Hey Guys, i'm now experiencing my front tyres of my Tamiya tb-01 chassis binding/locking up sometimes. I have no idea why this might be happening, any help would be appreciated. :)

Check your bearings, also check that your wheel nuts aren't to tight. Make sure your rims clear your hubs and don't rub.

We've had a look into the front driveshaft and all that and greased it all and it still happens. This is stock steering so maybe can't handle the power of the new 12t motor i've put in. Is there a way that by upgrading the steering that maybe it could then handle this power.
 
Steering shouldn't have anything to do with the wheels "locking up". It's going to be something in the drive train. Look at the differential make sure the ring gear and pinion are good and not missing teeth or too tight. Check the internal gears and pins of the diff to make sure nothings broken. Make sure your outdrive cups are not rubbing on the a arms etc. It has to be something in the drivetrain if the wheels are all clear of the hubs and bearings are good and hex's aren't cranked down to tight not allowing the wheels to turn.

Already checked all this and there are no problems that i can see, however someone else has said that it might have something to do with the 12t motor draining all the power from the steering servo, is there a way to fix this?
 
Ok so when you say your front wheels "lock up" I think they stop spinning and lock up like having a break applied in a real car. So is it when they "lock up" they stay pinned in one spot and won't move side to side and allow you to directionally turn?

Sorry i shouldn't of said lock up because they don't, to describe it basically it almost looks as if the steering goes to far each way then makes grinding noises.
 
You could have stripped out the servo gear set. check you EPA settings. and reduce the amount of steering side to side.
 
Ok so that sounds like your servo is going. Are you able to adjust your steering on your transmitter? I read your other post as well about the issues and have you gotten a new reciever and transmitter yet as this could fix the issue. But if your hearing grinding from the servo odds are the gears are stripping inside and needs replaced this would also give the jerky feeling as the servo teeth are not smoothly turning.
 
I've just tried out a spare new servo and the same problem is happening, its ever the amount of power from the motor or the front gearbox is being funny?
 
Again The motor doesn't power the servo. It's the motor drawing the power from the servo. To check to see if the problem is the motor drawing all the power use a external receiver battery. This comes back to the BEC on the esc.

Ok i'll order an external receiver battery tonight, but what battery would you guys recommend?

I've ordered a 4 cell battery holder anyway, but I've had a look at the bearings at the front and on the left side the outside of the bearing is moving as well which shouldn't be happening. I have a feeling this might of been the cause from the beginning as the last motor isn't as fast, the new one is highlighting this problem as its faster.

then put shims in to hold the bearing in
 
Does it do it when you turn the other way? I think the you will have take the whole front off and see what is binding. It appears to be a dog bone and another bearing inside the steering hub.
