How many people here had to replace rear bags? I thought someone had to swap 3 out of 4. I have only changed my front bags mainly because car was sagging on the front end from the beginning. Also thinking the front bags carry bigger loads and larger in size with more chances to have a weak spot. I realize now I might have to replace rear bags as well to be absolutely sure there are no leaky bags. Besides the fact my X now almost sitting on the rear fenders for a few weeks. Front end stays up ever since I swapped old bags for new once from Arnott. Rear once are cheaper @ 200 a pair, mainly labor. Should not be harder than the front. Anybody who had to update rear bags please let me know.
PS: thank you Weasel for very valuable info.
