Big Rock Big rock wobbly front wheel

[stevebick]

Hi all

received my big rock 4 weeks ago, I noticed a wobble on front left wheel out of the box, have since done lots of grass bashing abc not noticed any issue, but tried a road speed run yesterday abc wobble does prevent straight line run, any ideas how to fix or what could be ?

thanks

When I got mine it actually had a missing bearing on the outer side. Check all the bits are there the same as the opposite side. Mine was the same wheel as well.

Wobbles are pretty standard, but, check that your drive shafts are tight at the hubs, you'll need to split the shaft and fit a 2mm hex driver down the shaft and tighten it, check the diff side while you're at it.

Thanks both, will check bearing and drive shaft, it adds to the fun until keeps hitting the curb !!

Try swapping 2 tires around and see if the wobble changes at all. It could be in the tire or the wheel itself.

Make sure your caster blocks have a screw in the top and bottom. The bottom one tends to come out easily.

So after checking it all out and swiping wheels around it’s the wheel which is the problem, at least proves bearings and drive shaft are ok

Can you please explain what part of the wheel is the issue? Is the hex in the wheel damaged ?

 

[stevebick]

Hex seems ok on drive shaft and from looking in wheel, when I move the wheel to different locations it always the same wheel that wobbles. Must be a twist in the plastic ?

When I got my big rock back in November all 4 wheels wobbled out of the box. I contacted horizon and sent them a short video and they sent me a new set.
I believe that they were over tightened during assembly causing the hex portion of the wheel to warp, each wheel had cracks in that area as well.

Thanks, I will drop them a note plus video etc, I’m in the uk so not sure if they will post out but worth a try.

I had a rear wheel wobbling issue. It was the outer wheel bearing that had broke. I replaced the bearing but still some wobbling.
It was the broken bearing that had eaten some of the hub plastic so the hole diameter was about 1mm wider.
I also replaced the rear hub and now all was good.
Some wobbling is ok, it's a car for bashing not carpet racer

I had one wheel wobble and it is the material in the section where the hex sits is very thin, I moved my wheel round to I found the spot that was the most off center and then grabbed the wheel while it was on the axle and bent it back to the center, it is now nearly spot on. I think this may be risky bending the wheel back and forth, but it is good to have them running true.
