so what should the temp be outside to get the best results for pumping the grease into the zerks.

It was FREEZING when I tried to lube my bearings and only 3 of the 4 took grease. I hit the stuck one at our first rest stop and it took it just fine then.

I just took off the grease caps on my 2008 Shamrock and confused by what I found. Only one spindle had a zerk fitting that was sheared off, I had to insert a small flathead to unscrew what was still inside. The other three spindles had no threads I could see and appeared to only go in .25" where the zerk fitting should be. Very strange since I was expecting 4 functioning zerk fittings. What should my next step be?

can you take a picture of this so we can make a better answer for you

make sure you have Al Ko axles - you say grease caps - are they silver / metal covers? or are they rubber covers?

If they are metal covers you may need to install say like Bearing Buddies which are spring loaded and have zirk fittings to allow you to pump grease into the bearing.

Not knowing exactly what you are looking at this would be my answer

they were silver metal covers, not the ones with the rubber sections. There were no zerk fittings anywhere else so I assumed they would be on the spindle. why would only one spindle out of four have a zerk fitting? poor manufacturing standards or possible repair?

if they had metal cover's then they are probably not the syle in this thread (Al Ko Axles)
If the Zirk fitting is on the spindle then those are the kind you would find on a Utility or Boat trailer from what I have seen.
some axles had a single zirk fitting in the spindle and greased both sides.

A few years back I had to replace both axles on a utility trailer and it had a zirk fitting on one side and not the other - I removed the zirk fitting and installed Bearing Buddies and got the covers for the bearing buddies and called it done which is what I would suggest you should do after you clean out the old grease and re-pack new grease into those bearing and install new seals. If the races for the bearing have any scoring they will need to be replaced as well or new hub's if you do not have the tool to remove and install new races.

Crawl under the trailer and note the axle ID tags. That will give you the manufacturer and the axel part number. If they are AL-KO axles, then I would suggest you contact their customer service dept. for an explanation.

a point i will make abt the proper grease. both seals on one side were leaking. believe i pumped a general purpose (incorect drop pt temp) into both of them abt a yr ago. in both of these, the grease was almost liquid (that that closest to the rear bearing). that nearer the outside bearing was fine (proper grease).
by the time i had gone to the other side, i had changed to the proper grease. one seal was fine the other was leaking some...that is aslo the seal that had been disturbed last year to do brake repairs. seal was good at that time. haven't been into anything sense bought in 2002.
i now know why they (manufacturer) doesn't want u to mix grease.

in looking at how the grease is inserted into the ez lube axels and how the buddy bearing works, it appears the buddy bearing would do more than keep pressure on the hub and keep water out. the ez lube allows u to push the old grease from the back out the front...changing it out.

Al-ko axles bearing adjustment>

1. To get a proper "feel" for bearing clearance, the spindle nut must turn freely on the spindle and the brake must be readjusted so that there is no drag on the drum.

2. While slowly turning the hub/drum tighten the spindle nut to approximately 20 ft/lbs then loosen. This is especially important if new bearing races have been installed.

3. With drum stationary (do not rotate), re-tighten the spindle nut to 7 ft/lbs (zero clearance) then back off one slot (0.001"-0.010" end play) align the cotter pin hole. Insert cotter pin and bend both ends over end of spindle. Install grease cap.

This is quoted from the 2,000-7,000 lbs AL-KO owners manual, page # 23.
