Hi guys,

As some may know I have a creaing from the front and a creaking from the rear.... and that's before I talk about the car 

Anyway, the creaking from the front has gone since me and Martin fitted new wishbones. But I still have the creaking from the rear. A session of prying everything looking for the source produced nothing. I was going to replace donut bushes even though they felt secure in place. But I think that's a mistake.

I did however discover a bit of oil on the shock body but I didn't think that would cause creaking. However, having spoken to my tutor he thinks that the shock leaking could simply mean that it's allowing other suspension components to contact each other; so even though the creaking isn't coming from the shocks... it's the thing that's causing it.

Does this sound plausable to you guys? Bearing in mind I've found nothing else of concern re the rear suspension?

Cheers boyos

Anyone? lol

If its leaking, it ought to be replaced. Regardless of anything else.

[Webby the Bear]

Cheers Chris. Yup, will replace it. But just wondered from a learning point of view if it could cause other suspension components to rub/touching .e. Causing the creaking

If there's no fluid in the shock, or not enough, quite possibly.

Cheers mate. As I can't find any rear suspension problems I'll swap these out and hope that clears the creaking 

How long was it since I saw you? 2011? I'm thinking that's a short life

Very short. What did we fit? Got the receipt?

Non self levelling shouldn't leak from the shock body, no matter what.

Sure its not running down from the seal?

Genuine GM. Non self levelling.

All I know is there,s a bunch of oil on the bottom as if it's run down from up top somewhere mate. That from the seal area?

Depends on the severity of the bump and the characteristics of the shock and spring. The spring carries all the weight, to the point where the shock could be completely removed in theory. Obviously you can't do it in practice on most cars because the shock governs the maximum extent to which the spring is allowed to extend.

A bump with a fierce edge will load the suspension more quickly than a bump that has a radiused edge. Without the shock absorber to check the movement it is possible the suspension could bottom out, on a harsh bump.
The whole relationship between damping and springs is deep to say the least.

Your shock itself could be creaking, nothing uncommon about that.

Thanks Andy . I'll get the buggers replaced ASAP

Seal is most likely. Might be worth looking into a warranty claim.

Cheers mate. That would be real handy. Sadly though I doubt I have the receipt 

Never mind... Live n learn.

Going to try pattern ones this time I think

If purchased on tc they might have a record...?

Hmmm. That would really help with the current dough situ actually. Thanks Chris

I've got a creaky rear too 

Likewise, a prybar doesn't reveal anything untoward, so I'm actually going to replace the rear axle mounting bushes (donuts) to see if that helps. I'll let you know how I get on.
