Dexter axle loose bolt at the equalizer


Recommended Posts

Over the past 3+ years I have been researching solutions to the "walk out" of the Ez-Flex Center Bolt due to failure of the "fixing" splines on the bolthead site.  This issue has occurred to at least three owners that I am aware of.  But first before spilling the beans on what I believe to be a permanent fix, have two administrative tasks:

  • First, I want to thank James Ussery and Mike who have been my sounding board for at least half a dozen half baked solution possibilities.  Each of those solutions were either not robust enough or would greatly impact "side of the road" repairs.  
  • Secondly, for legal reasons, the below solution is not currently endorsed by OTT or Dexter.

Ultimately I stumbled on to a product called a "Hex Head Capture Washer".  They are used by off road suspension modification shops to keep bolts from turning.   The cost of the washers was $1.31. 

I have installed two of them (one on each Center Bolt) and am totally confortable with this solution.

GJ, thanks for all of your effort in finding a solution here.  Would you please post a link to these HEX HEAD CAPTURE WASHERS as I'm sure others would like to buy them and apply the same fix to their trailers.   Thanks.

GJ,   CAPTURE WASHER or CAPTIVE WASHER?  Link would still be helpful so exact size that you bought that works and fits would remove any uncertainty.

I would be very reluctant to weld on that subframe, I bet the factory would not approve. it destroys the galvanizing and probably compromises the sealer between it and the aluminum frame. I don’t see any reason why one or two 1/4” stainless roll pins driven through holes in both washer and subframe would not work well.

Alternatively, weld a piece of steel 90 degree angle to the washer facing inward, to engage the bottom lip of that suspension hanger. That might be a simpler method, you could take the two washers to a local shop to be welded, then install them at your leisure after painting them.

Certainly.  At the below web site just scroll down to the 9/16" Hex Bolt for the size. They fit perfectly.

Concerning the HDG:  It has to be removed in the area of the Capture Washer only and about an inch further around the hex head capture washer. This extra space is to eliminate any HDG migration to the weld area.  Be sure to clean and re coat the weld as indicated above.  This will likely need to be re coated every 2 or 3 years as the zink  in the Cold Galvanize Spray Paint is sacrificial.

Concerning the worry about the tang rusting enough to fail:  I accept that risk as very minor compared to the damage that would be caused by having this critical bolt walking out as has happened at least four times that I was made aware of on our forum.

The word "only" was a mistake. See above.
