Magico 69 Posted February 12, 2021 Share Posted February 12, 2021 Hi! I am total novice to R/C, recently bought SMT10 RTR brand new and only had it out twice. After its second run and couple of minor jumps on grass I discovered a serious problem with front axle. Both front wheels wobble a lot. Nuts are tightened correctly. EPA is set correctly. Hexes sit tight. There seems be a little bit of expected play in the hubs but hexes seem to be spinning fine. It kind of feels like when hex is too thin for the wheel and doesn’t hold it snug. Also wheels rub against the steering links inside the wheel when turning now, causing them to scrape and lock. I feel like both problems might be related. It doesn’t seem like anything’s been bent or damaged. Please see below vids that explain my issue. I’d appreciate any help from fellow Axial owners, as I am quite desperate to get it running for the summer 😊 IMG_3865.MP4 IMG_3864.MP4 IMG_3866.MP4 Quote Link to comment Share on other sites More sharing options...
Stormbringer Posted February 12, 2021 Share Posted February 12, 2021 im thinking you may have bent the axle ? if you spin that wheel does it wobble/orbit at all ? Quote Link to comment Share on other sites More sharing options...
Magico 69 Posted February 12, 2021 Author Share Posted February 12, 2021 @Stormbringer Hi! Thanks for your help! Both front wheels spin freely but wobble like it they were out of balance. I assume it doesn’t go straight now but I could only test it on carpet. Both wheels touch the steering link bit at full lock so when throttle is applied wheel that rubs fully locks as in the video above. Quote Link to comment Share on other sites More sharing options...

sunny Posted February 12, 2021 Share Posted February 12, 2021 Remove both front wheels check the axle is not bent, if not bent it may simply be a case of using wider wheel hexes plenty available on ebay from 3mm to 12mm. You may want to change the bar from servo and steering rod to metal as well as they are quite bendy. As for hitting the link mine is same I just turned down the EPA on my transmitter so it wont rub but not turning circle is not great.

Stormbringer Posted February 12, 2021 Share Posted February 12, 2021 (edited) certainly something not right there maybe axle bent or bearings are knacked at wheel end of axle but not sure mate theres something bent or loose there Edited February 12, 2021 by Stormbringer Quote Link to comment Share on other sites More sharing options...
sunny Posted February 12, 2021 Share Posted February 12, 2021 You need to check the front diff and axles something is not right or a bad bearing maybe? Quote Link to comment Share on other sites More sharing options...
sunny Posted February 12, 2021 Share Posted February 12, 2021 Take wheels and axle off and check not other way really Quote Link to comment Share on other sites More sharing options...
Magico 69 Posted February 12, 2021 Author Share Posted February 12, 2021 @sunny @Stormbringer thanks a lot for your help! I’ll disassemble axles on my days off and check if anything is bent or if bearings are damaged. When you say bent axle you mean the whole big plastic assembly that runs across the wheels or just the hub axles that hold the hexes? Somethings wrong there I just need to find out what! Thicker hexes also seem like a plan! I’ll keep you both updated of any progress in this thread 😊 1 Quote Link to comment Share on other sites More sharing options...
Stormbringer Posted February 12, 2021 Share Posted February 12, 2021 if bent it will be metal parts inside the plastic part or a bearing has come apart or badly worn 1 Quote Link to comment Share on other sites More sharing options...

What hex thickness would be perfect for stock SMT10 to bring the front wheels out a bit and don’t cause too much strain on the axles?

sunny Posted February 12, 2021 Share Posted February 12, 2021 About 10mm should be ok just make sure there is enough thread on the axle to do up the wheelnut 1 Quote Link to comment Share on other sites More sharing options...
