is right? 

As said dont really know where to go after that

[chrisgixer]

Once again, sorry to post again regarding this but i am just trying to get myself a list of what i need to do to get the car riding tip top again. For some reason my slow brain is making this a bit of a mountain out of a molehill. 

Can i ask this first.... as i've mentioned i've been under the car and pried on everything. if a steering or a suspension component was bent would it be loose and immediately obvious when i started prying on components? Reason is cos i feel i've done all the checks i can as i've pried on everything and using this method the only thing i've found bad is the wish bone bushes.

prying finds play or movement or how much movement there is. A bent component can't be found this way, although If a joint has been over stressed due to impact then it's worth a visual exam of the surrounding parts.
 The most obvious sign of a bent steering or suspension part is in the steering. Is the steering wheel now off centre? Or in a different position than it was before at least? Does it pull where it didn't before? If it still drives the same as before I wouldn't worry too much as far as wishbones and track rods goes

when i take it to WIM (which i'm going to do after i've rectified this small vibration and the suspension creaking) i obviously want the car to be geo'd with all components healthy....otherwise i risk having to replace further parts and then paying for another alignment.

correct, although a wheel vibration won't affect the set up. Creaking, yes, you need to verify a part doesn't need replacing, or in the case of front ploys re-greasing, which involves removing the front wishbone bolt and affecting set up 

So below is what i plan to do and why.... can you let me know if there's anything else i can do....

looking at the 25-30mph vibration first...
1.) Recheck for wheel being buckled, outboard and inboard (i'm confident it's not this as i've checked them but i'm going to check and triple-check for good measure)
2.) Wheels re-balanced

I forget how the kerb was struck, but it's best to jack onto stands, get under the car and spin the wheels slowly and freely, while you see how true the rim, sidewall and tread run on both sides, run your hands along all surfaces looking for irregularities, look for stones, glass or nails in the tread while your there for anything that could force through and cause a puncture. ANYTHING out of round, dented, dinged, wobbly. A werp, sway or wiggle will give a vibration

Suspension creaks from rear and front...
1.) replace front wishbone bushes... there's definitely slop there and was an advisory on MOT anyway.
2.) replace ARB bushes... going to do these for good measure as they're easy and as a preventative measure
3.) replace donut bushes... as mentioned by chris these didnt give any play or movement at all (pushed on the rubber bumps) but the noise definitely went away when soaked in silicone spray. again not overly expensive and quite happy to replace them based on the testing and all other components were tight
4.) wheel alignment and steering geo at WIM.

all good

one final thing....is there any seperate checks on the steering i can do other than prying for looseness? as said i'm keen to not get to WIM and hand over £115 for them to set it up and some part of the steering is bent and have to then replace that and have another alignment done....OR can the alignment/steering geo still be done with a bent part as it will just have to compensate for it... i assume not but i thought i'd ask.

as above, it will compensate for anything that's bent but only if the settings can be reached and the component isn't bent too far. But as said these are very sensitive at the front, so if anything was bent you would notice through the feel and position of the steering wheel. You probably notice the imperfections in the road pulling the steering wheel out of your hands now, especially if there's a failed bush. The slightest movement in a pivot point or the road wheel compared to pre accident will show in the steering wheel position, or as a constant pull causing you to pull the car straight again. So imagine the effect a bent part would have on the steering, you'd feel it or see it in the steering wheel position

cheers boys. sorry for huge post but just feel i'm a bit outta my depth as i have little to no experience of these and it's such a critical and detailed part of the car

btw, mention omega owners and you get a discount in the price

[chrisgixer]

To add, re silicon spray, spray each component one at a time, to eliminate one by one.

Rear donuts replace with theses...

You might do the shocks and top mounts as well whilst it's in bits... ATP is as good a place as any, as their parts are ime more durable than Delphi/Firstline and they have good deals, two front struts are £85 for example

Get that list to Santa sharpish

[Webby the Bear]

Thanks for the detailed answer Chris and taxi for the links. very much appreciated! 

In terms of the steering wheel.....I think it's EVER SO slightly off but I do have to constantly move the wheel left and right to keep it straight. not moving it left and right like a mental case but it is noticeable.

I didn't mention this as I assumed it was just the alignment needed doing and that would get sorted at WIM.

So due to this is that pretty much confirmation that a part of the steering is bent? if so is it just a visual check that I can do for that? then what if I cant find anything bent?

I spoke to my teacher. He's convinced about the wheel or tyre being out of round. He's showed me how to check it again (I'm better looking at visuals) and to also measure between top of tire and strut and compare to the other side.... and to also measure between wheel arch (door side) and the tyre.... in the pursuit of confirming if somethings bent

what do you dudes think? if you think that's not right any ideas how I can get confirmation if somethings bent? or is the above mentioned steering constantly needing adjustment confirmation enough?

cheers lads

[05omegav6]

Could have tweaked one of the track rods, which is why I suggested the item I did, as they're effectively peanuts

Wheel wobble could also be a bit of bearing play... play does not automatically mean wear/noise though

[chrisgixer]

Constant adjustment implies play (or tyre wear or a set up issue). Easily attributable to a knackered bush.

There's nothing you've described that makes me think anything is bent.

[Webby the Bear]

Thanks Chris. And again thanks Taxi for all those links

Ok, ill simply replace the bushes and look more in depth at the wheels/tyres and see where we're at after.

IF the kerb bash did bend a steering or suspension component.... is it a case of just replacing that part and all will be well or will I have chassis problems i.e. it still being out of sync with new part ?

[05omegav6]

The moving bits are all designed to be replaced

[chrisgixer]

Thanks Chris. And again thanks Taxi for all those links

Wishbones shock and steering linkages will all require another set up if replaced if that's what you mean?

[Webby the Bear]

Thanks boys.

Today got to looking for this buckle.... and i had 4 others look with me. We're all in agreement that the O/S/F has a VERY slight out of roundness to the alloy. I'm thinking thats what is causing vibration, although drove car today and really didnt notice it at all.

i shall see what i can do about getting that wheel repaired.

Thats great. if they're all designed to be remved so they can be replaced then worst case scenario is i change everything  but i think after what you've both said that i'm going to experience a very different ride with these new wishbone bushes  (always touching wood of course  )

[chrisgixer]

So is this a wobble, like the steering wheel is being pulled left to right in your hands.

Or a vibration, like the steering column/front of the car has an up and down vibration.


...?

[chrisgixer]

Ps, they should be able to make it round again. Or replace might be cheaper?

Fit the spare, see if it goes.

[Webby the Bear]

It's two-fold Chris.... the steering wheel seems to vibrate in my hand at 30. Exactly like when a wheel weight is missing.... only nowhere near as harsh as that... it's barely noticeable but noticeable nonetheless.

And then i have the issue of having to move the steering wheel quite a bit to keep it straight. When i hit a pot hole its not ''wrenched'' out of my hand but sometimes, when ive caught the pot hole at a certain way, it'll pull one way... normally left as it feels like it goes with the camber after hitting the pot hole.

i get no ''wandering'' other than the above though
