Zerk Count

[SNY SD UP]

There was a thread on Zerks I was following, with some discussion on Zerk Count, which I believe ended up being '16', at least for the LE2.  While crawling around underneath, I was able to locate 12.  So I was looking for a diagram to show locations, but I believe a picture provided by John Davies, is a good substitute for a diagram.   

I just circled them in red on JD's picture, but did not number them, and I am now seeing 16.

I will go back to the Quonset to verify, but is this the number and location?

Correct, there are the 16 that you have circled.  The 4 (2 each) on the two EZflex couplers are very well hidden and hard to get to.  Removing the tires makes it a lot easier to reach those ones.

FC - Thanks for the confirmation.

We will be removing tires to do the bearing replacement (Timken's) & greasing.  While off, I will do a few more tasks in that area.

Oliver suggests this suspension be greased every 3000 miles or 3 months. 👍🏻

Here is a neat video on the EZE flex.

Cool video!👍

Thanks! I put the yellow caps on my jerk fittings a couple of days ago (along with brake shield dust caps), but only found 12. I'll crawl under there again and see if I can reach in to add the caps on the other four. Otherwise, I'm waiting until the first time I remove the wheels.

I appreciate the reminder!

I HIGHLY recommend that when doing brake/bearing service that you verify that the EzFlex "Heart Bolt" is torqued to spec.  Always put your torque wrench on the nut side as the bolt head has splines to keep it from turning.

We have documented four instances where for what ever reason, the bolt head splines were compromised and that allowed the EzFlex to spin the bolt and nut.  What happened then is that the nut walked away from the trailer and the bolt tried to follow.  Fortunately the bolts were hanging on by their last two threads.  Had these owner's trailer gone negative (Deep pot hole or catching air), the unloaded bolt likely would have flipped out.  Not something that you want to experience on the highway at speed.

Per BHNCB the center bolt nut should be torqued to 65-75 ft-lb.  Per OTT, the flank of the center bolt (NOT the threads) should have Never-Seize applied. 

If you find your center bolt nut not close to specification torque, you likely have compromised splines.  Apply say 50% of torque specification.  If it spins, remove and inspect. If you find your splines are damaged..... be glad you caught it. 

If so, see BackOBeyond's the forum post "Dexter axle loose bolt at the equalizer " and my June 9, 2022 fix.
