Title: Rear Springs (with self-levelling)
Post by: viper on 27 January 2015, 18:24:12
Hello,

Sadly, I cannot find any aftermarket rear springs to fit my Omega Elite saloon.

The dealership wants £292 for a pair!

Every Trade supplier has informed me that they can no longer get aftermarket stock. The only option is the main dealer.

The BOGE part number is 25.E49.0 - No longer manufactured.

The aftermarket springs I have had before with reference CS23067 - No longer manufactured.

This is very serious as my omega is now becoming so expensive to maintain that I simply cannot afford to pay such ridiculous dealership prices!

The Dealership quoted me the GM part number: 9193197 .

Any help would be greatly appreciated.

Cheers :y

Andy

You dont need to have sl springs. I run my sl shocks with normal springs all it does is stiffen the back end up a bit. Kyb springs are one of the recommend ones. :y

Hi, don't know where you are but if that really is the case and you cant get them, then can I suggest you try a spring manufacturer directly.
Here in Sheffield there are at least 5 or 6 of them offering such a service. I had a set(4) made by springcoil.co.uk and I seem to remember they came in at around the £80 mark about 8yrs back. I also remember they said that they had most cars on file ready to go or can work from your old ones.
May be some near you if you Google.

Simon.

Sorry to dredge this one up, but I guess it makes sense not to have a zillion threads about the same thing.

I had to replace a rear spring on my Omega at the weekend, on the way home. Garage that did the work ordered one up, and naturally, it was a standard spring, not for self-levelling. We didn't have a lot of choice once the old one was out, so in it went, which means an imbalance across the axle - not ideal. I'll be ordering one for the other side in due course.

Thing is though, the cones each end are a loose fit on the new spring - the coils are not as tightly wound as the one that came off. Is this an issue? Can you get standard cones?

Here's the side-by-side comparison.

Is the spring loose in place?

Should have been replaced as a matched pair...

Spring doesn't move about with weight on it, and we know it's still got weight on it even at maximum extension. I know they should have been replaced as a pair, but by the time we realised that there was a mismatch, we couldn't get hold of another spring. I didn't realise one had been ordered before I actually arrived at the garage.

On the plus side, the handling does not seem to have been affected by the mismatch, but I will get it sorted out. Besides, if one spring has failed, the other may not be far behind it.

My Elite failed the mot a few years ago on a broken rear spring.I had both replaced with KYB springs.How things would fare with a S/L spring on one side and a standard spring on the other I don't know.Springs are one of the items I would always replace as a pair.It is surprising how many owners[not particularly Omega owners,but in general]just have one spring replaced-presumably for economy reasons.

To be honest, I'm not convinced it's always necessary to change springs in pairs. Dampers, definitely, but springs don't degrade in the same way. Uneven damping can be very uneven indeed. Even with different spring rates each side, mine doesn't feel unbalanced. However, I do want it to have the same rates each side, so will be looking to even it out.

I personally wouldn't do any suspension work (or brake work) on only one side.

Oh, but they do! I've just replaced the original front springs(187,000 miles, and the only part of the front suspension I hadn't replaced) on my car, and the front came up 30mm. Just doing one side would have been a very bad idea. And at £40(ish) for the pair, any cost saving is insignificant.




As for the OP's original question, even if the new springs are slightly looser on the cones, their tension once in place won't allow them to move. I put new stock estate springs on working self levelling suspension: it sits about 15mm higher than it did, and the compressor rarely cuts in. The back end of the car is noticably bettter planted, but the ride is still good.

Thanks Nick. I'll get another spring ordered up.

You should be... car will be fitted with self levelling shocks, which leave the factory with different springs to standard shocks.

At best, only fitting one is daft... at worst, downright dangerous.  :-X

I know! That's why I am ordering up another spring. That has never been in doubt. As explained, I didn't have much choice late on Friday afternoon when I was over 100 miles away from home. The car feels surprisingly stable despite the mismatch, but that doesn't mean I'm happy to leave it like that. It hasn't actually left the driveway since I got it home (good ol' fuel pump leak to sort out).

Not how your previous post read ;)

I would be replacing the pair, regardless of how new your new spring is... as you will most likely end up with a second spring that is no match for the first.

And before you say that it's easy to spend other peoples money...

Which I will wager cost less than half your one spring ::)

Sorry, I meant I'm not against the theory of changing only one spring if you're replacing with the same spec (though I'm thinking I shouldn't have said as much!). As I know I've got a mismatch, I do want a pair - getting the details from the garage tomorrow so I can order another one the same.

Those are what I bought. Together with the fronts they sell, I paid less than I was quoted for one rear spring locally.
