Title: AIR shock absorbers
Post by: fcc-pt on 05 December 2011, 23:45:40
Well, my omega b state rear shocks delivered their souls to the creator... in order to replace them, I have reached the official dealer! The genuine shocks are highly expensive thus I decide to look for other brands and replace them with LA361 Monroe Shocks. Well it seems that nobody knows if they are compatible with the air system equipment on the vehicle! What do you guys suggest?

No they are not compatable with the oe system.

But with a trade card, details below \/ vx self levelling shocks are £150! .... or pm andyc on here....? If that helps.

No, I'm not uk based...
What's a trade card anyway?

Only available in the UK (Im pretty sure) but Andyc will give you Trade card prices regardless.

Anyway, about the shocks are you really sure? Because all I can see connected at the shock is a air tube... ?
Why  isn't compatible?

Check:
http://www.taec.nl/monroe/
Fill make and model
and at the bottom of the page you can check the vehicle information...
I've talked with tenneco support and they are not sure :(
But in the online catalogue LA361 is mentioned for this vehicle! I'm really confused.

The ones i've seen work with a shrader valve in the boot and are pumped up by the hand/foot pump or what ever. So wont have the correct connectors on the cars air line. If you look at yours in the wheel arch by unclipping the connector from the shock you'll see.

I dare say something could be rigged up. But they are not designed for the gm connectors.

Why not pm andyc and compare prices first...? Postage will be the problem though i guess.

Thank you for the clarification... I'm sorry but I'm not familiar with the terms Retail, Trade and TC within the context. Could you please give an idea of how that works?
Title: Re: AIR shock absorbers
Post by: RobG on 06 December 2011, 13:56:08
Retail is the price that the general public will pay.
Trade is the price that a bona-fide motor business will pay. (lower than retail)
Trade Card (TC) is a lower price than both of the above. TC usually available by joining various car-related forums.

ohh k :)

So the prices are for each unit or the kit?
I'm not uk based can I get a TC?
Title: Re: AIR shock absorbers

You probably can if you send a message to 'andyc' on here; he's parts manager at a Vauxhall dealership and gives TC prices to anyone on OOF :)

I've done that but I'm wating for his reply... I guess I will have to wait then :)
Now I understand the mechanics ;) thank you all.

You can always replace the self-levellers with standard estate shocks, just pull the fuse that powers the pump

That would be a solution but I don't think I will make such a thing with my baby...
I will try to keep it Genuine as long as I can :)

Around £200 in total to get the shockers over to you then :'(

AFAIK Monroes are compatible with the self levelling suspension.

My shocks were passed it, so I had some Monroes fitted. There was aload of gubbins that came with them to allow the shocks to be pumped up (if fitted to non s/l cars), but my Monroes are connected to the s/l system

I guess we need to explane exactly how they are connected, so the op can replicate. For instance are all the relevant parts supplied by monroe? Or did an independant mechanic rig something up with parts unknown perhaps? Did you fit yourself?

Does Monroe supply all parts?
Do I need any special connectors or something else?
Did you installed the LA361?

This is getting very complicated...

Not really. Plug and play you have one choice if you wish to retain self levelling. Genuine GM self levelling shocks from a dealer only.

The monroes are not designed for omega specifically. They are intended to add self levelling to a car that has none, and is activated by an independant source, ie garage forcourt pump, footpump or whatever.... Unless Geof can show how they fit to the cars air lines, these are rwally intended for gls cd cdx or mv6 models that are not factory fitted with self levelling suspension.

Only Elite has self levelling. Yet your car is shown as mv6. Are you sure you have self levelling fitted first of all...?

I'm sure it's air dumpers and it has also an air compressor so I belive it does yes.

Mine is 2.0 "sport" and she has S/L shocks, so why couldn't your omega have it? I need need new shocks too but I'm considering an option to buy some used shocks with low mileage....the problem is they are very hard to find. :-\

Ok, generaly in uk only Elites have self levelling although there are exceptions.

So self levelling it is then. Next question, do you actually need self levelling? Do you carry much weight/load in the car? Because sl shocks are not very good dampers in my experience. You will get better suspension performance from mv6 shocks, however these will not cope as well with extra load obviously....?

self levelling shocks dont age well. Rust develops under the air bladders and eventually the oil leaks out, damping is lost and the wheel bangs and bounces over bumps. Used can be a false economy reguardless of mileage.
Retail in uk is £300 a pair.
But with a trade club card, or from andyc on here, they are £150 a pair plus delivery.

Just for the record and in view of me being in the same situation (Elite saloon with leaking rear dampers) I rang Monroe and they apologised that the (in my case LA360) load-levelling ones could not be coupled to the Vauxhall/Omega self-levelling system.

That being said, it can probably be done, it's just a matter of how much aggro it would take.  Hence the cost might be prohibitive.

As it is, the Monroe online shop say 180.66GBP with UK-only delivery.  This does not look like a price saving compared to Vauxhall TC price.

I really don't know why the mechanic said that I would have to replace the rear right side shock?

He claims that a good job would be replace both shocks!
When I look at the omega I can't see anything strange with the rear suspension...

Sometimes it might take a while till the air compressor stop but I don't know if it's due to malfunction.

I'm a bit afraid of replacing good shocks :(
In your opinion how can I test them?

I don't see any oil leaks beneath the rear.
Title: Re: AIR shock absorbers

Shouldn't I see something strange on the right side?
Title: Re: AIR shock absorbers
Post by: feeutfo on 07 December 2011, 12:17:10
It is always recomended to change suspension and brake parts in axle pairs. So be aware that uneven performance may result.

Support the weight of the car body with trolley jack,remove top nut and bottom bolt,unplug airpipe and remove shock.Replacement - the same in reverse. :y
Title: Re: AIR shock absorbers
Post by: fcc-pt on 16 December 2011, 14:15:11
Just this? No worries about the air circuit pressure? If I unplug the left shock air connector the right shock will not come down instantly?
Title: Re: AIR shock absorbers
Post by: albitz on 16 December 2011, 14:21:16
If the weight of the car is supported it wont matter if it does.The car cant go down with it.I dont think there is any air pressure when the engine isnt running anyway. ;)
Title: Re: AIR shock absorbers
Post by: Entwood on 16 December 2011, 14:31:58
Air is "trapped" in the system so will be released as the pipe is pulled, and is released from both sides at the same time.

Therefore, if the car is still supported by both the wheels, both suspensions WILL drop.... mind your arms/head

If the car is only supported on a single jack/stand on one side, the other side will drop. This could cause an unstable situation on the jack/stand and the car could fall off the jack/stand. BLOODY DANGEROUS. MIND YOUR WHOLE BODY

If the car is supported on stands, on both sides, as it should be, nothing will happen.  :)
Title: Re: AIR shock absorbers
Post by: albitz on 16 December 2011, 14:36:47
True enough. Axle stands will be the support of choice for the job. :y
Should have thought to mention stands in earlier post. :-[

Title: Re: AIR shock absorbers
Post by: Entwood on 16 December 2011, 14:43:14
For working on the rear I place axle stands on the "dishes" where the rear suspension doughnuts are bolted to the car. seems to be very stable that way and access to the wheel arch area is unimpeded.
