I have a 1995 Cobra trailer for my Discus. The tongue
strut is shot and needs to be replaced. Can anyone give me some advice on how to do this? I removed the hitch, all the bolts along with the bolts holding the strut in but can not pull the strut out of the front. Thanks for the help and advice, Brian |

Use your vehicle to pull it apart. Install the hitch again Tie your trailer to something sturdy hook up your vehicle, pull it off by driving forward. If you have a shop try to set-up a lever arrangement. If the tongue strut did not move in normal operation you may need several 100 lbs of force to get it moving.

Actually, the tongue strut still moves just fine. The
strut has lost it's charge so it will not push the trailer away from the tow vehicle at a stop. I just can't figure out how to remove the strut from inside of the tube that goes into the trailer.

No two Cobra trailers seem to be alike so I'm not sure if mine (ca.
1992) is a close match to yours. But my trailer's strut isn't a gas spring, it's a damper; i.e., it doesn't push the trailer away from the tow vehicle at all but rather damps the movement during acceleration and braking. With older trailers which lacked such a damper, hard braking would sometimes cause the surge-brake sliding tongue to compress suddenly, applying full brakes and often causing the wheels to hop off the ground at the slightest bump in the road. When they landed again with the brakes locked, the tongue would extend just as quickly before being compressed violently, repeating the cycle and leaving little chirp marks of rubber on the road. To remove the damping strut, I have to remove the inner tube to which is bolted the hitch. That's usually (see below) pretty easy: you can leave the hitch on the inner tube; just remove the big bolt (maybe two, I'm not sure) that holds it all together and slide the inner tube forward out of the outer tube. You must remove remove the bolt that retains at least one end of the damping strut first, of course. Years ago, after the trailer sat for a while, moisture apparently caused the two large plastic bushings in which the tube slides to swell, plus the inner tube rusted/corroded. The tongue assembly was frozen in place no matter how hard we pulled (we didn't try Udo's trick). I chained a long lever arm to the inner tube and was able to rotate the tube slightly back and forth while I slowly pulled it out. I had to clean up/smooth the inner tube's surface where it slides in the bushings. More important, I also had to open up the bushings a little bit with a sanding wheel on a long shaft (the front bushing is accessible but the aft one is recessed in the outer tube) before it would all go back together properly. Keeping the bushings lubricated properly minimizes this problem. After I use a grease gun on the fittings, I remove the bolts holding the two tubes together and rotate the inner tube 360 degrees to distribute the grease all the way around.

Here is the response I received from Agnes (see below)
at Cobra. I have a couple of ideas that I want to try but was interested if anyone else has any suggestions. Thanks Brian (snip) Hello Brian, sorry to let you wait. I had to investigate first because I am not too familier with this job and Alfred is not around. I was told that this task is very difficult for one unexperienced. You just need to make sure that you have removed all the bolts and then fumble around until it gets out. It is kind of tricky and I heared the boys cursing when they did it. Only if you don't get it done you would at least also remove part Nr. 8 but normally it should not be necessary. Wish you good luck. Regards Agnes |
