So it turns out one of the rear air bags on my Discovery is leaking. Does anyone know what exact part I'd need for this and where online I can find one? I have a 2004 Discovery. I was looking around online at various parts but want to make sure I replace it with the right one. The dealership wants $677 for the part alone, not including labour, so I'm sure I can find it cheaper online. Thanks.

 

Most people from this forum go to Arnott for replacement bags and air suspension parts. Something you should consider though, is they will probably fail again in the future. Have you thought about just replacing them with coils?

 

Here you go:

Arnott Industries 1998-2004 Land Rover Discovery Air Spring Replacements - Lifetime Warranty

 

At $129 a piece, they are a great deal, better designed then the original OEM bags, less momey and a lifetime guarantee.
Make sure to replace both cause if one is leaking, the other is sure to soon.

 

Thanks so much for the advice. Since I'm not very 'mechanically' inclined when it comes to fixing vehicles, nor do I have the tools to do so, I'm going to buy the replacement air bags and have my mechanic install them. When replacing them do I need to replace the rear shock absorbers as well? I just can't believe the Land Rover dealership wants $677 per spring (not including installation) when you can buy them online for $141 from Arnott. Is it really that much of a mark-up from the dealer or are they installing something else when they do it??
