Leaky front axle

[whitetiger]

So tell us oh hallowed one, what keeps the upper and lower knuckle aligned? Last time I checked it was a kingpin and upper and lower bushings but then maybe you know better. I know, faith keeps them in place right?

Look it up yourself, you need the education apparently. The L series design is different than the M series but you think you are an expert on such things.

I don't know what is the design of L3430 front axle, but I recommend to take into account another possible reason of failure. In the below video, at the point of 1:29 take a look at a crack which may cause oil leak too.

My CK2610hst began leaking at the front axles. Upon looking at the dipstick I see it is vented (see the small hole on the side). Took the dipstick to my shop and used compressed air to try and blow out the crud that looked to be in this small hole. This popped off the top round disc that is pressed into the top of the dipstick, indicating there was no air flow thru the vent. Inside the dipstick there's a gray foam filter, which was jammed in there so tight it was preventing any flow. I removed the gray filter and after an oil refill I'm going to run it without the filter to ensure good flow. Remains to be seen if this is the cure... will update later. So, good idea Kioti for having a vented cap... bad technique for cramming an oversized filter in there to block all flow!

May just have some junk packed around seal. Clean it out.

Could it be that the filter allows plenty of flow to equalize the barometric and temperature pressure changes that the front axle sees? Those things don't change very fast or result in much volume. Compressed air is a whole different animal.
What else might cause a front axle leak?
