My wife's '04 GX has leaking rear air bags. The dealer wants right around $1000 to replace them. I figure I can buy the bags from an online dealer and install them myself for substantially less.

Is there a DIY available or does someone have the instructions from an Alldata or service manual? I remember doing a search and someone mentioning there's a trick to installing them properly. Otherwise, it looks like a straightforward job. I've done similar suspension work in the past, but never specifically on a car with air bags.

Any tips or tricks would be well appreciated.
