Light duty trucks hold 10 quarts and the C4500,5500,6500 hold 14-16 quarts.

NO!


If you give those zerks 1-2 pumps every 25k miles or so that would be way more then enough. I don't understand why people think you have to make grease bust through the boots before its got enough grease. Grease won't evaporate, it can't go anywhere so if you grease it once that grease will still be in there. The new ones don't even grease anymore. I've all but stopped greasing customer vehicles at work because 90% of the time the boots are already buldging or they busted.

i dont mean bust them dude, not an idiot. but its gotta be full. i see way to many trucks where they are completely empty. where does it go if there are no holes in it?

No they don't need to be full, not anywhere near it. If each of the grease zerks were given 2-3 pumps when brand new and never greased again they would last as long if not longer then the ones that get a douching of grease at each oil change. An idiot with a grease gun is a bad combination.

I thought they had the same Dmax? Do they just have bigger oil pans?

Its the same thing only different. Evidently the pan is quite a bit deeper. On the 2 ton chassis trucks the drain plug is at the front of the pan. Its actually a lot better as it doesn't splash and go everywhere when you pull the plug out. I hate dirty max oil changes though.

You are quite the idiot to think that 2 or 3 pumps from the factory will last the lifetime of the joint. Sounds to me like you and tools to work on these trucks is the bad combination..

Ford along with the Asian market has used greaseless joints for years and they rarely wear out. You get the guy that greases until the boots buldge and you go flexing the suspension and they start bursting. Then you get dirt in there and they go to hell. Have you ever seen how little grease is in a non greasable u joint? Enough to coat the rollers and thats about it and they last hundreds of thousands of miles. Wheel bearings with nothing more then a smear of grease last forever it seems.

then why the he!! am i changing ball joints on my dads sable at 50k? and my 99 F150 needed them at 65k. i only replaced the ball joints on my HD at 90K cause i was putting the lift on and figured i might as well but they could have gone longer. also, the boot on one of my lowers is torn but its holding up fine still cause im able to grease it every month or so.

Well you have the theory down, but not the real world practicality. Sealed wheel bearings, ball joints and tie rod ends frequently fail in less than 100,000 miles, at least on GM stuff. I can't speak for other mfg's because I don't work on anything but GM, but I have replaced a lot of the aforementioned items that had between 70K and 100K on them.

You are right about over greasing. Watch the boot, grease it until it starts to swell and stop. This may be one pump or several.

Precisely, I can count how many times we replaced greaseless joints on Fords/GMs at the shop I worked at. I would even go so far while the car was being serviced to use the needle on the grease gun and put some in these greaseless joints.

Well 10 quarts will be what your oil pan will hold, And for grease zerks. I change my oil every 8,000 miles. After I do that. I check my oil level in the differential and rear axle. Then each zerk I give it one pump of grease. I rather be a little low on grease then to much. To much grease can pry things apart like tie rods ends. So one pump is all I give them so they have something to work with. Some of the new chevy cars have no grease zerks at all. Which is nice maybe for a woman, But for me I worry if it's dry or there is something actually in there.

uh...lets not get carried away byes..!! we can all play in this sandpile.

Back to D,max oil capacity: Std pan is 10 Qts (litres). I ended up adding a FS2500 secondary oil filtrations set up to mine..it takes an extra litre and a hlf to fill the lines and filter. System uses a 2 uM filter cartridge. I typically do my OCI at 12,000km and the oil is in excellent shape. Takes 2-3000km to just turn dark.

for what it's worth.
cheers,
