It's happened to myself and most of the people I know who own Caster vehicles.

It's caused by the bushing ZX-0086 where execssive wear occurs on the bushing and the plastic around it.

The good news is that after about 10 packs it won't be getting any worse.

Also good news is you can deal with it by putting bearings there... I will ask my colleague to take photos of solution. I know only that he used some bearings from HPI Baja...

I myself will try to use one part that I hope will solve that problem also...

Thanks for the responses. In wiggling things around trying to find the source of the looseness, it doesn't appear to be the bushing ZX-0086, but rather the ball ends and fittings in the steering links and the the servo arm linkage. The play is not excessive in any one connection, but more the cumulative effect of the looseness at all of those connections.
I noticed it last night from the drivers stand during a qualifier while powering into a corner where the inside wheel actually moved side to side slightly. Almost like it was vibrating or fluttering. Can't say that it hampers the handling but it grabs your attention visually.
I'll see if I can do a YouTube to demonstrate what I'm talking about. Not real skilled with the video thing.

I have changed stock links from servo arm to steering with these (only made bigger holes in balls to fit M3 screws...):

Thumbs up

I've pretty much isolated the slop/additional play to the servo arm linkage so I'm going to work on tightening that up. There is play in the steering links as well, but one thing at a time.

Nice review,The only thing i did slightly different from you was the cut the shaft,not too bad,put some scotch 3m double sided tape strips underneath the battery trays and put a dab of ca glue on the screws going to the tray,and i turned the link the opposite way from you and having no issues.I also put one shim on side away from the gear on each diff to shim it.Thanks for doing this review as it will help alot of people out who may have some confusion building the kit.

yea I just had a really hard time taking a saw to a brand new perfectly good motor. This way works.

regarding the steering link, It only rubs on the right side. when the wheels are turned hard right, the metal portion of the turnbuckle hits the sway bar end link.

I just finished a build on my new caster EX1.5. The car went together very well despite a problem with the front and rear drive shafts, my kit had three rear and one front. I have to give a big thanks to Rick,Mike and Mikey with caster stepping up and getting the problem resolved very quickly. Mike with Caster racing USA sent new shafts and had in my hand in 2 days. I received a package from China also with a set of shafts and various other goodies. ALL I CAN SAY IS WOW , EXCELLENT CUSTOMER SUPPORT.

I had the same thing on my first kit from 2010, but clearance was not an issue with my latest one built last night. Metal parts tolerances and quality are up drastically since I last built a Caster kit. Quality and fit of plastic parts (diff housings especially) still needs to be improved. Overall though, the build process has gone much smoother than last time.
