Automatic self-levelling is standard on the seven-seat models. What model do you have?

The Nivomat system is self contained. It doesn't require an air compressor or electrical connection to work. The vehicle when you load it will sink down, but within a few metres it will return to the proper ride height. If your Suzuki XL7 is a 7 passenger version then the system is standard equipment.

    This answer (Solution 2) by emissionwiz is FALSE/INCORRECT. The question specifically asks about a Nivomat self-leveling system not some crappy air-shock system that this ignorant answer is referring to. Unless you are very familiar with the Nivomat suspension system, you cannot tell if it's on your vehicle just by eyeballing it. You must refer to the vehicle manufacturer's codes on the vehicle and then research what part of the code/number defines if if is equipped with Nivomats.

2010 E350 12K miles - every 10 seconds a hissing sound from under the hood after car is turned off for 10 minutes. What could that be?

It could be the suspension if you have the semi airmatic suspension equipped on the vehicle. It will level itself out to a certain height after the vehicle is turned off. Most of the time the wagons are equipped with a self leveling suspension at least for the rear. The pump and the filter where the air would release is in the right front underneath the headlight if i remember correctly

The rear suspension it has new struts and is equiped with air self leveling. but my drivers rear tire is leaning in bad

You will need an alignment. The strut is slotted to allow camber adjustment.If the tire is leaning in then the camber is excessively negative.

Can i replace my gas adjust with coil spings on my 94 volvo 960, they want $300.00 each plus $200 labor, there has to be a cheaper way, please help

If you have the self-leveling Nivomat rear suspension system, you can replace your Nivomat shock absorbers with standard shock absorbers. You also have to replace the coil springs with standard coil springs. Please note that a combination of standard springs and Nivomat shock absorbers, or Nivomat compatible springs and standard shock absorbers, will not work.

If it is just the cost of springs that you are concerned about, try purchasing your springs elsewhere, and having your local mechanic install them. Two good sources online are; and . You can find Nivomat compatible coil springs for less than $120 per pair.

00 ford expedition rear self leveling system

Try jacking up the vehicle and putting it on jack stands letting the suspension hang down. Disconnect the battery for a few minuts and reconnect it and it should inflate the airbags and level off the suspension.

My 1989 jag xj6. the rear suspension (shocks) are down

Hi Verbatum

Yes, replacing the self leveling rear shockers with gas shocks, is the way to go.

The self leveling system was notoriously problematic.

Due to either to the leveling sensor going faulty, and making the car go up and down, whilst sitting at the lights. ( Do not be surprised to see that yours has been disconnected. )
Other problems are loud knocks over the big bumps, and finally oil leaks from the shockers.

Yes Jaguar in there wisdom, did not make things easy, and new gas shockers will not match your old springs.

I do have all the Jaguar part numbers somewhere for this job, if you want to keep it all Jaguar.
( let me know and I will have a look !)

I have seen in the past, Modification Kits being offered in England, but would have to get back to you with source.

I see you are in Canada , and I am in Spain, and not familiar with your spares situation out there.

You will be requiring 2 Gas Shockers, 2 Springs and retaining collets, and plates.

I hope I have been of help.

Good Luck

Volvo 960 24v 3ltr auto estate

I have had the same symptom on my 1994' 960 (sedan).

I thought (told by the dealer) the shocks had worn out (although the car was only 110000 km !...), so I had the dealer change them (they had a promotion). It did not change much of anything, except it lifts a little bit more (about 1 cm more), but still "sags" after about 1/2 hour.
It takes about 1 km driving to pump back up.

I have never been observing that symptom on nivomat-equipped 940 wagons with solid rear axles, and knowing that 960 sedans (with multilink rear suspension) having nivomat wider (3.5") than rear solid axle wagons (940 and early 960) which are 2.5".

So, my interpretation is those wider ones support a great deal of the weight, even more that of 940 wagons, so they react differently by sagging more, due to internal micro-leaks.
Also, and consistently, springs with nivomats are thinner and they may also wear out faster than on standard supension, putting even more load on nivomats to compensate.

Therefore my conclusion was :
- It is not because of the shocks,
- It may be the springs
- It is not really a problem, is it ?

These are side products of the all wheel drive system, incombo with the locking rear dfferentials.

You'll find the auto-lockers will tend to do that following a tight turn, particularly when you're doing it quickly.

The thud is similar in nature; it's just the All wheel system trying to figure out where to put the power.
