Hi Gents

I’m having hard time getting grease into king pins. Is it necessary to take weight off front end?
 
No, it really shouldn't make any difference. Have you been able to grease them in the past?
 
No shouldn't have to jack it up. Usually it is because the grease is old and dried up in the fittings. Screw them out and clean them and while you have them out check that the grease hole in the bushing is lined up with the fitting.

Ok thanks. Let me try taking off zests and cleaning.

Btw is there drawings showing all fittings to be greased. I checked owner manual and vanpelts site without finding.
 
While you're checking on the king pins, check to see if they are worn. I found that when I install new king pins and have them honed to fit, the steering and handling of the front end is greatly improved. It'd be worth the time and effort.

If you have an original owners manual, you will find a "lubrication and maintenance chart" in the center of the manual. Any part marked with an "A" indicates that it should be greased with pressure gun lubricant. All other points to be oiled or greased are depicted on this chart. Ford recommends this maintenance to be done each Fall and Spring.
 
Actually one should always take the weight off of the spindle pins when greasing. That isn't backyard mechanic advice but rather professional (schooled) advice.
 
I always jacked up a vehicle because I just thought it was easier to get them to take grease. Some times if I had a helper I would have them turn the steering wheel back and forth to get the grease all around the pin..... Mark
 
If old grease is dry you can warm up with a heat source. I had a old truck that most fittings would not take grease and a few minutes of the torch fixed them. You should try a heat gun first.

Kube, any input as to why there is an advantage?

I was taught that the side of the pin that was weighted against the bushing would not be easily lubricated. To avoid this possibility, simply removing the weight from the pin assured an even application of lubricant.
Now, away from my schooling and in to the real world... I'd witnessed numerous times, mostly the old Ford I-Beam trucks wherein the pins would wear seemingly prematurely. These were on client's vehicles that were in fact well maintained. The common denominator? Vehicles were lubricated with the weight on them.
 
have you ever herd of a grease pit. years ago when they were in use you drove the car over it & it was greased from below with all four wheels on the grond how quick we forget but then again a lot of you are young & never saw them
 
there are 2 reasons to raise vehicle 1 lifting the axle will take the weight off the thrust race and allow it to take grease correctly 2 raising the vehicle will take any side load off the upper and lower bushes ensuring that they are fully lubed not just on one side also [instructions from avon meritor worlds largest and longest manufacturer of beam and solid type axles ] They also recommend rotating from lock to lock while lubing

Very true. The point that Kube makes seems perfectly logical. The other side of the argument points to real life experience.

I worked in grease pits, and under the old Globe drive on hydraulic lifts.

The fact that that's the way we did it, does not change the fact that with no weight on the axle, the grease can better flow into all areas.

Let us know what worked.

Totally incorrect, all weight should be taken off front end when greasing the king pins ! I professionally maintained equipment for over 40 years.
