Title: Part no. ID for Air Shocks please anyone ?
Post by: Big_Al on 26 March 2011, 13:59:33
Hi guys,


               If anyone can access the EPC , could you help by giving me the part no. for air shocks to fit a 2000 (W reg.) 3.0  Facelift   Saloon.

I think there are 2 types Saloon & Estate. As my car is riding high at the rear , i am trying to eliminate that the Incorrect shocks have been fitted.

If both part No's can be supplied  I can match up to what is on the label  of mine

TIA ,     AL :y

Hi everyone,

Was given the part no's by Andy B (Thanks Andy)   but

They do not correspond to what is on the labels of my shocks.

being a PC dim-wit I can't post pictures on here :-[ :-[

But below is how the labels read:

                                                    [size=16]GM    [size=16]22245839

                                        9127829[/size]

                                        368135153

                                    13  07  09   08 17 .51[/size]

If anyone can help to find the part No. from this i would be grateful'

Could the part no. be somewhere else on the damper? although I have had a very good look . there are no other labels & can't see anything stamped.

Regards Al :y

I thought the level on a car with self levelling suspension was controlled by the level sensor :-/

The way I see it the wrong shock absorbers might cause a harsher or softer ride but wouldn't change the ride height.

The level sensor operates an air pump which inflates (or deflates) a bellows built into the damper to either extend or retract the overall length. That is how the ride height is controlled.

No bellows - no self levelling ..  :)

I fitted new self levelling dampers to my Elite last weekend (purchased from andyc  :)) so I am familiar with how they work.

My thought was that the OP may not have considered that the sensor (& air pump) will work to maintain the ride height regardless of what dampers are fitted.

Jury is still out if these shocks are infact self levelling.

I see it that way too.   But am trying to find out why the car is sitting high at the back.

Looking at all angles , so looking at what the difference is between the two types of self levelling shocks & the possibility that estate shocks are fitted in case to my saloon.  Anyone know what the difference is?

tomorrow am going to release the bottom shock bolts & see what height the car sits on springs only.  present height is 660mm front & 690mm rear.

OK. To avoid confusion.

Essex Big Al. Can you confirm that you have a plastic pipe going to the top of each damper?

Definatley self levelling   Small plastic pipe to each one held on by a small wire clip. Rubber "bellows" section in middle of each one.

Have already done the raise & lower test with lever detatched. Car raises up & down as switch is manually operated. Compressor at front under  wheelarch starts as required.  :y :y :y

 So carrying on from yesterday, released shocks from bottom bolt on both sides , gave back of car a good bounce about then measured.
The car sits even higher but without the shocks connected .

rear n/s is 705mm    O/s  715mm      Crazy ! ! :o :o :o :o :o

having a re-think on this now. :'( :'( :'( :'( :'( :'( :'( :'(

Intriguing !!!

Don't know if this helps or hinders ...  2001 3.2 Elite Saloon. New rear shockers 7000 miles ago. Engine running, self levelling pump "finished" its business ... :)

Measured at the wheel arch vertically through the centre of the wheel.

F N/S = 675 mm
F O/S = 665 mm
R N/S = 675 mm
R O/S = 685 mm

Now those figures look very like your original figures ...... so what makes you think it's sitting "high" ??


 ;) ;)

660mm at front which seems to be LSC  height

Where as std elite is 675 at front  (I think)

Should the front & back not the same then ?

It just looks ugly compared to the front. gap between the tyre top & the wheel arch.

Car is on 17 VX std alloys   & 235 x 45 x 17 tyres

What we need is someone to measure an MV6 to see what they sit at  all round & compare to Elite sizes :y :y :y :y

Anyone handy with a tape  ;D ;D ;D

What markings do you have on the springs? 'LA' perhaps?  :-/
Title: Re: Part no. ID for Air Shocks please anyone ?
Post by: Big_Al on 27 March 2011, 21:41:59
LA on one O/s     - nothing at all on n/s .   had a real good look

Front springs are paint marked   Orange /grey on top coil &  orange on coil below that.

Any clues in that?  :-/ :-/ :-/
Title: Re: Part no. ID for Air Shocks please anyone ?
Post by: Andy H on 27 March 2011, 21:56:53
Mine has LA on the rear (both sides) and IIRC so does chrisgixer.

I haven't measured the rear ride height but does look a bit high  :(
Title: Re: Part no. ID for Air Shocks please anyone ?
Post by: Andy H on 27 March 2011, 22:05:45
Another thought.

The rear semi trailing arms tend to wind up (or down?) due the torque reaction from the parking brake, possible aided by an auto box in park.

Did you have the hand brake off and the gearbox in neutral when you did your bounce test?
Title: Re: Part no. ID for Air Shocks please anyone ?
Post by: Big_Al on 28 March 2011, 07:49:03
  Ah!  Hand brake was off - but car was IN park. 

Am getting ground to wheelarch measurements from an MV6 today so at least we will know the difference between the two models .

will post results on here tonight, :y

Reply to Entwood:   Re measured my ground to wheelarch sizes again today just to make sure. from ground vertically through centre of wheel as follows

N/s front 660mm      

O/s front  660mm

N/s rear 690mm

O/s rear 690mm

just waiting for MV6 all round sizes to be confirmed by Oof member


Will post up when  I have them :y :y

Right then results of the MV6 measure up ! 8-) 8-)

Ground to Wheelarch vertically through wheel center on his own MV6 has been confirmed by Darth-Loo-Knee as: 670mm all round

My car just looks wrong the rear height being 690mm in comparison to the front (660mm) .

It does not sound like much but it looks quite "ugly" to me.

Gonna try & get a set of rear MV6 springs & try them.

Thanks all  for putting up with this  long drawn out issue & all of your good input in the replies.

But I think we may have the answer now . . . . . 
Wrong rear springs   ::) ::) ::) ::)

Thanks All             Big Al : :) :) :)

Well done that man for sticking with it and hopefully getting the answer to the problem.

Will await follow up of this thread, once the correct springs are fitted.

Sure the car will then sit level.
