    I have read the owners manual and there is reference to chassis lubrication, but no mention of how often.

    I know that the NNBS trucks have ( 2 ) grease fittings, but how often does one lube them?

    Back in my quick lube days we greased the fittings every time the customer came in.

    the grease fittings require lube when the sealed boot is not filled. using the hand gun apply gease until the grease boot swells slightly...too much and it will blow...

    as long as there is grease in the boot its good.

    only use the lithium based greases ..these have been the best for me.

    Grabbing the hand gun and hitting the zerks is just something I do at every oil change, fresh oil, topped off grease, pull the plugs and check all the lubes for color, texture just for peace of mind, Its kind of like when I detail, grab the lithium, WD40 and a shop towel to hit the hinge and latch points.

    [h=2]Don't Spray It On:[/h] 1. Door hinges. Sure, WD-40 will stop the squeaking, but it also attracts dust and dirt. Over time, you'll end up with ugly black streaks on your hinges.
    2. Bike chains. WD-40 can cause dirt and dust to stick to a chain. Use bike-specific lubricants, which typically contain Teflon.
    3. Paintball guns. WD-40 can melt the seals in the guns.
    4. Locks. The spray can prematurely wear down the internal mechanisms, especially in the pin tumbler locks, in door locks and padlocks. Go for graphite powder.
    5. iPods and iPads. WD-40 won't repair the Home button on these devices. In fact, the spray can cause the plastic to break down on the cover, and if some gets inside the electronics, it can damage plastic parts inside.

    If properly filled from the factory, you should not worry about it for many miles! If you cannot determine this by not feeling pressure against the boot, add one hand squirt. One thing that was mentioned before, to much is "Worst Case" scenario!

    I am a firm believer in the good ole WD 40, and I did say, shop towel, everything in moderation, and dont allow build up, I also favor silicon sprays for quick lubes, carburator cleaning spray is a great hinge cleaner so I dont get a build up of dirty gunk, WD 40 has helped with a many wet distributor caps, awesome to pull the plug and spray the piston on a motor you are wintering over, I am prolly one of those people that tends to over clean, over service, and not just my vehicles, been called ocd guy more than once, all of your observations are correct Poncho62, but I am still an old school WD 40 guy. :happy:

    carb cleaner is for metal only . if the spray gets on paint/rubber/wiring it will eat it...

    using paint thinner[mineral spirits] is what I use to clean off any grease/oil/road tars with no damage. I use the low odor thinner...

    I also use this to clean engine/transmission/diff parts then blow down with air ...

    There is no way that I would spray WD-40 into a motor to let it sit all winter. I see that stuff turn to wax as it sits all the time. I would use a table spoon of 30 weight motor oil or something that was meant for the application like the sta-bil fogging oil and cylinder protectant. Sure, wd40 is good for somethings like a bandaid fix on a wet distributor cap.(until you can get a new one and fix it correctly. I see boats that guys winterize themselves all the time, It never fails that they spray the entire motor down with wd40. In the spring the stuff looks like wax and has collected so much dust that the motor needs to be power washed. I am also OCD when it comes to almost anything mechanical that I touch, So much so that I make sure that I am using the proper lubricants for the application. I have spray cans for hindges, cans for lock cylinders, cans of dri-glide to lubricate the window track, I have a can of wd40 somewhere, it is about 8 years old. Not saying that what you are doing does not work, heck if it does and it makes you happy more power to you.

    I hear what you are saying Pikey and J cat, there are a ton of special products out there for every tiny little thing, I am just an old school guy doing it like I have for 30 plus years, and it works for me. gumout , brake cleaner, wd 40, silicon lube, lithium grease, keep em serviced and keep em clean. Hey, I have a great idea, all you guys send me some of those new fang dangled cleaning and lube products, I will give them a test drive. lol. That would make for an awesome gift in one of the up and coming contest, one can always stand to win a big ole box of polish , cleaners, and lubes. ( Steve, I would not put any WD-40 in there if I were you,) lol.

    I welcome all the feedback and input, afterall, I am here to learn, differences and all, heck I might even try some of the next generation speciality stuff out there. I am going to need more shelves for stuff. :great:

    WD 40
    W_ water
    D= displacement
    40+ 40 attempts to get it right
    Good for removing residue from stickers, cleaning stubborn stains on metal-maybe-
    I use nothing but heavy duty oil, really thick and worked in on my locks, hinges.
    I only grease things when the boot gets low. If you over fill you can bust the rubber boot, just squeeze the boot with your hand.
    When working on my bikes, tractors, cars/trucks I use surgery gloves. Cleaning I use biodegradable cleaners. Read the labe before using.

    a specialty cleaner would be throttle body cleaner,MAF cleaner. these require the correct chemicals or you will damage the components.

    carb cleaner should not be used on these engines. silicone is great for body chrome and exterior protection from de ice chemicals BUT !!! do not spray this when the engine is running as this product will damage the O2 sensors.

    working in the transportation industry cleaning metal parts with rubber/plastics we used mineral spirits low odor paint thinner and effective safe cleaning for you and the parts.

    with the brake parts denatured alcohol..

    I never used brake cleaner on the brake pads . used soap spray to capture the dust and a brush . never had any seals damaged or leak ..solvents around these parts can be tricky.

    Lol, you are old school J-cat! I have not heard of anyone else using denatured alcohol in a long time. I have a bottle of it in my garage. Friends come over and always ask what it is for

    with the brake units used , the use of this de-natured alcohol did work well to avoid the dangers of damaging the sensitive brake sensors used and seals. spray cans of cleaner would be not very economical with the size of these ..

    I am talking about vehicles that would make are trucks look like toys..

    In auto shop my teacher decided to have me spend a semester rebuilding wheel cylinders, master cylinders, and calipers (honing, cleaning, replacing parts) I went thru tons of denatured alcohol.
