X5 rear air suspension

2004 x5 4.4L with rear air suspension.

How common is it for the rear air bags to deflate?

It looks like after 2 days my rear tires well are bottomed out.

Is it time to change the air bags or is this common... Noticed it a few months ago...

The air bags inflat with in 2-3 minutes of the car starting... No error codes...

It's an easy job... Will set me back $200 for both sides... Wondering if I just noticed it or if it's common for them to leak down after 2 days..

My air compressor holds pressure for months!

Not common for an X5 to be saggin on top of it's rear wheels after 2 days. What's your mileage? Air springs (bags) don't last forever...just like conventional shocks. Have you checked out Arnotts for replacements? Find the 11 digit BMW part nbr for the air SPRINGS you have on your X5 (use one of the online part databases like www.realoem.com ) which makes it easy to select the correct aftermarket air springs on Arnott's website: https://www.arnottindustries.com/par...21_pid162.html

Thanks for confirming. I'll look up Arnott parts. They actually are located a few minutes from where I work. I have an 04 with 120k. So I guess it's time. I'm thinking a slow leak...

If I hit the unlock button I can hear the compressor kick on and inflat the bags....

What about front axles... I'm going back and forth on empi... Any experience with axles selection? Both outside boots are leaking... And one was just replaced last year... Is GKN worth the premium?

I won't use an EMPI axle and I wont touch anything from Autozone or the like. Most are re-manned in China and just rebooted and filled with grease. I will only use GKN/Loebro (which is the OEM).

They're three times the price, but I've never had an issue. I've heard of EMPI's failing in under 10,000 miles.

Thanks! How do you know if the axles need to be changed vs rebooted? Both axles have some play when if I grab them and shake them around.... 1 was replaced in '08 the other is original.

Just ordered the airbags... I have the standard suspension... Not the sports suspension. I got a deal on ebay! $169 for the 2. Brand new Arnotts.

Axles and axles seals next?

Installed the 2 Arnott air springs today. Took an hour and a half. I got a deal $168 for the pair. The mfg date was 10/30/13 for the pair so 2.5 months old air springs.... Pretty new. Hardest part of the install was removing the clip at the bottom of the air spring.... The old ones were a little cracked up but seemed to hold pressure.... Will see if the new ones sag....
