I know this topic has been spoken about once, so apologies for bringing it back up, but the squeak leaf suspension i'm experiencing from my MQ GLS (about 12,000km old) is ridiculous...
It didn't do it at all until recently after a trip to Robe's Little Dip National Park. I gave it a big high-pressure wash afterwards to get rid of any residual sand/salt and sprayed the shit out of the leaf packs.
I'm going to head down to the local hardware store and get some WD40 and hope that does the trick.
Does everyone else experience my pain? Stock suspension i might add.
