Rear drive shaft problem!

[Chris Griffiths]

Ok I noticed this problem last week indoors but it was much more of a problem today outdoor on a bumpy surface. I have the longer rear axels, and ive used 2 bearings, the tube spacer and the little spacer on inside of driveshaft. but my drveshafts are half in half out of the outdrives so if i hit somthing they pop out. after consulting the lads at the club I was told i need to add another bearing. so i did this, i had to remove the small spacer or you couldnt see hole for pin atall, but even with this removed I couldnt get pin in to hold on outside??? so i had to shim it up as best i could.

Does anyone else have this problem? Any better solution?

you should have bearing, bearing, tube, bearing, shims as required then wheel washer and the pin. if what you mean is the driveshafts are coming out when the wheels are at full droop then you have too much droop, caused by, wrong length shock shafts, unscrewed ball ends, no limiters ans other such things.

[Darren Boyle]

If the axles are fitted correct with the spacers as they should be, the driveshaft pin should be snugly inside the diff outdrive.

What shocks are you running and what length are they? Sounds very possible that you have too much rear droop, maybe you can measure this on your car and one of our team guys can confirm this for you....

[Chris Griffiths]

its set up eaxactly same as the ellis stafford set up with losi shocks. 3mm limiter inside.

What length Lois shock bodies and shafts are you using (it should be the 0.9 bodies with 1.0 shafts and NOT the 1.2 bodies or shafts), worth double checking this and pherhaps measure your car at full droop fom the bottom of the chassis to the ground too....

[Chris Griffiths]

Shock length is 91mm when going from middle of screw to middle of screw!

How do i kno if my shock bodie is 1.2 or watever??

With that length of shock your bodies and shafts sound about right. My own shocks are coming in at between 89/90mm in length. With that in mind I would check that your shock bottom balljoints are on "all the way", make sure that the top shock mounting screws are not bent and if all else fails add another 1 or 2mm of limiting insdie your shocks to cure your problem......

were my ball joints are, you can see quite a bit of thread but I had to do this to get it the same length as ellis was running??

Also another thing is I had tons of play in my rear wheels, in and out play.

I seen people put another bearing on the inside but this didnt work for me atall

I "believe" that when Ellis measures shocks he measures the overall length, (but I will let him confirm that). If you think about it, he would not be adding limiters inside the shock to make it shorter and then unwinding the shock bottom to make it longer again, the two counteract each other.....

(I would suggest to get those shock bottoms wound in all the way!!)

You may need to snap some quick photos of this so we can all see how you have assembled it in case anything is astray..........

Will do!!!

heres exactly how i set up driveshaft it was obviously inside the hubs!

Heres how ive got my ball joints

The first spacer on the axle is not big enough. i use an old bearing middle to space

Yes as I said this made it impossible for me to put the pin in!!

[MikePimlott]

Are you using plastic or metal hubs and are the bearings sitting in the hub fully ? Using a bearing on the inside shouldnt stop the pin going through the axle .

Plastic ones! im baffled by it, everyone was at the track today!

Those axles look like the new revised "mid" length version. Is it possible the Ellis set-up you have is from when he was running the "long" version? If so then it's highly likely the driveshafts would pop out.

[Chris Griffiths]

The set up sheet and drive shafts came in the Ellis x6 kit.

First, reduce the shock length as mentioned above (which is what I think is your problem for the reason given in post # 10 above - I have also highlighted the reason now too).

Second, are they definatley X-Factory 5661 long axles and not standard AE B4 ones or anything siily. The new X-Factory axle should measure 9.2ish mm from the very inside of the axle to the start of the pin hole (ie how much axle you have to "slide" things on to). The overall length of the axle from one end to another should be 35.9mm

It is worth noting that the newer 5661 axles (supplied with our new C-CVD's), are very slighlty shorter than the previuos 5660 axles (same as Losi BK2) to prevent the plunge issues experienced on some set ups prior. The Ellis conversion kit only included axles (not complete driveshafts - since they were not out at the time of release) The spacer supplied with the newer type axles is slightly thinner to compensate for the marginally shorter length
