Post subject:  Sloppy Front End

Anyone with the X12 will know how much play there is in the front end. Theres 2-3 degree of play or more in both camber and toe. People have suggested to completely swap over to the AE or VBC front end as they minimizes the slop dramatically. I bought Xray because of its quality and brand (and the orange color from the 2015 edition). It feels kind of weird slapping on parts from other brands. Also, dispite all the slop, the car still drives fine...but I cant help but think how much better the car would feel if we took away the play.

Anyone have any tips on how to tighten the stock front end?

Hey,

sorry to hear about that, im sure we can sort that.

Can you see which part has the play?

Is it the fitment of ball into eyelet or the king pin inside the ball?

Sometimes i will lightly score the inside of the eyelet which the ball fits into, this slightly pinches the ball reducing wobble/play. Id do it four times, so once and 12, 3, 6 and 9 o clock if that makes sense? You do need to make sure everything is still smooth and free moving tho.

Let me know if this helps.

I agree and have the same problem on both my X10 and X12. The X10 being much worse. I haven't bothered to do anything about it as it doesn't seem to affect the car, but if anyone were to make a guide on how to reduce this on the XRay I'd be greatly appreciative.

Oops, forgot about this...Here are the play I observe.

Steering

Stock servo saver: 1-2mm play side to side
Steering link ball cups: Minimal Play

Camber

Pivot balls: 0.5-1mm play up and down, left and right within the upper and lower arms
Hinge pin: 0.5-1mm play with the upper arm

Heres a video

hello olly i have my x12 since 2 months and it has 50 hours of training on it and i think that the sloop concentrates in the upper eyelet i think the steel ball has eaten the plastic eyelet, if the surface is like the 5.8 balls is very simple to solve, a very good manufacturing polish will resolve that, i think the upper arm has some sloop in the 2 mm hig pin.. i think it is too small, while smaller the diameter it will has slopp more quicly.

i also see a lot of play in the front. Much more than e.g. in the AE's of my colleagues. It is the pivot balls in the upper and lower arm.
Olly, you mentioned that you score the inside of the eylet. I don't understand what exactly you mean, could you explain or maybe add a picture?

@ disaster 999, you mentioned exchanging some parts for AE parts. Which parts would you exchange? Aren't the AE parts imperial, whereas XRAY is metric, is this compatible?

The new steering blocks apparently have less play, but the steering blocks were not the problem imho.

Hey,

sorry for late reply


yes I find if the ball inside the eyelet is a little loose you can use a scapel blade to fix it.

Remove the ball from eyelet, then in four places (12,3,6,9 o clock) simply just put small line with sharpe scaple. This will leave a little groove which will hold the ball tighter. Always make sure the ball can still move freely. If it's tight after re fitting just move the ball around until free. Hope this makes sense :-)

Cheers

Is there any downside to the hard composite and graphite front suspension parts? Do they help keep out slop around the pivot balls? Are they significantly more fragile?

I was wondering, whether the play in the front suspension was reduced in the 2016 model. On the X12 website it is mentioned that the steering block was modified. However, it was my understanding that this was already done for the 2015 version. And the main problem are in my opinion the pivot balls in the upper and lower arm. Were these also changed, or does the 2016 version have as much play as the 2015? Does anybody know?

My 2016 version has more play than the 2015 version!

It is strange to hear that the play on the steering blocks is greater, it should not be. Please let us know where you from so we can have some team driver to look at your car.

Hi,

Can you take a photo of the part with the play? You should have some movement/play.

I have tested with both, zero play/wobble and with some play/wobble and on track its very difficult to notice the difference. Running with some play actually can make car easier to drive sometimes when driving over bumps etc.
