Yesterday was a semi-nice day, so I decided to catch up on some
maintenance --oil and filter change (M1 the Puro 30001 sure works nice
on a 4.0!), TB cleaning, new Puro air filter, front-end lube, powerwash
engine and fenderwells, a quick run through the local car wash, the
usual. Work is slow right now and I'm bored.
I later decided to go the extra mile and do a 4-wheel tire rotation and
change out those el-cheapo OEM lug nuts with a good set of heavily
chromed, forged steel lugs. While I had one side up in the air doing
my thing, a neighbor commented on my practice of applying bearing
grease to the studs before torquing the nuts down to 90 ft/lbs.
He claims that it's a bad practice, and that the lugs will loosen over
time because of it. I politely disagreed, saying that it is the
friction between the tapered nut face and the wheel that keeps
everything tight rather than friction from fastener threadfaces, and
that the only real way to get good, accurate, consistant torque is to
put a TINY BIT of lubricant on the threads before reassembly.
I know this all sounds petty, but I'm wondering if anyone here has
heard of mishaps that were the direct result of 'lug nut greasin'? I
like knowing that the nuts will spin off easily many years later and
won't rust up, no matter how much muck I plow through. And I make sure
everything is cool to the touch before everthing gets tightened down
--all pretty common sense stuff IMO.
Am I offbase here? Admittedly, this is 'old-school' technology, but it
makes a lot of sense to me, much like 'priming' the engine after an oil
change before actually firing it up. (Yeah, I do that too; I
disconnect the crank sensor, then reset the MIL when I'm done.)
