Or add new struts.

there is a problem with your ride control system could be nothing but a sensor or bad connection or the control module or motor.have it looked at by dealer if it worries you or you notice a difference in height of car front to back.

Hi you should be able to buy new ones or second hand from a wrecker however if all else fails try using a different year shocks as most subaru ones are the same like a 94 for example

possible air leak use soapy water and spay bottle to locate

You can replace the air ride system, with a conventional non air type,like on most vehicles

If your going to keep it another ten years,I would do that

If you decide to continue to diagnose and repair your system ,and you will, often, and hopefully never at a dealer,or it will be like a second mortgage payment

Strutmasters and other have replacement suspension for it.

Definitely sounds like there is a leak in your air suspension somewhere. I'd have a local shop check it out. There is a switch for the air suspension either underneath the glovebox right hand side of firewall. or in the back of the vehicle behind the left panel. it is labeled suspension

That all depends on if you have the comfort or the sport suspension. The sport is a bit stiffer, and the comfort is pretty floaty. Now, repair shops will tell you that you need to replace the shocks every 50,000 miles, however they should be good for at least 100,000 miles. But, how to tell. There are 3 items to check- how much "dive" does your front end have when you brake? If it is significant, then you might be due. The opposite is true when accelerating off the line. Finally, push down on the front and back end with your hands, and if it bounces straight up, then you should still be good on your shocks.

If you have rattles from the shocks, either the mounts or the shocks themselves might be bad. You want to replace the shocks in either case.

Note, that replacing the shocks on the X Type is extremely expensive.

Experienced problem after problem with my suspension on my 1990 LSC. Finally contacted "Strut Masters" online and replaced my entire system with a conversion for less than 400 and an afternoon. Installation was simple.

Leveling sensors froze up ? Have you been through snow & slush?
Can the vehicle be stored in heated garage for a night?
