MC_D300tkb 300cc reverse trike bad wobble

[justincrediblem]

Was getting a wobble when the trike would sometimes slow down to around 20 mph. The wobble got more consistent. I found the rear tire was out of round. I ordered a new rear tire. While waiting for the new rear tire to arrive I was suggested by my dealer to align the front tires. They looked like they were out of alignment. I aligned according to his instructions and they looked more in alignment when I finished the task. The wobble got much worse and I couldn't even ride the trike. I assumed the alignment was making the out of round bad rear tire more noticable. I ended up getting the new rear tire mounted and balanced. I also got the front tires balanced and also got the right front tire remounted. (the right front tire was mounted in the wrong rotation from Sunny!) I put about 1,000 miles on the tire in the wrong rotation before noticing it. After a new rear tire, all tires balanced, a front alignment that looks correct, the bad wobble is still there. I noticed I have some play in a bushing too. Anybody else with these reverse trikes ever get a wobble this bad?

Here is a video of the wobble:

I'm just rocking the front tires back and forth in the video above.

Thats a lot of play , I what about the upper bushings on the oppisite end of the control arm . I would check the entire fromt end . Some parts need to be checked without weight on them . Thats a great video can you shoot another one at every moveable piont ?

The bottom left bushing appears to have the most movement. The trike is at a motorcycle, atv repair shop at the moment. The shop has experience with dirt bikes, off road side-by-sides, and racing motocross style atv's. I'm hoping with the experience of those type vehicles they can do something with the trike since it has a similar suspension/ front end.

Check those front tires and brake disks *very* carefully - I have a 150TKA, and the OEM tires were rubbish. The rear was out of round, one of the fronts was separating from the cord body on one side almost all the way around, and a disk was warped...
