Gerald_D Posted April 15, 2021 Share HiI am new here. Busy developing a local product to tighten up most loose towbars - those where the square tube is loose in the receiver. The problem is very much discussed in American forums, but I can't find that the locals experience it.Here are some examples:https://youtu.be/J_fHQmeOEGs?t=34 We (iTrekz) are testing a clamp with a similar function to those in the videos, but modified to cater for local towbars. The Toyota HiLux often has towbar by Bosal with a knurled screw which needs to be avoided. Further, they use a 54x54mm tube, bigger than the American/British 2inch tube. And the receiving square socket it welded up from laser cut plates that protrude down . . . . . therefore our anti-rattle clamp looks like the attached, different and stronger to those found on Amazon. Our development was for guys towing lightly loaded trailers (heavy loads don't rattle so much), then my son pointed out that bike racks are also an issue - and pointed me to this forum! Yours comments would be appreciated, thank you Link to comment Share on other sites More sharing options...
Steady Spin Posted April 15, 2021 Share My removable had some play. Recycled a Redbull can to remove the play. R22 later and my bike rack doesn't move anymore. DIPSLICK, Eddy Gordo, AdamA and 1 other 3 1 Link to comment Share on other sites More sharing options...
PhilipV Posted April 15, 2021 Share That is great!The removable towbar's rattle on my wife's previous car irritated me a lot. Bonus points if you can adapt it to be able to lock somehow, I reckon it is a question of time before we will see stolen trailers and bike racks with luggage and bikes etc taken with the towball and all.

Will play with two concepts and see if we can satisfy both. Link to comment Share on other sites More sharing options...

For longer term use I have replaced the "removal pin" with a bolt and lock nut. A com bination of a shim and TIGHTENING the bolt provided a nice snug fitting unit. Much more of a challenge to keep it removable .... get it to snug ... AND still be able to fit and remove easily .... Link to comment Share on other sites More sharing options...

So any device that makes it harder to steal will better. But I also understand why the other guy wants to be able to remove it quickly. Link to comment Share on other sites More sharing options...
Gerald_D Posted October 15, 2021 Share A bit of feedback on this thread . . . . My son, Sean, has now sold a number of these anti-rattle clamps mostly for HiLux owners who have seen this thread. It has not yet been "advertised" anywhere else. Has also been fitted to FJ Cruiser and Pajero. Sean now has a decent stock and will start a proper promotion campaign. Selling at R295 ex-Cape Town. info@itrekz.com Link to comment Share on other sites More sharing options...
dave303e Posted October 15, 2021 Share I drilled and tapped a 6mm hole in the top and side of the receiver. Grub screw in each solved all rattles. Edited October 15, 2021 by dave303e for got to add tapped... Steady Spin 1 Link to comment Share on other sites More sharing options...
Thug Posted October 15, 2021 Share Interestingly, my Navara has a similar issue. There is however on the removable section, a captive nut with a corresponding hole in the outer section, so when I next go to the hardware store I just need to get a big enough bolt, to fasten everything together.

Andymann Posted October 15, 2021 Share Bit of a thread hijack, but rattling towbars nonetheless, I always keep empty 1L milk sachet bags handy - a 12cm x 12cm square cut out of the sachet put over the ball before you hook the trailer takes away any play between the ball and the hitch - which stops that irritating noise of a trailer rattling when you brake or go over a bump.

Be careful of hardware store bolts - they generally are of the lowest strength grade and snap easily. Our clamp has 12mm threads equivalent to grade 8.8 strength and can be tightened to 90 Nm. This is really heavy duty and permanent. A different league to most of the other solutions above.

Gerhard765 Posted October 15, 2021 Share Seems that the rattling of the towbar is more an issue from others than for me. The bolt on the side of my removable towbar is adjusted to keep snug but loose. Still some movement but cant even say that i have ever heard noise of either towing a trailer or using a bike rack. Noise from trailer hitch on towbal would also probably be more. BigDL 1 Link to comment Share on other sites More sharing options...
