My link plates keep moving out of vertical no matter how I tighten them. There is also serious abrasion where the bars hit the link plates. In addition the both "L" retaining mechanism have bent on both sides. (The manual says to just switch sides to "increase positive contact".) Okay.

Are others experiencing this?
Hi,

We had a similar experience with our '21 we picked up last month.

ETI installed/configured the E2E for us when we picked up the trailer, and it had squeals, groans and disconcerting "pops" on turns.

First night out camping we have, I think, a user(me) error, and the hitch coupling latch is somehow bent(too much downward pressure trying to latch it?), so we head back to ETI to have it fixed, as it now won't completely close on the ball, making us, as you'd expect, very, very nervous towing, being complete novices(although a guy we hired to come out to look at it, said it was good to tow).

Back at ETI Reace fixes the coupling latch for us with a sledge hammer(hey, it worked) and we mention the squeals, groans and pops coming out of the E2E. So, he inspects the hitch, and raises our L bars a notch, adds 6 PSI to our tires and we're on our way.

Until it squeals while we're leaving the ETI parking lot. So we head back.

Reace re-inspects and adds grease to the knuckles(upper and lower) on the trunion bars as well as the hitch ball. We circle the ETI lot 4 - 5 times testing, still an occasional groan and pop, but a lot less frequent.

Now, 4000 miles on it, still an occasional pop or groan, but we're used to it.

We do have some(I wouldn't call it significant) wear on the L bars(but you're supposed to) and we've never had our L bars move or pins bend.

It sounds like yours may need an adjustment. Maybe over adjusted, would be my guess.

ETI gave us a hard copy of the E2E install/config guide, but a .pdf can also be found here :

Good luck

Hi,

Sorry, looking at your picture, are you missing 2 nuts/bolts, part #'s 5, 8 and 9 on page 2 of the E2 .pdf ? Or, is the picture of your L bars/trunions partially dis-assembled ?

Ours has 2 additional nuts/bolts on each L bar.

Since there seems to be some confusion about terminology...
  • the bolts with nuts on the inner side pull the link plates together
  • what the spring bars ride on are the "L-brackets", not the link plates
  • the retaining mechanism is the "L-pin"
Since the L-brackets are mounted onto studs welded to the link plates, the L-brackets and link plates shift together.

Those are the bolts which clamp the frame between the inner and outer link plates (items 6 and 7 in the diagram in the version of the manual which Bill linked). Without those, the brackets would be lying on the ground... they're just not visible in the photo in the original post, because they are covered by the L-bracket (item 4 in the same diagram, which is shown below).

The trunnions are at the hitch end of the spring bars; what we're looking at is the bracket at the trailer end of each spring bar.

Response to Comments

Thank you for the analysis and suggestions. The hitch was installed when I picked up my 21 at the factory. The solution suggested by the manufacturer for the "walking" (as the manual terms the movement of the supports) is supposedly fixed by insuring the brackets are bolted parallel to the trailer and then tighten evenly to the specified amount. (Check and check).

I noticed this problem on our first 3000 mile trip last March to California. I disassembled the L brackets and put the supports back into vertical. I tightened to over the recommended amount to insure they did not slip again. On this trip (I'm now outside of Montreal from the west coast) the problem showed up again within a week on the road.)

Tomorrow I'll take them apart again, realign, and break out the torc wrench. I'll also get a sledge hammer and straighten the retaining pins. "Flipping" them over as the manual suggests makes no sense to me whatsoever. They are both bent in the same direction and switching them will not provide "further positive" placement.

I'll get back to you with the solution I finally come up with. I was just curious if others have had this issue.

While you're at it, could you confirm that the bolts are in the correct holes in the link plates, and that the link plates have not bent?

I overlooked your comment in the original post about the bent retaining pins. Are you referring to the two L-shaped pins that hold the bars in place? They bent?? We just installed a 6,000# Equalizer hitch, and while we only have 1,000 miles on it, there are no signs of bending pins (or moving brackets, for that matter). I wonder about the heat treatment of the original parts, including the bolts holding the side plates on the rails. If the bolt quality is not up to specs, maybe it's not squeezing tightly enough on the rails. Same for the pins. Pure speculation on my part, but there just aren't many other things to consider.

Just one more thought on this....the nearby welding (they did our frame reinforcement) / trailer / snowplow / trailer hitch company that convinced me to spring for the Equalizer version of this hitch said that if it's too noisy, it's worth trying a little petroleum jelly on the friction surfaces of the L brackets. They said it's a poor lubricant and won't reduce the friction all that much, but it can help quiet things down. This may be heresy to some, including the hitch manufacturer, but I think I'd consider just a little dry lubricant of some kind. I just don't hear much at all about sway issues with double axle Escapes, and you obviously have a tremendous amount of friction between the bars and L brackets....possibly way more than you need. I'm not recommending it, but I think I'd try it if it were me.

Yes the bolts are in the correct location (top)...this leaves about 1/4 inch gap below the frame and the lower bolt. When tightened to 65# torc the lower bolt bends the lower portion of the link plates slightly together.

I've realigned and torced the plates. I'll check weight distribution before I head out for New Brunswick on the next portion of the journey. As mentioned I'll provide an update in a few weeks.
