HELP

[breezer]

Was out with my X10 yesterday, had a slight problem when I accelerate the car pulls to the LEFT not to much but very noticable. this is not the steering trim,I built all the shocks push rods using my digital vernier,I did notice the left rocker shaft was ever so slightly differant to the right one. Unfortunatly I broke a front lower wishbone before further testing. Question one do you "GUYS" with knowledge of this think it is my rear diff to tight or a other problem, number to does the "PRED" eat front wish bones like the XX4.Thanks in advance, MARTIN.

I had a similar problem with mine a while back, and after checking and double checking all of the obvious moving parts, such as the rockers etc., it turned out that a lower hinge pin on the front was slightly bent, and when the front lifted under acceleration, one side lifted more than the other due to the wishbone binding on the hinge pin, pulling the car to one side. It was much more noticeable under braking on my car though - you have a broken wishbone to replace, this is the ideal time to check them!

The X10 is a strong car, and does not go through wishbones at the rate of xx-4's seem to do, but if you crash enough it will break.

As for your rear diff being too tight, you need to check it by holding it in either one of those "diff tools" or between two screwdrivers in the output shafts, and try to rotate the diff wheel with your thumb. You should ONLY just be able to move the diff wheel ever so slightly.
You can check this in your car by holding the front wheels still and then turning the rear wheels, you should feel the diff slip but again, only slightly.

Hi Breezer
Between the measuring of the pushrods & shocks length and the ground there are a few areas you should check, like Chris suggests the hinge pin is one. Following his lead about the one wheel dropping lower than the other, I would suggest you take hobby knife in hand & using it's point lift the front of the car from the table slowly.
If you place the car's front wheels as close as you can to the edge of the table (but not so far as it will roll off when you put it down) all you need to do is find center of balance with the point of the blade.
Now take note as you're lifting if one of the wheels/tires leaves the table before the other, If this is the case, you have found the problem. just back track part by part until you find it.
A few months ago I managed to break the front gearbox top on mine, at the track, no problem I thought as I had spares.After switching the broken top for the new one I did the very same test I described above only to find a huge difference between the wheels.
looking from above the car I could see the rockers were not equal/symmetrical, after further investigation I( found the holes for the rocker shaft or pivot holes were not drilled at the same angle (I.E. one pivot was more upright than the other, side view).
I thought it was a one off mistake ( the holes & tapping are done by hand), so when I got home I took the other front g.b. top out of it's bag & compared the angles using two shafts I had (I think they were punches) and guess what......they were wrong as well, I still have them lying around. They can't be used.
Have a measure like I (and Chris) suggested, you'll feel better if nothing else.

It is possible to get the set-up wrong ona Pred due to what is adjustable and how it is adjusted.

I for one have always struggled with rear toe-in, so I got one of these:

I took a risk as it is for a touring car, and it did not fit (width wise) when it came. I emailed the guy and he has made me a toe-in plate wide enough for the X10. He said he will shortly be delling them on EBay.

My car went very well last week, and I was 100% confident that all the wheels were pointing in the right directions! ;D

Cheers,

G

Thanks all, I will try out all the suggestions,I am tottally stripping the car.I have soknowledge of where I may have gone wrong but all imput helps.I notice the rocker posts on mine where not equal. Will play about untill it is right as the car is awsome. May have to wait untill it gets raced in ernest due to other commitments.Good luck to all and cant wait to here what IANs next project is. Good Racing,MARTIN

G,

I have always (i think with success) just used a camber guage.
Turn the car up onto where the wing is and measure them that way. You should at least get them fairly close.
Then i measure the inside edge on the tyre to the chassis to verify this.
