X11 08 - Problems!

[samd]

Just purchased a x11 08 - Just got a few problems - First the front upper wishbone still has forward/backward movement with all the kit washers on ,7, looks like in needs 2 or 3 more. The head of the countersunk ball joint screw on the steering catches on the edge of the chassis as the steering turns, and finally the rear propshaft bearing, when the rear gearbox top is fully clamped down, still as apox 1/4mm movement up and down:mad: - I had this same problem on my xrs, which came second hand so i put it down to wear. I have checked without propshaft in, bearing is moving up and down. Everything is clean from burrs and clamped down fully. Anyone else had this problem??
Any other tips...

Hi,
front upp wishbones:
when you tighten the 2 screw of the x-brace, you push the x-brace on front of the car and lock that?
rear propshaft:
i use a second ball bearing on rear pinion for more precision when i close the gear top box.

Thanks will try loosening xbrace and push forward. Can you give me more info on how to/what to use for second bearing. Thanks SAM:)

[restimax]

it's a 6x12x4 (or 3,5) ball bearing not flanged!
you put this on pinion steel, this ball bearing replace the collar in alu.

Cheers!

some gearbox tops have a small burr around where the 4 screw holes are for mounting the carbon brace + nose cones. make sure these are removed so that everything can sit flush. if your xbrace isnt centralised it will cause the extra movment and also the steering to catch. on mine i have used countersunk screws to hold the xbrace down but this does, sometimes require a little fettle with a dremel/hobby knife to make everything smooth. there is a little play in the rear of the propshaft but not a large amount and nothing to worry about normally.I have seen some people drill a hole in the gearbox top and m3 tap it, then use a small grub screw to allow you to wind the play out of the bearing area, as i say i havent had to do this and havent had the problem but did see it used on older preds

By any chance have you got the newest front upper arms?? If you have you'll need more than the 7 washers.

Rear prop movement, I've done the same as above put a second bearing in.

There's two solutions to the steering problem, either recountersink the holes or the easier option is to slightly dremel the chassis where it catches.

Thanks - the upper arms are from pred x11 08 so will be latest - I will add more washers. Also will do gearbox mod - shame i have to on a new car tho.
Thanks for the advice everyone

The play on the prop doesn't really harm anything, I ran mine for about 6 months with the play in it.

Mine has a little vertical movement at the rear of the propshaft but it hasvn't had any negative effect to date.

[restimax]

that movement is orrible!;)

I was assured by Lewis that there is a reason for it to have that moovment.. :)

[samd]

I can see why the front to back movement is needed - to account for chassis flex - but why should a bearing move 1/4mm up and down in in the moulding?

[niggs98]

doesnt sound right to me. you have used the right screws in the front section of the gearbox top and pulled them all the way down havent you. if the g/box top isnt flush then you will get a lot of movement. i get 1.5 ish mm of movment which is worn

[samd]

1.5mm!!!! up and down?

which?:D

take the gearbox tops off, and check that the mouldings are clear of swarfe, especially around the area that the outdrive bearings sit, and across the front face.

This used to be an issue with the X10's and it is possible that the X11 may suffer from the same problem every once in a while.

If the gearbox tops are "clean" and there is no other obstruction on the gearbox top or chassis, ensure the correct screws have been used to mount the gearbox top, and are properly tightened down.

If that still doesn't sort the problem out, get another gearbox top.

There should be no up/down movement in the propshaft on the pred's because if there is, you will strip very many pinions and diff gears.

[niggs98]

1.5mm!!!! up and down?


yes up and down. mine is worn tho and should be relaced as it has had a lot of use

[RLGfx]

i cured mine with some insulation tape...

I'm so cool... :D:cool::D

[Kopite]

it worked too, but you're not cool

[niggs98]

but you're not cool


as much as i hate to agree with stan ............ he is right :wtf:

[RLGfx]

no i am.... you just don't know it... :thumbsup:

i still drive like a bitch though.....

[samd]

Not good - the up and down movement isnt due to swarfe or incorrect screws its the gearbox moulding.
I have added a second bearing instead of the alu pinion spacer and drill and tapped 3mm hole above the flanged bearing and put a short screw through the gearbox top to nip up the slack in it (niggs98 s idea) - second added bearing seems to fit without need to be nipped up. You need to be precise with the hole so the screw will pinch the bearing between the flanged bit and the pinion. Mine now has no play and very smooth. This makes meshing motor pinion and spur easier and must reduce wear on pinion/ crown gear and gearbox/chassis bearing mouldings.
Just wacking some insulation tape in could have been easier tho.........!

Ordered my pred 08 2 weeks ago - still waiting for a cancelled order refund and missing balls from big bore shock kit - please contact me teamXtreme I have sent you a few emails with no response SAM D

The slack has been a std feature for many years i'm affraid - most people do fix it with a grub screw as you have.

The second bearing is also a good idea as you say, supports the spur better too. I also put a second bearing in the front ;)

lol,I was just about to say that!
I did it in all my pre X10 cars, wasn't needed in the later ones, BUT some moulding are worse than others so in your case that small screw will just be fine.
Nothing else to worry about.
