WD40 is a menace. It isn’t as good as oil to lubricate. It isn’t as good as Kroil for penetration, the only thing it is good for is if you spray a ton of it on the underside of your rig, when you get done mudding, the mud will come off with a pressure washer.
I knew a mechanic who would hold a butane lighter a short distance from the WD40 nozzle and use it to torch black widow spiders.
WD40 is good to get rid of water, but it sucks as a lubricant. Anything that stays wet attacks and dirt. Go to the bike shop and get some dry Teflon lube.
