Bike Rack receiver wiggle

On my Fifth, we had the factory install a hitch, specifically for a bike rack (I already knew from the forums, bumpers were suspect!). After going through all the brands, found that Swagman was about the only game for trailer rated racks.

Leaving in about 3 days, and was finally able to get my new rack (Swagman XC) and the Fifth in the same place. The Swagman is the one that comes with an adaptor for bumper mounting, if desired. No, I didn't use it.

Turns out the receiver is under and behind the bumper. In this configuration, bikes are hitting the rear window of the fifth. So off I went to get a 6" receiver extension.

That gives me good clearance. But, if I lift the whole assembly fast and hard, to simulate going over a bump, there is a pretty large amount of up/down play. I cannot get the handlebars to be less than about 2" from the window, so I'm hoping there won't be any really big bumps in my future. The play seems to be due to the looseness of the rack tube going into the extension, and then additional from the extension into the receiver.

Any suggestions on how to stiffen everything up so there isn't much play? Or am I worrying unnecessarily?

  • I also drilled and tapped to horizontally stabilize a receiver with my spare tire. Sounds like one bolt on the top of the receiver will work for you.
  • Ditch the extension and buy a peice of 2" square tubing lone enough for the clearance needed to replace the original that is to short. Drill the holes needed and weld a 5/8" nut on the inside to bult it to the reciever.
  • I would leave the play in and tie down the bikes with bunge cords to minimize the bounce. If you take the play out the stress will increase on the receiver. The bounce acts like a bumper.
  • I had this same bike rack wiggle issue years ago when running a Swagman rack in the receiver mounted on our Explorer but solved it completely by using nylon straps secured at one end to the bikes & at the other to the roof rack on the vehicle and pulling them tight. The same technique would work with any trailer but the problem would be the lack of anchor points on the trailer that the straps could be attached to. The best solution would be to run lag bolts with a loop on the end through the rear wall of the trailer but I personally sure wouldn't want to be drilling holes into any rig I owned just for the purpose of carrying bikes. :E

    The Swagman has a threaded tube hole, and uses a threaded hitch pin to tighten things down. It reduces the play somewhat, but since the inner tube O.D. is less than the receiver I.D., there is still some.
    U-Haul has a retrofit version with lock (http://www.uhaul.com/MovingSupplies/Hitch-towing-security/Anti-Rattle-Receiver-Pin?id=16372). It has a U-shaped insert with nut that goes inside the interior of the inner tube, then you thread and tighten the bolt down before locking. Not sure it will reduce the play much, but might be worth the experiment.

    The Hitch-Vise seems to be the answer. But won't be able to get it before we leave. I'll ponder whether there is something at the Depot I can use to kludge together that would get me by for this trip.
  • I drilled and tapped two holes in mine. Held rock steady for the 2 years I had it.

    Until I found the one at Hitch Rider. This will keep everything tight.

    Their Hitch Vice is the best and easiest one I have come across and it really works.


    Interesting. I may try this, thanks.
